Methods： The authors analysed repair figures and possible causes of damage to 35 instruments sent for repair to a leading UK supplier over a 1-year period, and calculated cost figures for maintenance of the instruments as opposed to repair and replacement costs. Results： All damages were handling-induced and therefore did not fall under the manufacturer＇s warranty： 28 % were damaged by misfiring of the laser inside the instrument; 72 %, mainly crushing and stripping of the ureteroscope shaft tube, were likely to have occurred during out-of-surgery handling, washing and disinfection. Seventeen （4 %） instruments were not repaired and consequently taken out of service due to the extensive costs involved. Eighteen （51%） ureteroscopes were repaired at an average cost of 10 833 USD. Conclusion： Damages to flexible ureteroscopes bear considerable costs. Most damages occur during handling between surgical procedures. Thorough adherence to handling procedures, and courses for theater staff and surgeons on handling flexible instruments may help to reduce these damages and prove a cost-saving investment. The authors provide a list of recommended procedural measures that may help to prevent such damages.展开更多

Clinical data including operation time, lithotripsy time, complications and stone-free rate were analyzed retrospectively. Our study showed that the percutaneous renal access （F14-F18） was successfully established under B-ultrasound guidance in all cases. Immediate phase Ⅰ lithotripsy was performed in 47 cases through single tract, and in one case through two tracts. Delayed phase Ⅱ lithotripsy was done in 5 cases of renal stones. Operation time ranged from 55 to 180 rain with an average time of 100±15 min. Lithotripsy time was from 25 to 135 min and the average lithotripsy time was 65±11 min. No severe complications occurred in our series. Complex renal stones were cleared in 34 of 38 cases （89.5 %）. All ureteral stones were completely removed in 15 cases （100 %）. It was concluded that mini-percutaneous nephrolithotomy with Nd：YAG laser for the treatment of upper urinary tract stones by combination of rigid ureteroscope and flexible ureteroscope has the advantages of effectiveness, mini-invasion, shorter operative time and safety.展开更多

Patients and Methods: This study was conducted from October 2017 to March 2019 in Department of General Surgery, Maulana Azad Medical College, New Delhi. 30 patients (out of which 6 were excluded due to spontaneous passage of calculus), with single lower ureteric calculus were chosen and the outcome of URSL was compared with respect to CT parameters of Size, HU and Hydronephrosis and intra-operative clearance of calculus. Results: Success rate of URSL in single lower ureteric calculus was found to be 75%. Lower HU (774.12 ± 212.85) was associated with higher success rate. Similarly smaller size of calculus (9 ± 2.1) mm was associated with success group. Patients with gross hydronephrosis had a poor outcome of URSL. Lower urinary tract infection (8.33%) was the most common complication. Conclusion: Patients with small size calculus, low HU and absence of hydronephrosis have a better outcome of URSL.展开更多

Methods: Eligible studies were identified from electronic databases. Database search, quality assessment, and data extraction were performed by two reviewers independently. Our primary outcome was the stone-free rate. Secondary outcomes were the fragmentation rate, complications and the rate of re-treatment and secondary procedures. The results were assessed by Review Manager 5.0. Publication bias was evaluated by Stata 11.0. Results: 13 trials were included. Meta-analysis of pooled data showed that pneumatic ureteroscopic lithotripsy demonstrated a significant advantage over extracorporeal shock wave lithotripsy (OR = 0.14, 95% CI [0.09, 0.23], P < 0.00001) in the stone-free rate;the extracorporeal shock wave lithotripsy had statistical disadvantages over pneumatic ureteroscopic lithotripsy in the fragmentation rate of ureteral stones (OR = 0.14, 95% CI [0.05, 0.39], P = 0.0002);and the rate of re-treatment and secondary procedure was lower in pneumatic ureteroscopic lithotripsy than in extracorporeal shock wave lithotripsy (OR = 5.37, 95% CI [2.61, 11.07], P < 0.00001). Our pooled results showed that there was no statistical difference between extracorporeal shock wave lithotripsy and pneumatic ureteroscopic lithotripsy in hematuresis, ureteral stricture and urosepsis or fever. Finally extracorporeal shock wave lithotripsy had a higher incidence of colic pain than pneumatic ureteroscopic lithotripsy. Conclusion: The present meta-analysis suggested that pneumatic ureteroscopic lithotripsy had large advantages over extracorporeal shock wave lithotripsy in the treatment of lower ureteral stones.展开更多

Methods: 160 urology patients from January 2017 to January 2020 were 80 patients with ureteral stones of 2 to 3 cm, 80 patients (n80) and VAS80) before and after surgery, including renal function, change in infection index, pain visual simulation score (VAS). Conclusions: the 2dBUN, PCT and MPCNL groups after the P U R S L group (P <0.05) were lower than the MPCNL group (P <0.05). The postoperative 2dBUN and PCT groups (P <0.05) were all lower than those in the MPCNL group (P <0.05). The postoperative 2dBUN, PCT, and PCT groups (P <0.05) were all lower than those in the MPCNL group (P <0.05). In the PCT group, the postoperative 2dBUN, PCT, and PCT group (P <0.05) were all lower than those in the MPCNL group (P <0.05). No postoperative 2dBUN, PCT and PCT groups (P <0.05) (P <0.05);After surgery of the FURSL group, the 2dBUN, PCT and PCT group (P <0.05) were all lower than those of the MPCNL group (P <0.05). None of the results were statistically significant. The ureteroscopic holmium laser lithotripsy group applied natural cavity technology without surgical incision, which causes small harm to the patient, the patient recovers quickly after the operation, will not cause serious kidney damage, and the patient need not bear severe pain after surgery, and the chance of complications is relatively low. Compared with minimally invasive percutaneous nephrolithotripsy, the time will be longer for 2 to 3 cm, and the first surgical stone clearance is lower than that of minimally invasive percutaneous nephrolithotripsy. The time of treatment should also be determined by the state of the patients condition.展开更多

Methods: the study began in January 2020 and ended in November 2021. Forty-eight patients who came to the hospital for treatment during the study period were selected as the research objects. All of them were hospitalized for upper urinary tract stones. They were divided into two different groups by random drawing of lots. They were named as the contrast group and the observation group, with 24 patients in each group. Holmium laser lithotripsy with flexible ureteroscope was used as the treatment between the two groups. The former received surgical treatment while carrying out routine care, while the latter carried out comprehensive care. The nursing effect between the groups was compared and analyzed. Results: compared with the two groups, the operation index of the observation group was better (p < 0.05). The clinical indexes of the observation group improved more (P < 0.05). The observation group had a relatively lower incidence of complications and higher nursing satisfaction (P < 0.05). In terms of quality of life, the observation group improved better (P < 0.05). Conclusion: in the process of implementing ureteroscopic holmium laser lithotripsy for patients with upper urinary tract calculi, combined with comprehensive nursing intervention can produce a relatively ideal intervention effect, which is suitable for universal use.展开更多

Methods: 84 patients with isolated renal kidney calculi in this study were randomly selected from 2018/1 to 2020/1 and divided into two groups. One group was the control group treated with percutaneous nephrolithotomy (n=42) and the other group was the experimental group treated with ureteroscopic holmium laser lithotripsy (n=42). The operation conditions and prognosis indexes of the two groups were evaluated. Results: through the clinical treatment using the "laser lithotripsy" technique of flexible ureteroscope holmium, aiming at the patients in the experimental group, the operation process will lead to intraoperative blood loss, and effectively control the operation time, hospital stay time and relevant index value of catheter indwelling time set by laser lithotripsy during the operation. The observation group is obviously better than the control group using percutaneous nephroscope treatment (P < 0.05), but the first-stage stone removal rate of the experimental group is not different from that of the control group (P > 0.05). Conclusion: for kidney calculi patients with "isolated kidney" before operation, laser lithotripsy with special clinical treatment of "flexible ureteroscope and holmium" is adopted during the treatment, and the treatment effect is significant in stone removal. The operation time is short, the postoperative recovery is fast, and the hospitalization time is short, which reduces the economic burden for patients and is helpful for popularization.展开更多
文摘Aim： To investigate the causes and costs of flexible ureteroscope damage, and to develop recommendations to limit damage. Methods： The authors analysed repair figures and possible causes of damage to 35 instruments sent for repair to a leading UK supplier over a 1-year period, and calculated cost figures for maintenance of the instruments as opposed to repair and replacement costs. Results： All damages were handling-induced and therefore did not fall under the manufacturer＇s warranty： 28 % were damaged by misfiring of the laser inside the instrument; 72 %, mainly crushing and stripping of the ureteroscope shaft tube, were likely to have occurred during out-of-surgery handling, washing and disinfection. Seventeen （4 %） instruments were not repaired and consequently taken out of service due to the extensive costs involved. Eighteen （51%） ureteroscopes were repaired at an average cost of 10 833 USD. Conclusion： Damages to flexible ureteroscopes bear considerable costs. Most damages occur during handling between surgical procedures. Thorough adherence to handling procedures, and courses for theater staff and surgeons on handling flexible instruments may help to reduce these damages and prove a cost-saving investment. The authors provide a list of recommended procedural measures that may help to prevent such damages.
文摘Objective:Single-use flexible ureteroscopes(fURSs)have recently been introduced by different companies.Goal of this in-vitro study was to compare four fURSs.Methods:We performed in vitro analysis of Uscope 7.5 Fr and Uscope 9.5 Fr(Pusen Ltd.,Zhuhai,China),LithoVue 9.5 Fr(LithoVue,Boston Scientific,MA,USA),and Indoscope 9.5 Fr(Bioradmedisys,Pune,India).Optical characteristics(image resolution,color representation,and luminosity)were compared at various distances of 10 mm,20 mm,and 50 mm.Deflection and irrigation were evaluated with and without accessories.Results:Color perception was comparable for all scopes at 10 mm(p<0.05),while Lithovue 9.5 Fr was comparable with Indoscope 9.5 Fr at the distances of 20 mm and 50 mm.Both scopes were statistically better than both Uscopes at the distances of 20 mm and 50 mm.Image resolution powers were comparable amongst all fURSs at the distances of 10 mm and 20 mm(3.56 line pairs per millimeter[lp/mm]).However,Indoscope(3.56 lp/mm)was superior to LithoVue and Uscope scopes(3.17 lp/mm)at the distance of 50 mm.Luminosity at the distance of 10 mm was comparable for LithoVue and Uscope 9.5 Fr.However,at the distances of 20 mm and 50 mm,LithoVue had the highest luminosity while Uscope 7.5 Fr had the lowest one.Indoscope had lower luminosity than other 9.5 Fr scopes at all distances.With empty working channel and 200 mm laser fiber,Indoscope had the maximum deflection(285).With basket,Uscope 7.5 Fr had the maximum loss of deflection(30)while Indoscope had no deflection loss.With empty working channel,all scopes had comparable irrigation flow rates in both deflected and undeflected state.Similarly,with 200 mm laser or basket,irrigation flow rates were comparable in all scopes.Conclusion:Color representation was equivalent for Indoscope and LithoVue,while being better than Uscope 7.5 Fr and Uscope 9.5 Fr.Image resolution was comparable in all scopes at the distances of 10 mm and 20 mm.Beyond the distance of 10 mm,luminosity of LithoVue was the highest and that of Uscope 7.5 Fr was the lowest.Deflection loss was the minimum with Indoscope and the maximum with 7.5 Fr Uscope.Under all scenarios,irrigation flow rates were comparable in all scopes.
文摘Objective:To analyze the effect of Shiwei Powder combined with stone composition analysis on stone removal efficiency and complication rates after ureteroscopic holmium laser lithotripsy(FURL).Methods:Ninety six patients with FURL admitted to the hospital from March 2023 to March 2025 were selected and randomly divided into two groups.The observation group was treated with FURL combined with Shiwei Powder,while the control group was treated with FURL monotherapy.Based on the stone composition of the two groups,the stone removal efficiency,complication rates,recurrence rates,TCM syndrome scores,and inflammatory factor levels were compared.Results:The stone removal efficiency of the observation group was higher than that of the control group.The stone composition was mainly calcium oxalate monohydrate and composite stones containing calcium oxalate monohydrate.The incidence of postoperative complications was lower in the observation group than in the control group(P<0.05).After 3–6 months of follow-up,the recurrence rate in the observation group was lower than that in the control group(P<0.05).After treatment,the TCM syndrome scores and inflammatory factor levels in the observation group were lower than those in the control group(P<0.05).Conclusion:Based on the results of urinary stone composition analysis,patients treated with Shiwei Powder after FURL have higher stone removal efficiency.The most significant effect is observed in urinary stones composed of calcium oxalate monohydrate and composite stones containing calcium oxalate monohydrate.This treatment can improve stone removal,prevent complications,reduce recurrences,effectively improve disease symptoms,and reduce inflammation.

文摘To observe the efficacy and safety of mini-percutaneous nephrolithotomy with Neodymium：Yttrium Aluminum Garnet （Nd-YAG） laser in the treatment for upper urinary tract stones, from December 2005 to September 2006, 31 patients with renal stones, 15 patients with ureteral stones and 7 patients with renal and ureteral stones underwent mini-percutaneous nephrolithotomy with Nd-YAG laser by combination of rigid ureteroscope and flexible ureteroscope under B-ultrasound guidance. Clinical data including operation time, lithotripsy time, complications and stone-free rate were analyzed retrospectively. Our study showed that the percutaneous renal access （F14-F18） was successfully established under B-ultrasound guidance in all cases. Immediate phase Ⅰ lithotripsy was performed in 47 cases through single tract, and in one case through two tracts. Delayed phase Ⅱ lithotripsy was done in 5 cases of renal stones. Operation time ranged from 55 to 180 rain with an average time of 100±15 min. Lithotripsy time was from 25 to 135 min and the average lithotripsy time was 65±11 min. No severe complications occurred in our series. Complex renal stones were cleared in 34 of 38 cases （89.5 %）. All ureteral stones were completely removed in 15 cases （100 %）. It was concluded that mini-percutaneous nephrolithotomy with Nd：YAG laser for the treatment of upper urinary tract stones by combination of rigid ureteroscope and flexible ureteroscope has the advantages of effectiveness, mini-invasion, shorter operative time and safety.
文摘Objective: To evaluate the outcome of ureteroscopic pneumatic lithotripsy in single lower ureteric calculus and correlate its success with different CT parameters like HU, size of calculus and hydrnephrosis, if present. Patients and Methods: This study was conducted from October 2017 to March 2019 in Department of General Surgery, Maulana Azad Medical College, New Delhi. 30 patients (out of which 6 were excluded due to spontaneous passage of calculus), with single lower ureteric calculus were chosen and the outcome of URSL was compared with respect to CT parameters of Size, HU and Hydronephrosis and intra-operative clearance of calculus. Results: Success rate of URSL in single lower ureteric calculus was found to be 75%. Lower HU (774.12 ± 212.85) was associated with higher success rate. Similarly smaller size of calculus (9 ± 2.1) mm was associated with success group. Patients with gross hydronephrosis had a poor outcome of URSL. Lower urinary tract infection (8.33%) was the most common complication. Conclusion: Patients with small size calculus, low HU and absence of hydronephrosis have a better outcome of URSL.
文摘Objective:Double-J(DJ)ureteric stents are commonly placed perioperatively for semirigid or flexible ureteroscopic renal surgery.It is believed that lesser stent material within the bladder mitigates stent-related symptoms.This study aimed to evaluate the J-Fil ureteral stent,a single pigtail suture stent compared with conventional DJ stent in relation to stent symptoms in an Asian population undergoing ureterorenal intervention.Methods:Based on internal audit committee recommendation approval,the records of 50 patients retrieved,available data of 41 patients who were prospectively enrolled into two groups(Group 1[J-Fil stent group],n=21 and Group 2[DJ stent group],n=20)between August 2020 to January 2021,were analysed.Parameters compared were nature of procedure,stone location and size,ease of deployment or removal,and complications.A modified universal stent symptom questionnaire was used to assess morbidity of stent symptoms within 48 h of insertion and at removal.Results:Both groups had similar median age,distribution in male to female ratio,and stone size.The overall median universal stent symptom questionnaire score at insertion was similar for bladder pain,flank or loin pain,and quality of life between Group 1 and 2;however,at removal Group 1 fared significantly better than Group 2,especially for flank or loin pain and pain at voiding.Both groups had similar ease in insertion with no hospital readmissions.Conclusion:Our audit favoured the single pigtail suture stent in Asian ureters in mitigating stent-related issues.It showed a good safety profile with easy deployment and removal.It promises a new standard in stenting.
文摘Objective: To assess the efficacy and safety of extracorporeal shock wave lithotripsy or pneumatic ureteroscopic lithotripsy for lower ureteral stones therapy, we sought to identify and summarize randomized controlled trials that were used to treat distal ureteral stone. Methods: Eligible studies were identified from electronic databases. Database search, quality assessment, and data extraction were performed by two reviewers independently. Our primary outcome was the stone-free rate. Secondary outcomes were the fragmentation rate, complications and the rate of re-treatment and secondary procedures. The results were assessed by Review Manager 5.0. Publication bias was evaluated by Stata 11.0. Results: 13 trials were included. Meta-analysis of pooled data showed that pneumatic ureteroscopic lithotripsy demonstrated a significant advantage over extracorporeal shock wave lithotripsy (OR = 0.14, 95% CI [0.09, 0.23], P < 0.00001) in the stone-free rate;the extracorporeal shock wave lithotripsy had statistical disadvantages over pneumatic ureteroscopic lithotripsy in the fragmentation rate of ureteral stones (OR = 0.14, 95% CI [0.05, 0.39], P = 0.0002);and the rate of re-treatment and secondary procedure was lower in pneumatic ureteroscopic lithotripsy than in extracorporeal shock wave lithotripsy (OR = 5.37, 95% CI [2.61, 11.07], P < 0.00001). Our pooled results showed that there was no statistical difference between extracorporeal shock wave lithotripsy and pneumatic ureteroscopic lithotripsy in hematuresis, ureteral stricture and urosepsis or fever. Finally extracorporeal shock wave lithotripsy had a higher incidence of colic pain than pneumatic ureteroscopic lithotripsy. Conclusion: The present meta-analysis suggested that pneumatic ureteroscopic lithotripsy had large advantages over extracorporeal shock wave lithotripsy in the treatment of lower ureteral stones.
文摘Objective Ureteral lesions caused by impacted ureteral stones are likely to result in postoperative ureteral stricture.On this basis,the study aimed to investigate if dual-energy spectral computed tomography can predict ureteral hardening caused by impacted stones and to explore the relationship between different types of ureteral lesions and the risk of ureteral stricture.Methods This prospective study collected data of 93 patients with impacted stones from hospital automation system during January 2018 to October 2019.They underwent an abdominal scan on a dual-energy spectral computed tomography.During surgery,the operator used ureteroscopy to identify ureteral lesions,which were classified into four categories:edema,polyps,pallor,and hardening.Seven months later,90 patients were reviewed for the degree of hydronephrosis.Results Endoscopic observations revealed 38(41%)cases of ureteral edema,20(22%)cases of polyps,13(14%)cases of pallor,and 22(24%)cases of hardening.There were significant differences in hydronephrosis,the period of impaction,the calcium concentration of the ureter,and the slope of the spectral Hounsfield unit curve between the four groups.After that,we evaluated the factors associated with ureteral hardening and found that the calcium concentration of the ureter and hydronephrosis remained independent predictors of ureteral hardening.Receiver operating characteristic curve analysis showed that 5.3 mg/cm^(3)calcium concentration of the ureter is an optimal cut-off value to predict ureteral hardening.The result of follow-up showed that 80 patients had complete remission of hydronephrosis,with a complete remission rate of 61.9%(13/21)in the hardening group and 97.1%(67/69)in the non-hardening group(p<0.001).Conclusion Calcium concentration of the ureter is an independent predictor of ureteral hardening.Patients with ureteral hardening have more severe hydronephrosis after ureteroscopic lithotripsy.When the calcium concentration of the ureter is less than 5.3 mg/cm^(3),ureteral lesions should be actively treated.

文摘BACKGROUND Drainage tube removal is difficult when the greater omentum becomes incarcerated in the drainage tube through the side holes.Currently,known removal methods are either ineffective or will cause additional damage to the patient in a secondary operation.Ureteroscopy and the holmium laser have been used in various surgical techniques in urology,and in theory,they are expected to be a good strategy for solving the problem of tissue incarceration.CASE SUMMARY Four patients diagnosed with difficult removal of an abdominal drainage tube following abdominal surgery are reported.All patients underwent surgery to remove the incarcerated greater omentum in the drainage tube using a holmium laser and a ureteroscope,and a new 16-F drain was then placed in the abdominal or pelvic cavity.The efficacy of this technique was evaluated by intraoperative conditions,success rate,and operating time;safety was evaluated by perioperative conditions and the probability of postoperative complications.All four operations went smoothly,and the drains were successfully removed in all patients.The average operating time was 24.5 min.Intraoperatively,the average irrigation volume was 892.0 mL,the average drainage volume was 638.5 mL,and no bleeding or damage to surrounding tissues was observed.Postoperatively,the average drainage volume was 32.8 mL and the new drains were removed within 36 h.All patients were able to get out of bed and move around within 12 h.Their visual analogue pain scores were all below 3.The average follow-up duration was 12.5 mo and no complications such as fever or bleeding were noted.CONCLUSION Ureteroscopic holmium laser surgery is an effective,safe and minimally invasive technique for removing drains where the greater omentum is incarcerated in the abdominal drain.
文摘BACKGROUND Urothelial encrusted pyelo-ureteritis disease is an infrequent condition and there is no unified surgical treatment and reference standard to consult.We have used a minimally invasive endoscopic method to treat three such cases,which yielded excellent results.CASE SUMMARY The first case was a 45-year-old man who had unilateral ureteropelvic junction(UPJ)atresia and contralateral stenosis and was treated by double endoscopic surgery using an anterograde percutaneous nephroscope coupled with a rigid retrograde ureteroscope.The second case was a 12-year-old boy who received a percutaneous nephroscopy on one side and a percutaneous nephroscopy with a rigid ureteroscope on the other side due to the presence of bilateral UPJ stenosis.The third case was a 32-year-old woman with bilateral lower ureteral stricture treated using a rigid retrograde ureteroscope.Endoscopic surgeries were successfully performed on all the three patients.Varying degrees of encrustation and erosion of the urothelium were observed during the operation.The calcified layer composition analysis showed magnesium ammonium phosphate or carbonate apatite.Two patients achieved a good prognosis.CONCLUSION Minimally invasive endoscopic treatment for urothelial encrusted pyelo-ureteritis disease can yield better results.

Methods: A total of 97 cases of renal calculi patients were chosen as the research objects, based on the random data table, they were divided into the control group (n=49) and the observation group (n=48), patients in the control group underwent percutaneous nephrolithotomy (PCNL) treatment, while the observation group patients were treated with flexible ureteroscope lithotripsy (FURL), before and after 1 d ,the levels of inflammatory factors [interleukin-10 (IL-10), C reactive protein (CRP), white blood cell (WBC)], stress hormone [cortisol (COR), adrenocorticotropic hormone (ACTH), norepinephrine (NE)] and oxidative stress [malondialdehyde (MDA), superoxide dismutase (SOD) ] of the two groups were compared. Results: There were no significant differences in IL-10, CRP, WBC, COR, ACTH, NE, MDA and SOD levels between the two groups preoperative;Compared with the preoperative level in the group, the 1 d post-operation levels of IL-10, CRP, WBC, COR, ACTH, NE and MDA in the two groups were significantly increased, and the level of the observation group was significantly lower than that in the control group;The levels of SOD in the two groups 1 d post-operation were significantly lower than those in the same group preoperative, and the control group (85.65±9.95) U/mL was significantly lower than that of the control group (94.71±7.63) U/mL. Conclusion: Compared with percutaneous nephrolithotomy, flexible ureteroscopic lithotripsy for renal calculi is less stressful and more favorable for postoperative recovery, has an important clinical value.
文摘Objective: to analyze the operation and nursing methods of ureteroscopic pneumatic lithotripsy for urethral calculi. Methods: a total of 120 patients who were treated for urethral calculi in our hospital in 2021 were randomly divided into observation group and control group, with 60 patients in each group. Both groups of patients will be treated with pneumatic lithotripsy under ureteroscope after entering our hospital. Patients in the observation group will receive comprehensive care, while those in the control group will receive general care. After the treatment, the operation, nursing satisfaction, postoperative complications and hospitalization of the two groups were compared. Results: the observation group showed more advantages in operation and nursing satisfaction. Conclusion: patients suffering from urethral calculi and receiving pneumatic lithotripsy under ureteroscope should use more advanced comprehensive care and the final treatment effect will be better, which is worth popularizing.

The primary stone clearance rate in the observation group was higher than that in the control group (P < 0.05), and the intraoperative stone escape rate, postoperative fever incidence and postoperative septic shock incidence in the observation group were significantly lower than those in the control group (P < 0.05), with statistically significant differences. Conclusion: the self-made negative pressure suction device combined with URL can significantly reduce the intraoperative calculus escape rate and the incidence of septic shock, and can significantly improve the primary calculus clearance rate with good effect.
文摘Objective: to study the efficacy of ureteroscopic holmium laser lithotripsy (FURSL) and minimally invasive percutaneous nephrolithotripsy (MPCNL) in the treatment of 2 to 3 cm kidney stones. Methods: 160 urology patients from January 2017 to January 2020 were 80 patients with ureteral stones of 2 to 3 cm, 80 patients (n80) and VAS80) before and after surgery, including renal function, change in infection index, pain visual simulation score (VAS). Conclusions: the 2dBUN, PCT and MPCNL groups after the P U R S L group (P <0.05) were lower than the MPCNL group (P <0.05). The postoperative 2dBUN and PCT groups (P <0.05) were all lower than those in the MPCNL group (P <0.05). The postoperative 2dBUN, PCT, and PCT groups (P <0.05) were all lower than those in the MPCNL group (P <0.05). In the PCT group, the postoperative 2dBUN, PCT, and PCT group (P <0.05) were all lower than those in the MPCNL group (P <0.05). No postoperative 2dBUN, PCT and PCT groups (P <0.05) (P <0.05);After surgery of the FURSL group, the 2dBUN, PCT and PCT group (P <0.05) were all lower than those of the MPCNL group (P <0.05). None of the results were statistically significant. The ureteroscopic holmium laser lithotripsy group applied natural cavity technology without surgical incision, which causes small harm to the patient, the patient recovers quickly after the operation, will not cause serious kidney damage, and the patient need not bear severe pain after surgery, and the chance of complications is relatively low. Compared with minimally invasive percutaneous nephrolithotripsy, the time will be longer for 2 to 3 cm, and the first surgical stone clearance is lower than that of minimally invasive percutaneous nephrolithotripsy. The time of treatment should also be determined by the state of the patients condition.

Conclusion: Jiyitong capsule is both targeted and scientific, and has significant effect on the excretion of renal stones in patients, which can effectively shorten the treatment cycle of patients and improve the overall quality of life
文摘Objective: to analyze and study the nursing methods and nursing effects of patients with upper urinary tract stones after treatment with ureteroscopic holmium laser lithotripsy. Methods: the study began in January 2020 and ended in November 2021. Forty-eight patients who came to the hospital for treatment during the study period were selected as the research objects. All of them were hospitalized for upper urinary tract stones. They were divided into two different groups by random drawing of lots. They were named as the contrast group and the observation group, with 24 patients in each group. Holmium laser lithotripsy with flexible ureteroscope was used as the treatment between the two groups. The former received surgical treatment while carrying out routine care, while the latter carried out comprehensive care. The nursing effect between the groups was compared and analyzed. Results: compared with the two groups, the operation index of the observation group was better (p < 0.05). The clinical indexes of the observation group improved more (P < 0.05). The observation group had a relatively lower incidence of complications and higher nursing satisfaction (P < 0.05). In terms of quality of life, the observation group improved better (P < 0.05). Conclusion: in the process of implementing ureteroscopic holmium laser lithotripsy for patients with upper urinary tract calculi, combined with comprehensive nursing intervention can produce a relatively ideal intervention effect, which is suitable for universal use.
文摘Objective: to evaluate the therapeutic value of holmium laser lithotripsy with flexible ureteroscope in the treatment of patients with isolated renal kidney calculi. Methods: 84 patients with isolated renal kidney calculi in this study were randomly selected from 2018/1 to 2020/1 and divided into two groups. One group was the control group treated with percutaneous nephrolithotomy (n=42) and the other group was the experimental group treated with ureteroscopic holmium laser lithotripsy (n=42). The operation conditions and prognosis indexes of the two groups were evaluated. Results: through the clinical treatment using the "laser lithotripsy" technique of flexible ureteroscope holmium, aiming at the patients in the experimental group, the operation process will lead to intraoperative blood loss, and effectively control the operation time, hospital stay time and relevant index value of catheter indwelling time set by laser lithotripsy during the operation. The observation group is obviously better than the control group using percutaneous nephroscope treatment (P < 0.05), but the first-stage stone removal rate of the experimental group is not different from that of the control group (P > 0.05). Conclusion: for kidney calculi patients with "isolated kidney" before operation, laser lithotripsy with special clinical treatment of "flexible ureteroscope and holmium" is adopted during the treatment, and the treatment effect is significant in stone removal. The operation time is short, the postoperative recovery is fast, and the hospitalization time is short, which reduces the economic burden for patients and is helpful for popularization.
