A random number table was used to divide the participants into study and control groups(n = 70 per group). The study group underwent TUCBDP. The prostate resection surgical time, intraoperative blood loss, bladder irrigation time, catheter indwelling time, length of hospital stay, International Prostate Symptom Score(IPSS), maximum urine flow rate(Qmax), residual urine volume(RUV), changes in the International Erectile Function Score(ⅡEF-5) score, serum prostate-specific antigen(PSA), quality of life(QOL) score, and surgical complications were compared in both groups.RESULTS The operation time, intraoperative blood loss volume, bladder flushing time, urinary catheter indwelling time, and length of hospital stay were significantly lower in the study group than in the control group(P < 0.05). There were no significant differences in the IPSS, Qmax, and RUV measurements between the study and control groups(P > 0.05). However, at 3 mo post-surgery, the IPSS and RUV measurements were both lower(P < 0.05) and Qmax values were higher(P < 0.05) compared to the pre-surgery results in both groups. The ⅡEF-5 scores before and 3 mo after surgery were not significantly different between the study and control groups(P > 0.05). At 1 mo after surgery, the ⅡEF-5 score was higher in the study group than in the control group(P < 0.05). The serum PSA levels and QOL scores before treatment and at 1 and 3 mo after treatment were not significantly different between the study and control groups(P > 0.05). However, lower serum PSA levels and QOL scores were observed after 1 and 3 mo of treatment compared to pre-treatment levels in the study group(P < 0.05). The surgical complication rate of the study group(4.29%) was lower than that of the control group(12.86%;P < 0.05).CONCLUSION TUCBDP for BPH and transurethral resection of the prostate can achieve better results, but the former method is associated with less surgical trauma.展开更多

This retrospective study was conducted in patients who underwent M-TURP at Peking University First Hospital between 2003 and 2013. A total of 1680 patients who had undergone M-TURP were identified, including 539 patients in the noncystostomy group and 1141 patients in the cystostomy group. After propensity score matching, the number of patients in each group was 456. Smaller reductions in hemoglobin and hematocrit （10.9 g vs 17.6 g and 3.6% vs 4.7%, respectively） were found in the noncystostomy group. In addition, patients undergoing surgery without cystostomy had their catheters removed earlier （4.6 days vs 5.2 days）, required shorter postoperative stays in the hospital （5.1 days vs 6.0 days）, and were at lower risk of operative complications （5.7% vs 9.2%）, especially bleeding requiring blood transfusion （2.9% vs 6.1%）. Similar findings were observed in cohorts of prostates of 30-80 ml and prostates 〉80 ml. Furthermore, among patients with a resection weight 〉42.5 g or surgical time 〉90 min, or even propensity-matched patients based on surgical time, those with cystostomy seemed to be at a higher risk of operative complications. These results suggest that M-TURP without suprapubic cystostomy is a safe and effective method, even among patients with larger prostates, heavier estimated resection weights, and longer surgical times.展开更多

In this retrospective study, we assessed whether transurethral seminal vesiculoscopy is feasible and effective in the diagnosis and treatment of hemospermia. To address this complex condition, we report our experience in a population of patients treated with transurethral seminal vesiculoscopy. From February 2006 to July 2008, 72 hemospermic patients underwent transurethral seminal vesiculoscopy examination and treatment at our urology center. Transurethral seminal vesiculoscopy was performed by a 7-F or 8-F rigid ureteroscope. The endoscopic procedure was conducted through the normal anatomic route of the seminal tracts. In this series, the mean follow-up period was 21.7 months. Definite diagnosis was made for 93.1% patients, and 94.4% patients were cured or showed a decrease in their symptoms. Postoperative complications were not observed in the study. Our study proves that transurethral seminal vesiculoscopy is effective in the diagnosis and treatment of hemospermia with minimal complication.展开更多

Transurethra...Benign prostatic hyperplasia (BPH) is highly prevalent among older men, impacting on their quality of life, sexual function, and genitourinary health, and has become an important global burden of disease. Transurethral plasmakinetic resection of prostate (TUPKP) is one of the foremost surgical procedures for the treatment of BPH. It has become well established in clinical practice with good efficacy and safety. In 2018, we issued the guideline “2018 Standard Edition”. However much new direct evidence has now emerged and this may change some of previous recommendations. The time is ripe to develop new evidence-based guidelines, so we formed a working group of clinical experts and methodologists. The steering group members posed 31 questions relevant to the management of TUPKP for BPH covering the following areas: questions relevant to the perioperative period (preoperative, intraoperative, and postoperative) of TUPKP in the treatment of BPH, postoperative complications and the level of surgeons’ surgical skill. We searched the literature for direct evidence on the management of TUPKP for BPH, and assessed its certainty generated recommendations using the grade criteria by the European Association of Urology. Recommendations were either strong or weak, or in the form of an ungraded consensus-based statement. Finally, we issued 36 statements. Among them, 23 carried strong recommendations, and 13 carried weak recommendations for the stated procedure. They covered questions relevant to the aforementioned three areas. The preoperative period for TUPKP in the treatment of BPH included indications and contraindications for TUPKP, precautions for preoperative preparation in patients with renal impairment and urinary tract infection due to urinary retention, and preoperative prophylactic use of antibiotics. Questions relevant to the intraoperative period incorporated surgical operation techniques and prevention and management of bladder explosion. The application to different populations incorporating the efficacy and safety of TUPKP in the treatment of normal volume (< 80 ml) and large-volume (≥ 80 ml) BPH compared with transurethral urethral resection prostate, transurethral plasmakinetic enucleation of prostate and open prostatectomy;the efficacy and safety of TUPKP in high-risk populations and among people taking anticoagulant (antithrombotic) drugs. Questions relevant to the postoperative period incorporated the time and speed of flushing, the time indwelling catheters are needed, principles of postoperative therapeutic use of antibiotics, follow-up time and follow-up content. Questions related to complications incorporated types of complications and their incidence, postoperative leukocyturia, the treatment measures for the perforation and extravasation of the capsule, transurethral resection syndrome, postoperative bleeding, urinary catheter blockage, bladder spasm, overactive bladder, urinary incontinence, urethral stricture, rectal injury during surgery, postoperative erectile dysfunction and retrograde ejaculation. Final questions were related to surgeons’ skills when performing TUPKP for the treatment of BPH. We hope these recommendations can help support healthcare workers caring for patients having TUPKP for the treatment of BPH.展开更多

TSV was performed in 419 patients with an initial diagnosis of persistent hemospermia at Shanghai Changhai Hospital （Shanghai, China） from May 2007 to November 2015. TSV was successfully performed in 381 cases （90.9%）. Hemospermia was alleviated or disappeared in 324 （85.0%） patients by 3 months after surgery. Common intraoperative manifestations were bleeding, obstruction or stenosis, mucosal lesions, and calculus. Endoscopic presentation of the ejaculatory duct orifice and the verumontanum was categorized into four types, including 8 （1.9%）, 32 （7.6%）, 341 （81.4%）, and 38 （9.1%） cases in Types A, B, C, and D, respectively. TSV is an effective and safe procedure in the management of seminal tract disorders. This study may help other surgeons to become familiar with and improve this procedure. However, further multicentric clinical trials are warranted to validate these findings.展开更多

We searched PubMed, Embase, Web of Science and the Cochrane Library. The pooled estimates of maximum flow rate, International Prostate Symptom Score, operation time, catheterization time, irrigated volume, hospital stay, transurethral resection syndrome, transfusion, clot retention, urinary retention and urinary stricture were assessed. There was no notable difference in International Prostate Symptom Score between TURP and PKRP groups during the 1-month, 3 months, 6 months and 12 months follow-up period, while the pooled Qmax at 1-month favored PKRP group. PKRP group was related to a lower risk rate of transurethral resection syndrome, transfusion and clot retention, and the catheterization time and operation time were also shorter than that of TURP. The irrigated volume, length of hospital stay, urinary retention and urinary stricture rate were similar between groups. In conclusion, our study suggests that the PKRP is a reliable minimal invasive technique and may anticipatoriiy prove to be an alternative electrosurgical procedure for the treatment of BPH.展开更多

Methods： Between March 1999 and March 2004, 629 patients underwent TURP in our department for the treatment of symptomatic BPH. All patients underwent transrectal ultrasound examination. In addition, the flow rate, urine residue, International Prostate Symptom Score （IPSS） and quality of life （QOL） were recorded for those who presented without a catheter. Finally, the erectile function of the patient was evaluated according to the International Index of Erectile Function Instrument （IIEF-5） questionnaire. It was determined that ED existed where there was a total score of less than 21. The flow rate, IPSS and QOL assessment were performed at 3 and 6 months post-treatment. The IIEF-5 assessment was repeated at a 6-month follow-up. A logistic regression analysis was used to identify potential risk factors for ED. Results： At baseline, 522 （83 %） patients answered the IIEF-5 questionnaire. The mean patient age was （63.7 ± 9.7） years. The ED rate was 65%. After 6 months, 459 （88%） out of the 522 patients returned the IIEF questionnaire. The rest of the group was excluded from the statistical analysis. Six months after TURP, the rate of patients reporting ED increased to 77 %. Statistical analysis revealed that the only important factors associated with newly reported ED after TURP were diabetes mellitus （P = 0.003, r = 3.67） and observed intraoperative capsular perforation （P = 0.02, r = 1.12）. Conclusion： The incidence of postoperative, newly reported ED after TURP was 12%. Risk factors for its occurrence were diabetes mellitus and intraoperative capsular perforation. （Asian J Androl 2006 Jan; 8： 69-74）展开更多

We conducted a retrospective analysis of clinical data of BPH patients who received PK-TURP. A total of 1126 BPH patients were divided into AUR （n = 348） and non-AUR groups （n = 778）. After the urethral catheters were removed, the urine white blood cell （WBC） count in the AUR group significantly increased compared with the non-AUR group （P〈 0.01）. However, there was no significant difference in international prostate symptom score, painful urination, and maximal urinary flow rate. The duration of hospitalization of the AUR group was longer than that of the non-AUR group （P 〈 0.001）. A total of 87.1% （303/348） patients in the AUR group and 84.1% （654/778） patients in the non-AUR group completed all of the postoperative follow-up visits. The incidence of urinary tract infection in the AUR group within 3 months after surgery was significantly higher than that in the non-AUR group （P 〈 0.01）. The incidence of temporary urinary incontinence in the AUR group did not exhibit significant difference. During 3-12 months after surgery, there were no significant differences in major complications between the two groups. Multivariate regression analyses showed that age, postvoid residual, maximal urinary flow rate, diabetes, and hypertension, but not the presence of AUR, were independent predictors of IPSS post-PK-TURP. In conclusion, immediate PK-TURP surgery on patients accompanied by AUR was safe and effective.展开更多

The bladder preservation and survival rate as well as cancer-specific survival（CSS） rate and overall survival（OS） rate of the two groups were compared.Results： Sixty-two patients were followed-up for 26-102 months with an average of 58.4±3.1 months. Recurrence-free survival（RFS） at 2-year for TUR ＋ GC group and TUR group were 77.8% and 53.8%, respectively. Bladder preserved rate（BPR） at 3-year for TUR ＋ GC group and TUR group were 94.4% and 80.8%. CSS rate at 2-year for TUR ＋ GC group and TUR group were 94.4% and 84.6%. The diseasefree survival（DFS） at 1-year for TUR ＋ GC group and TUR group were 83.3% and 61.5%, and 77.8% and 53.8% for the 2nd year. OS at 2-year for TUR ＋ GC group and TUR group were 88.9% and 92.3%.Conclusions： TUR-BT and intravesical instillation therapy combined with internal iliac artery chemotherapy for MIBC had a better outcome at RFS, BPR and DFS than the treatment without internal iliac artery chemotherapy, and no difference in OS and CSS.展开更多

This study undertaken to illustrate our initial experience LESS radical prostatectomy （RP） and analyze early outcomes. Nineteen patients diagnosed with prostate cancer underwent LESS-RP in our institute. The patients were divided into two groups： conventional LESS and transurethral assistant LESS. Preoperative, perioperative, postoperative, pathologic, and functional outcomes data were assessed. With the help of a transurethral assistant, the mean operation and anastomosis time were decreased markedly. No focal positive margins were encountered. No prostate-specific antigen recurrence was detected 1 month postoperatively. Complete continence recovery （no pad） was observed in 32% of the patients at 1 month after the operation. No intraoperative and postoperative complications were reported, LESS-RP is a feasible and effective surgical procedure for treatment of prostate cancer. Moreover, transurethral assistant LESS could reduce the difficulty of LESS-RP and shorten the operation time.展开更多

Methods： Twenty-three men with benign prostatic hyperplasia underwent both suprapubic and transurethral pressure-flow studies during a single session. Standard pressure-flow variables were recorded in all patients with both methods, enabling calculation of obstruction using commonly used grading systems, such as the urethral resistance algorithm, the Abrams-Griffith （AG） number and the Schaefer linear nomogram. Results： There were statistically significant differences between the methods in the mean values of maximum flow rate （P 〈 0.05）, detrusor pressure at the maximum flow （P 〈 0.01）, urethral resistance algorithm （P 〈 0.01）, AG number （P 〈 0.01） and maximum cystic capacity （P 〈 0.01）. Of the men in the study, 10 （43.5%） remained in the same Schaefer class with both methods and 18 （78.3%） in the same AG number area. Using the transurethral method, 12 （52.2%） men increased their Schaefer class by one and 1 （4.3%） by two. There were also differences between the suprapubic and transurethral methods using the AG number： 4 （17.4%） men moved from a classification of equivocal to obstructed and 1 （4.3%） from unobstructed to equivocal. Conclusion： The differences between the techniques for measuring intravesical pressure alter the grading of obstruction determined by several of the commonly used classifications. An 8 F transurethral catheter significantly increases the likelihood of a diagnosis of bladder outlet obstruction when compared with the suprapubic method.展开更多

Blood loss is one of the most common complications of TURP. Objective: To evaluate the effect of preoperative dutasteride on bleeding related to TURP in patients with BPH. Materials and Methods: This prospective interventional study was done in the department of urology, Dhaka Medical College Hospital, Dhaka, Bangladesh during the period of July 2016 to June 2017. A total of 70 cases of BPH planned for TURP were included in this study according to the statistical calculation. Patients were randomly allocated to control group A (TURP without dutasteride) and dutasteride group B (TURP with dutasteride). Each group consisted of 35 patients. Group B patients were treated with dutasteride 0.5 mg/day for 4 weeks before TURP. The main outcome of blood loss was evaluated in terms of reduction in serum hemoglobin (Hb) and hematocrit (Hct) levels, which were measured before and 24 hours after surgery. Data were analyzed and compared by statistical tests. Results: Comparison of outcome between groups shows that there was a significant difference in term of pre-post operative change of hemoglobin and hematocrit levels in the control group A compared to the dutasteride group B (Hb = 2.96 ± 0.80 gm/dl vs. 1.81 ± 0.71 gm/dl, respectively, p = 0.001;Hct = 11.20% ± 2.12% vs. 6.07% ± 2.02%, respectively, p = 0.02). A significant lower mean blood loss was observed in the dutasteride group compared to the control group. Conclusion: Preoperative dutasteride therapy reduces blood loss related to TURP in patients with BPH. This therapy can be practiced to reduce surgical bleeding associated with TURP.展开更多

文摘BACKGROUND Persistent suspicion of prostate cancer(PCa)due to a rising prostate-specific antigen(PSA)level after repeated negative biopsies is a serious challenge in clinical practice.AIM To determine the role of Hiraoka’s transurethral detachment of the prostate(TUDP)combined with biopsy of the peripheral zone during the same session in patients with repeated negative biopsies in the diagnosis of PCa.METHODS We retrospectively evaluated the records of 10 patients who were eligible for inclusion in our hospital between December 2012 and August 2017.Patient demographics,a family history of PCa,the number of biopsies,prostate volume,pathological examination,and perioperative PSA level were obtained.RESULTS Two of 10 patients were pathologically diagnosed with PCa after surgery;the Gleason scores were 4+4 and 4+3,respectively.Both patients subsequently underwent laparoscopic radical prostatectomy.The median PSA levels preoperatively,and 3 mo and 1 year postoperatively in the other eight patients who were diagnosed with benign prostate hyperplasia after surgery were 19.10 ng/mL,1.10 ng/mL,and 1.15 ng/mL,respectively.The adjusted P values of the 3-mo and 1-year post-operative PSA level vs pre-operative PSA level were 0.003 and 0.026,respectively.None of the patients had increased PSA levels or PCa detected after a median 35 mo of follow-up.CONCLUSION TUDP combined with peripheral zone biopsy may improve the detection rate of PCa in patients with repeated negative biopsies.The PSA level declined rapidly in patients who had negative pathological examinations after TUDP,which remained stable 1 year after surgery.
文摘BACKGROUND Transurethral columnar balloon dilatation of the prostate(TUCBDP) is a new surgical treatment, but its efficacy remains controversial because of limited clinical application.AIM To investigate the clinical effect of TUCBDP for benign prostatic hyperplasia(BPH).METHODS Overall, 140 patients with BPH who underwent surgical treatment were included in the study. A random number table was used to divide the participants into study and control groups(n = 70 per group). The study group underwent TUCBDP. The prostate resection surgical time, intraoperative blood loss, bladder irrigation time, catheter indwelling time, length of hospital stay, International Prostate Symptom Score(IPSS), maximum urine flow rate(Qmax), residual urine volume(RUV), changes in the International Erectile Function Score(ⅡEF-5) score, serum prostate-specific antigen(PSA), quality of life(QOL) score, and surgical complications were compared in both groups.RESULTS The operation time, intraoperative blood loss volume, bladder flushing time, urinary catheter indwelling time, and length of hospital stay were significantly lower in the study group than in the control group(P < 0.05). There were no significant differences in the IPSS, Qmax, and RUV measurements between the study and control groups(P > 0.05). However, at 3 mo post-surgery, the IPSS and RUV measurements were both lower(P < 0.05) and Qmax values were higher(P < 0.05) compared to the pre-surgery results in both groups. The ⅡEF-5 scores before and 3 mo after surgery were not significantly different between the study and control groups(P > 0.05). At 1 mo after surgery, the ⅡEF-5 score was higher in the study group than in the control group(P < 0.05). The serum PSA levels and QOL scores before treatment and at 1 and 3 mo after treatment were not significantly different between the study and control groups(P > 0.05). However, lower serum PSA levels and QOL scores were observed after 1 and 3 mo of treatment compared to pre-treatment levels in the study group(P < 0.05). The surgical complication rate of the study group(4.29%) was lower than that of the control group(12.86%;P < 0.05).CONCLUSION TUCBDP for BPH and transurethral resection of the prostate can achieve better results, but the former method is associated with less surgical trauma.
文摘We aim to reassess the safety of the monopolar transurethral resection of the prostate （M-TURP） without suprapubic cystostomy at our institution over the past decade. This retrospective study was conducted in patients who underwent M-TURP at Peking University First Hospital between 2003 and 2013. A total of 1680 patients who had undergone M-TURP were identified, including 539 patients in the noncystostomy group and 1141 patients in the cystostomy group. After propensity score matching, the number of patients in each group was 456. Smaller reductions in hemoglobin and hematocrit （10.9 g vs 17.6 g and 3.6% vs 4.7%, respectively） were found in the noncystostomy group. In addition, patients undergoing surgery without cystostomy had their catheters removed earlier （4.6 days vs 5.2 days）, required shorter postoperative stays in the hospital （5.1 days vs 6.0 days）, and were at lower risk of operative complications （5.7% vs 9.2%）, especially bleeding requiring blood transfusion （2.9% vs 6.1%）. Similar findings were observed in cohorts of prostates of 30-80 ml and prostates 〉80 ml. Furthermore, among patients with a resection weight 〉42.5 g or surgical time 〉90 min, or even propensity-matched patients based on surgical time, those with cystostomy seemed to be at a higher risk of operative complications. These results suggest that M-TURP without suprapubic cystostomy is a safe and effective method, even among patients with larger prostates, heavier estimated resection weights, and longer surgical times.
文摘For more than nine decades,transurethral resection of the prostate remains the gold standard for the surgical treatment of lower urinary tract symptoms due to benign prostatic obstruction.The occurrence of urethral strictures after transurethral resection of the prostate is one of the major late complications and has been reported as the leading cause of iatrogenic urethral strictures in patients older than 45 years who underwent urethroplasty.Although several postulations have been proposed to explain the urethral stricture after transurethral resection of the prostate,the exact etiology of urethral stricture after TURP is still controversial.Suggested etiological factors of urethral stricture formation after transurethral resection of the prostate include infection,mechanical trauma,prolonged indwelling catheter time,use of local anesthesia,and electrical injury by a stray current.One single treatment option is not appropriate for all stricture types.The management of urethral stricture following transurethral resection of the prostate includes minimally invasive endoscopic methods,including urethral dilation and direct visual incision,or open surgical procedures with varying urethroplasty techniques.Although scientific studies focusing on urethral strictures after transurethral resection of the prostate are relatively limited and sparse,we can apply the principles of urethral stricture management before making decisions on individual stricture treatment.
文摘The diagnosis and treatment of hemospermia presents significant difficulty, especially if it persists or recurs. In this retrospective study, we assessed whether transurethral seminal vesiculoscopy is feasible and effective in the diagnosis and treatment of hemospermia. To address this complex condition, we report our experience in a population of patients treated with transurethral seminal vesiculoscopy. From February 2006 to July 2008, 72 hemospermic patients underwent transurethral seminal vesiculoscopy examination and treatment at our urology center. Transurethral seminal vesiculoscopy was performed by a 7-F or 8-F rigid ureteroscope. The endoscopic procedure was conducted through the normal anatomic route of the seminal tracts. In this series, the mean follow-up period was 21.7 months. Definite diagnosis was made for 93.1% patients, and 94.4% patients were cured or showed a decrease in their symptoms. Postoperative complications were not observed in the study. Our study proves that transurethral seminal vesiculoscopy is effective in the diagnosis and treatment of hemospermia with minimal complication.

文摘Benign prostatic hyperplasia (BPH) is highly prevalent among older men, impacting on their quality of life, sexual function, and genitourinary health, and has become an important global burden of disease. Transurethral plasmakinetic resection of prostate (TUPKP) is one of the foremost surgical procedures for the treatment of BPH. It has become well established in clinical practice with good efficacy and safety. In 2018, we issued the guideline “2018 Standard Edition”. However much new direct evidence has now emerged and this may change some of previous recommendations. The time is ripe to develop new evidence-based guidelines, so we formed a working group of clinical experts and methodologists. The steering group members posed 31 questions relevant to the management of TUPKP for BPH covering the following areas: questions relevant to the perioperative period (preoperative, intraoperative, and postoperative) of TUPKP in the treatment of BPH, postoperative complications and the level of surgeons’ surgical skill. We searched the literature for direct evidence on the management of TUPKP for BPH, and assessed its certainty generated recommendations using the grade criteria by the European Association of Urology. Recommendations were either strong or weak, or in the form of an ungraded consensus-based statement. Finally, we issued 36 statements. Among them, 23 carried strong recommendations, and 13 carried weak recommendations for the stated procedure. They covered questions relevant to the aforementioned three areas. The preoperative period for TUPKP in the treatment of BPH included indications and contraindications for TUPKP, precautions for preoperative preparation in patients with renal impairment and urinary tract infection due to urinary retention, and preoperative prophylactic use of antibiotics. Questions relevant to the intraoperative period incorporated surgical operation techniques and prevention and management of bladder explosion. The application to different populations incorporating the efficacy and safety of TUPKP in the treatment of normal volume (< 80 ml) and large-volume (≥ 80 ml) BPH compared with transurethral urethral resection prostate, transurethral plasmakinetic enucleation of prostate and open prostatectomy;the efficacy and safety of TUPKP in high-risk populations and among people taking anticoagulant (antithrombotic) drugs. Questions relevant to the postoperative period incorporated the time and speed of flushing, the time indwelling catheters are needed, principles of postoperative therapeutic use of antibiotics, follow-up time and follow-up content. Questions related to complications incorporated types of complications and their incidence, postoperative leukocyturia, the treatment measures for the perforation and extravasation of the capsule, transurethral resection syndrome, postoperative bleeding, urinary catheter blockage, bladder spasm, overactive bladder, urinary incontinence, urethral stricture, rectal injury during surgery, postoperative erectile dysfunction and retrograde ejaculation. Final questions were related to surgeons’ skills when performing TUPKP for the treatment of BPH. We hope these recommendations can help support healthcare workers caring for patients having TUPKP for the treatment of BPH.
文摘We summarized our experience in transurethral seminal vesiculoscopy （TSV） for recurrent hemospermia by introducing surgical techniques, intraoperative findings, and treatment outcomes. TSV was performed in 419 patients with an initial diagnosis of persistent hemospermia at Shanghai Changhai Hospital （Shanghai, China） from May 2007 to November 2015. TSV was successfully performed in 381 cases （90.9%）. Hemospermia was alleviated or disappeared in 324 （85.0%） patients by 3 months after surgery. Common intraoperative manifestations were bleeding, obstruction or stenosis, mucosal lesions, and calculus. Endoscopic presentation of the ejaculatory duct orifice and the verumontanum was categorized into four types, including 8 （1.9%）, 32 （7.6%）, 341 （81.4%）, and 38 （9.1%） cases in Types A, B, C, and D, respectively. TSV is an effective and safe procedure in the management of seminal tract disorders. This study may help other surgeons to become familiar with and improve this procedure. However, further multicentric clinical trials are warranted to validate these findings.
文摘To evaluate the efficacy and safety of plasmakinetic resection of the prostate （PKRP） versus transurethral resection of the prostate （TURP） for the treatment of patients with benign prostate hyperplasia （BPH）, a meta-analysis of randomized controlled trials was carried out. We searched PubMed, Embase, Web of Science and the Cochrane Library. The pooled estimates of maximum flow rate, International Prostate Symptom Score, operation time, catheterization time, irrigated volume, hospital stay, transurethral resection syndrome, transfusion, clot retention, urinary retention and urinary stricture were assessed. There was no notable difference in International Prostate Symptom Score between TURP and PKRP groups during the 1-month, 3 months, 6 months and 12 months follow-up period, while the pooled Qmax at 1-month favored PKRP group. PKRP group was related to a lower risk rate of transurethral resection syndrome, transfusion and clot retention, and the catheterization time and operation time were also shorter than that of TURP. The irrigated volume, length of hospital stay, urinary retention and urinary stricture rate were similar between groups. In conclusion, our study suggests that the PKRP is a reliable minimal invasive technique and may anticipatoriiy prove to be an alternative electrosurgical procedure for the treatment of BPH.
文摘Aim： To identify possible risk factors for erectile dysfunction （ED） after transurethral resection of prostate （TURP） for benign prostatic hyperplasia （BPH）. Methods： Between March 1999 and March 2004, 629 patients underwent TURP in our department for the treatment of symptomatic BPH. All patients underwent transrectal ultrasound examination. In addition, the flow rate, urine residue, International Prostate Symptom Score （IPSS） and quality of life （QOL） were recorded for those who presented without a catheter. Finally, the erectile function of the patient was evaluated according to the International Index of Erectile Function Instrument （IIEF-5） questionnaire. It was determined that ED existed where there was a total score of less than 21. The flow rate, IPSS and QOL assessment were performed at 3 and 6 months post-treatment. The IIEF-5 assessment was repeated at a 6-month follow-up. A logistic regression analysis was used to identify potential risk factors for ED. Results： At baseline, 522 （83 %） patients answered the IIEF-5 questionnaire. The mean patient age was （63.7 ± 9.7） years. The ED rate was 65%. After 6 months, 459 （88%） out of the 522 patients returned the IIEF questionnaire. The rest of the group was excluded from the statistical analysis. Six months after TURP, the rate of patients reporting ED increased to 77 %. Statistical analysis revealed that the only important factors associated with newly reported ED after TURP were diabetes mellitus （P = 0.003, r = 3.67） and observed intraoperative capsular perforation （P = 0.02, r = 1.12）. Conclusion： The incidence of postoperative, newly reported ED after TURP was 12%. Risk factors for its occurrence were diabetes mellitus and intraoperative capsular perforation. （Asian J Androl 2006 Jan; 8： 69-74）
文摘In the present study, we evaluated the safety and efficacy of immediate surgical bipolar plasmakinetic transurethral resection of the prostate （PK-TURP） for patients with benign prostatic hyperplasia （BPH） with acute urinary retention （AUR）. We conducted a retrospective analysis of clinical data of BPH patients who received PK-TURP. A total of 1126 BPH patients were divided into AUR （n = 348） and non-AUR groups （n = 778）. After the urethral catheters were removed, the urine white blood cell （WBC） count in the AUR group significantly increased compared with the non-AUR group （P〈 0.01）. However, there was no significant difference in international prostate symptom score, painful urination, and maximal urinary flow rate. The duration of hospitalization of the AUR group was longer than that of the non-AUR group （P 〈 0.001）. A total of 87.1% （303/348） patients in the AUR group and 84.1% （654/778） patients in the non-AUR group completed all of the postoperative follow-up visits. The incidence of urinary tract infection in the AUR group within 3 months after surgery was significantly higher than that in the non-AUR group （P 〈 0.01）. The incidence of temporary urinary incontinence in the AUR group did not exhibit significant difference. During 3-12 months after surgery, there were no significant differences in major complications between the two groups. Multivariate regression analyses showed that age, postvoid residual, maximal urinary flow rate, diabetes, and hypertension, but not the presence of AUR, were independent predictors of IPSS post-PK-TURP. In conclusion, immediate PK-TURP surgery on patients accompanied by AUR was safe and effective.

文摘Biochemical recurrence(BCR)is important for measuring the oncological outcomes of patients who undergo radical prostatectomy(RP).Whether transurethral resection of the prostate(TURP)has negative postoperative effects on oncological outcomes remains controversial.The primary aim of our retrospective study was to determine whether a history of TURP could affect the postoperative BCR rate.We retrospectively reviewed patients with prostate cancer(PCa)who had undergone RP between January 2009 and October 2017.Clinical data on age,prostate volume,serum prostate-specific antigen levels(PSA),biopsy Gleason score(GS),metastasis stage(TNM),D’Amico classification,and American Society of Anesthesiologists(ASA)classification were collected.Statistical analyses including Cox proportional hazard models and sensitivity analyses which included propensity score matching,were performed,and the inverse-probability-of-treatment-weighted estimator and standardized mortality ratio-weighted estimator were determined.We included 1083 patients,of which 118 had a history of TURP.Before matching,the non-TURP group differed from the TURP group with respect to GS(P=0.047),prostate volume(mean:45.19 vs 36.00 ml,P<0.001),and PSA level(mean:29.41 vs 15.11 ng ml?1,P=0.001).After adjusting for age,PSA level,T stage,N stage,M stage,and GS,the TURP group showed higher risk of BCR(hazard ratio[HR]:2.27,95%confidence interval[CI]:1.13–3.94,P=0.004).After matching(ratio 1:4),patients who underwent TURP were still more likely to develop BCR according to the adjusted propensity score(HR:2.00,95%CI:1.05–3.79,P=0.034).Among patients with PCa,those with a history of TURP were more likely to develop BCR after RP.
文摘Clinical benign prostatic hyperplasia(BPH)is one of the most common cause of lower urinary tract symptoms and transurethral resection of prostate(TURP)has been the gold standard technique for surgical treatment of benign prostate obstruction(BPO)over the last 2 decades.Although monopolar TURP is considered a safe and effective option for surgical management of BPO,there are some disadvantages,namely bleeding,transurethral resection syndrome,incompleteness of treatment.This review aims to highlight these problems,and describe the advances in technology and techniques that have evolved to minimise such complications.With the advent of lasers and bipolar technology,as well as enucleative techniques to remove the prostatic adenoma/adenomata,the problems of bleeding,transurethral resection syndrome and incomplete treatment are significantly minimised.Monopolar TURPwill likely be replaced by such technology and techniques in the near future such that transurethral surgery of the prostate remain a safe and effective option in alleviating the harmful effects of BPO.
文摘Objective： To evaluate the clinical effect of transurethral resection of bladder tumor（TUR-BT） combined with internal iliac artery chemotherapy and intravesical instillation therapy for muscle invasive bladder cancer（MIBC）.Methods： From February 2007 to April 2014, 62 patients with MIBC were treated with TUR-BT combined with intravesical instillation therapy, with or without internal iliac artery chemotherapy, and the chemotherapy regimen is gemcitabine and cisplatin（GC）. The bladder preservation and survival rate as well as cancer-specific survival（CSS） rate and overall survival（OS） rate of the two groups were compared.Results： Sixty-two patients were followed-up for 26-102 months with an average of 58.4±3.1 months. Recurrence-free survival（RFS） at 2-year for TUR ＋ GC group and TUR group were 77.8% and 53.8%, respectively. Bladder preserved rate（BPR） at 3-year for TUR ＋ GC group and TUR group were 94.4% and 80.8%. CSS rate at 2-year for TUR ＋ GC group and TUR group were 94.4% and 84.6%. The diseasefree survival（DFS） at 1-year for TUR ＋ GC group and TUR group were 83.3% and 61.5%, and 77.8% and 53.8% for the 2nd year. OS at 2-year for TUR ＋ GC group and TUR group were 88.9% and 92.3%.Conclusions： TUR-BT and intravesical instillation therapy combined with internal iliac artery chemotherapy for MIBC had a better outcome at RFS, BPR and DFS than the treatment without internal iliac artery chemotherapy, and no difference in OS and CSS.

文摘Enhanced recovery after surgery(ERAS)measures have not been systematically applied in transurethral surgery for benign prostatic hyperplasia(BPH).This study was performed on patients with BPH who required surgical intervention.From July 2019 to June 2020,the ERAS program was applied to 248 patients,and the conventional program was applied to 238 patients.After 1 year of follow-up,the differences between the ERAS group and the conventional group were evaluated.The ERAS group had a shorter time of urinary catheterization compared with the conventional group(mean±standard deviation[s.d.]:1.0±0.4 days vs 2.7±0.8 days,P<0.01),and the pain(mean±s.d.)was significantly reduced through postoperative hospitalization days(PODs)0-2(POD 0:1.7±0.8 vs 2.4±1.0,P<0.01;POD 1:1.6±0.9 vs 3.5±1.3,P<0.01;POD 2:1.2±0.7 vs 3.0±1.3,P<0.01).No statistically significant difference was found in the rate of postoperative complications,such as postoperative bleeding(P=0.79),urinary retention(P=0.40),fever(P=0.55),and readmission(P=0.71).The hospitalization cost of the ERAS group was similar to that of the conventional group(mean±s.d.:16927.8±5808.1 Chinese Yuan[CNY]vs 17044.1±5830.7 CNY,P=0.85).The International Prostate Symptom Scores(IPSS)and quality of life(QoL)scores in the two groups were also similar when compared at 1 month,3 months,6 months,and 12 months after discharge.The ERAS program we conducted was safe,repeatable,and efficient.In conclusion,patients undergoing the ERAS program experienced less postoperative stress than those undergoing the conventional program.
文摘The laparoendoscopic single-site （LESS） technique is the latest technical innovation in laparoscopic surgery to undergo exponential development in urology. This study undertaken to illustrate our initial experience LESS radical prostatectomy （RP） and analyze early outcomes. Nineteen patients diagnosed with prostate cancer underwent LESS-RP in our institute. The patients were divided into two groups： conventional LESS and transurethral assistant LESS. Preoperative, perioperative, postoperative, pathologic, and functional outcomes data were assessed. With the help of a transurethral assistant, the mean operation and anastomosis time were decreased markedly. No focal positive margins were encountered. No prostate-specific antigen recurrence was detected 1 month postoperatively. Complete continence recovery （no pad） was observed in 32% of the patients at 1 month after the operation. No intraoperative and postoperative complications were reported, LESS-RP is a feasible and effective surgical procedure for treatment of prostate cancer. Moreover, transurethral assistant LESS could reduce the difficulty of LESS-RP and shorten the operation time.
文摘Objective： To observe the advantage of total intravenous anesthesia for transurethral resection of bladder tumor （TURBT）. Methods.. Sixty ASA Ⅰ-Ⅱ patients undergoing TURBT were randomly assigned to 2 groups. Spinal anesthesia with 0. 75% pure bupivacaine （8-12 rag） was applied to patients in Group Ⅰ （n= 30）. Patients in Group Ⅱ （n=30） received total intravenous anesthesia with continuous infusion of Propofol and Remifentanil ; and a laryngeal mask was used to ensure the airway and ventilation. BP, HR, SPO2 and pertinent side effects were monitored and recorded. Results ： The patients in group Ⅱ experienced more stable hemodynamics than those in group Ⅰ . Obturator nerve reflex was observed in 15 （50. 0%） patients in Group Ⅰ , but none （0%） in Group Ⅱ （P〈0. 01）. Conclusion.. Total intravenous anesthesia with laryngeal mask is a safe, reliable, controllable and simple manual for patient undergoing TURBT.
文摘Aim： To compare the use of the suprapubic puncture method versus the transurethral method in pressure-flow studies in patients with benign prostatic hyperplasia. Methods： Twenty-three men with benign prostatic hyperplasia underwent both suprapubic and transurethral pressure-flow studies during a single session. Standard pressure-flow variables were recorded in all patients with both methods, enabling calculation of obstruction using commonly used grading systems, such as the urethral resistance algorithm, the Abrams-Griffith （AG） number and the Schaefer linear nomogram. Results： There were statistically significant differences between the methods in the mean values of maximum flow rate （P 〈 0.05）, detrusor pressure at the maximum flow （P 〈 0.01）, urethral resistance algorithm （P 〈 0.01）, AG number （P 〈 0.01） and maximum cystic capacity （P 〈 0.01）. Of the men in the study, 10 （43.5%） remained in the same Schaefer class with both methods and 18 （78.3%） in the same AG number area. Using the transurethral method, 12 （52.2%） men increased their Schaefer class by one and 1 （4.3%） by two. There were also differences between the suprapubic and transurethral methods using the AG number： 4 （17.4%） men moved from a classification of equivocal to obstructed and 1 （4.3%） from unobstructed to equivocal. Conclusion： The differences between the techniques for measuring intravesical pressure alter the grading of obstruction determined by several of the commonly used classifications. An 8 F transurethral catheter significantly increases the likelihood of a diagnosis of bladder outlet obstruction when compared with the suprapubic method.
文摘It is largely unknown whether lower urinary tract symptoms(LUTS)or acute retention of urine(AROU)is linked to shorter life expectancy in men.We conducted a multicenter,retrospective database analysis of patients undergoing transurethral resection of prostate(TURP)to study their relationships.Multivariate Cox regression analysis and Kaplan-Meier analysis with stratification to age and indication of TURP were performed.We further performed an age-and sex-matched survival analysis with the general population using data from the Census and Statistics Department of the Hong Kong Special Administrative Region(Hong Kong,China).From January 2002 to December 2012,3496 patients undergoing TURP were included in our study,with 1764 patients in the LUTS group and 1732 patients in the AROU group.Old age,ischemic heart disease,cerebrovascular accident,and AROU were risk factors of mortality.Patients aged<70 years(adjusted hazard ratio[HR]:1.52,95%confidence interval[Cl]:1.11-2.09,P=0.010)and 70-80 years(adjusted HR:1.39,95%Cl:1.15-1.70,P-0.001)in the AROU group had worse survival than those in the LUTS group,but such difference was not demonstrated in patients aged>80 years.Compared to the general population,younger patients in the LUTS group appeared to have better survival(<70 years,P=0.091;70-80 years,P=0.011),but younger patients in the AROU group had worse survival(<70 years,P=0.021;70-80 years,P=0.003).For patients aged>80 years,survival was similar with the general population in both the LUTS and AROU groups.In conclusion,AROU at young age was associated with mortality,while early detection and management of LUTS may improve survival.
文摘Background: Transurethral resection of prostate (TURP) is the gold standard in the surgical treatment of symptomatic benign prostatic hyperplasia (BPH). Blood loss is one of the most common complications of TURP. Objective: To evaluate the effect of preoperative dutasteride on bleeding related to TURP in patients with BPH. Materials and Methods: This prospective interventional study was done in the department of urology, Dhaka Medical College Hospital, Dhaka, Bangladesh during the period of July 2016 to June 2017. A total of 70 cases of BPH planned for TURP were included in this study according to the statistical calculation. Patients were randomly allocated to control group A (TURP without dutasteride) and dutasteride group B (TURP with dutasteride). Each group consisted of 35 patients. Group B patients were treated with dutasteride 0.5 mg/day for 4 weeks before TURP. The main outcome of blood loss was evaluated in terms of reduction in serum hemoglobin (Hb) and hematocrit (Hct) levels, which were measured before and 24 hours after surgery. Data were analyzed and compared by statistical tests. Results: Comparison of outcome between groups shows that there was a significant difference in term of pre-post operative change of hemoglobin and hematocrit levels in the control group A compared to the dutasteride group B (Hb = 2.96 ± 0.80 gm/dl vs. 1.81 ± 0.71 gm/dl, respectively, p = 0.001;Hct = 11.20% ± 2.12% vs. 6.07% ± 2.02%, respectively, p = 0.02). A significant lower mean blood loss was observed in the dutasteride group compared to the control group. Conclusion: Preoperative dutasteride therapy reduces blood loss related to TURP in patients with BPH. This therapy can be practiced to reduce surgical bleeding associated with TURP.
文摘Objective:Transurethral resection of bladder tumor is one of the most common everyday urological procedures.This kind of surgery demands a set of skills that need training and experience.In this review,we aimed to investigate the current literature to find out if simulators,phantoms,and other training models could be used as a tool for teaching urologists.Methods:A systematic review was performed according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses statement and the recommendations of the European Association of Urology guidelines for conducting systematic reviews.Fifteen out of 932 studies met our inclusion criteria and are presented in the current review.Results:The UroTrainer(Karl Storz GmbH,Tuttlingen,Germany),a virtual reality training simulator,achieved positive feedback and an excellent face and construct validity by the participants.The inspection of bladder mucosa,blood loss,tumor resection,and procedural time was improved after the training,especially for inexperienced urologists and medical students.The construct validity of UroSim®(VirtaMed,Zurich,Switzerland)was established.SIMBLA simulator(Samed GmbH,Dresden,Germany)was found to be a realistic and useful tool by experts and urologists with intermediate experience.The test objective competency model based on SIMBLA simulator could be used for evaluating urologists.The porcine model of the Asian Urological Surgery Training and Education Group also received positive feedback by the participants that tried it.The Simulation and Technology Enhanced Learning Initiative Project had an extraordinary face and content validity,and 60%of participants would like to use the simulators in the future.The 5-day multimodal training curriculum“Boot Camp”in the United Kingdom achieved an increase of the level of confidence of the participants that lasted months after the project.Conclusion:Simulators and courses or curricula based on a simulator training could be a valuable learning tool for any surgeon,and there is no doubt that they should be a part of every urologist's technical education.
