The time to radical cystectomy (TTC) was defined as the interval between the onset of symptoms and RC. The regression coefficients of the independent predictors obtained by Cox regression were used to construct the nomogram. Discrimination, validation, and clinical usefulness in the validation cohort were assessed by the area under the curve, the calibration plot, and decision curve analysis.Results: In the developing dataset, the 1-, 5-, and 10-year RFS were 83.0%, 47.2%, and 44.4%, respectively. On multivariate analysis, independent predictors were TTC (hazards ratio [HR] 1.07, 95% confidence interval [CI] 1.05-1.08, p<0.001), PBT (one unit: HR 1.40, 95% CI 1.03-1.90, p=0.03;two or more units: HR 1.72, 95% CI 1.29-2.29, p<0.001), bilateral hydronephrosis (HR 1.54, 95% CI 1.21-1.97, p<0.001), squamous cell carcinoma (HR 0.60, 95% CI 0.45-0.81, p=0.001), pT3-T4 (HR 1.77, 95% CI 1.41-2.22, p<0.001), lymph node status (HR 1.53, 95% CI 1.21-1.95, p<0.001), and lymphovascular invasion (HR 1.28, 95% CI 1.01-1.62, p=0.044). The areas under the curve in the validation dataset were 79.3%, 69.6%, and 76.2%, for 1-, 5-, and 10-year RFS, respectively. Calibration plots showed considerable correspondence between predicted and actual survival probabilities. The decision curve analysis revealed a better net benefit of the nomogram.Conclusion: A nomogram with good discrimination, validation, and clinical utility was constructed utilizing TTC and PBT in addition to standard pathological criteria.展开更多

The aim of the current study was to determine the survival rate and prognostic factors of patients who underwent radical cystectomy for bladder cancer in a Chinese medical center. We retrospectively analyzed clinicopathologic data from 271 bladder cancer patients who underwent radical cystectomy between 2000 and 2011. Univariate and multivariate analyses were conducted to identify independent prognostic predictors for this cohort. Median follow-up was 31.7 months(range, 0.2–139.1 months). Thirty-day mortality was(1.4%). The 5-year recurrence-free survival, cancer-specific survival(CSS), and overall survival rates were 61.6%, 72.9%, and 68.0%, respectively. The 5-year CSS rates of patients with T1–T4 disease were 90.7%, 85.0%, 51.0%, and 18.0%, respectively. Patients with organ-confined disease had a higher 5-year CSS rate than those with extravesical disease(81.4% vs. 34.9%, P < 0.001). For the 38 patients(14%) with lymph node involvement, the 5-year CSS rate was 27.7%—significantly lower than that of patients without lymph node metastasis(P < 0.001). The 5-year CSS rate was much higher in patients with low grade tumor than in those with high grade tumor(98.1% vs. 68.1%, P < 0.001). Multivariate Cox regression showed that patient age(hazard ratio, 2.045; P = 0.013) and T category(hazard ratio, 2.213; P < 0.001) were independent predictors for CSS. These results suggest that radical cystectomy is a safe and effective method for treating bladder cancer in Chinese patients. Old age and high T category were associated with poor prognosis in bladder cancer patients who underwent radical cystectomy.展开更多

The levels of inflammatory factors and stress hormone preoperative and postoperative 24 h, and ovarian function of the menstrual period 3rd day preoperative and postoperative 3 months of the two groups were compared.Results: There was no significant difference in the levels of TNF-α, CRP, COR, NE, E2, LH and FSH between the two groups before the operation. Postoperative 24 h, the levels of TNF-α, CRP, COR and NE in the treatment group were significantly lower than those in the control group, and the level of E2 in the treatment group was higher than that in control group, the levels of LH and FSH in the treatment group were lower than those in control group postoperative 3 months, the difference were statistically significant.Conclusion: Compared with pneumoperitoneum laparoscopic surgery, suspended laparoscopic surgery can effectively reduce the inflammatory response, reduce the level of stress hormone and improve ovarian function in patients undergoing ovarian cystectomy, which has a certain clinical value.展开更多

文摘Objectives:Uretero-enteric strictures are feared complications following cystectomy.Despite surgical advancements,particularly the rise of robot-assisted approaches,the risk factors associated with these strictures remain poorly defined.This study aimed to identify the risk factors associated with uretero-enteric anastomotic strictures after cystectomy,according to the surgical approach and type of urinary diversion(extracorporeal vs.intracorporeal).Methods:We conducted a single-center retrospective study including 340 patients who underwent cystectomy between 2016 and 2024 at Tours University Hospital.Clinical,biological,perioperative,and postoperative data were analyzed.The occurrence of a uretero-ileal anastomotic stricture was defined radiologically by a uretero-hydronephrosis≥20 mm.We constructed and analyzed a learning curve for robotic surgery with intracorporeal urinary diversion.Results:Strictures occurred in 60 patients(17.6%).On multivariable analysis,reduced preoperative glomerular filtration rate(odds ratio[OR]=1.45 per 10 mL/min decrease,95%CI[1.12-1.87],p=0.004),elevated creatinine(OR=1.30 per 10μmol/L increase,95%CI[1.05-1.61],p=0.018),prior myocardial infarction(OR=2.25,95%CI[1.10-4.62],p=0.027),and postoperative urinary tract infection(OR=3.10,95%CI[1.65-5.82],p<0.001)were independent predictors.Most strictures were left-sided.Intracorporeal robotic diversion had a higher,though non-significant,stricture rate(21.5%vs.15.2%,OR=1.52,p=0.12).Stricture rates fell markedly after 20 robotic cases per surgeon(23.8%vs.12.1%).Conclusion:Uretero-enteric strictures are multifactorial,strongly influenced by baseline renal function,cardiovascular comorbidity,and postoperative infection.Robotic intracorporeal diversion shows a learning curve effect,underlining the importance of surgical expertise and infection prevention in reducing risk.

文摘Dear Editor,Radical cystectomy(RC)remains the standard treatment for muscle-invasive bladder cancer[1].However,urinary diversion after RC can lead to a range of postoperative complications,including parastomal hernia,incontinence,urinary retention,recurrent urinary tract infections,and metabolic disorders,significantly impacting patients'quality of life[2].Partial cystectomy(PC)is a bladdersparing alternative for patients who cannot accept RC and has been utilized in managing muscle-invasive bladder cancer since the last century.However,the application of PC has always been a subject of controversy in clinical practice due to the high recurrence rate.In a matched case-control analysis conducted by Knoedler et al.[3],38%of the patients experienced intravesical tumor recurrence,and 19%of the patients ultimately underwent RC.Another study in the Memorial Sloan-Kettering Cancer Center showed that 22 of 58 patients who received PC experienced superficial or advanced recurrence[4].
文摘Objective:This study aimed to evaluate the diagnostic accuracy of MRI in the detection of nodal metastasis in urothelial bladder cancer(UBC)and to assess the long-term oncological outcomes of upfront radical cystectomy(RC)in patients with clinical lymph node-positive(cN^(+))muscle-invasive UBC.Methods:A retrospective analysis of 1053 consecutive UBC patients treated with RC between January 1,2004 and January 31,2014 was performed.Radiological,clinical,pathological data and survival outcomes of cN^(+) patients were collected.Cox regression analyses were used to assess the impact of the radiological,clinical,and pathological variables on survival.Results:A total of 233(22%)patients were diagnosed with cN^(+) UBC with a mean age of 57.3(standard deviation 8.1)years,of whom 144(62%)were found to have pathologically positive lymph nodes at final pathology.Adjuvant chemotherapy was administered to 58(25%)patients.The sensitivity,specificity,positive predictive value,and negative predictive value of MRI to detect pathological lymph node-positive disease were 51%,88%,62%,and 83%,respectively.The overall accuracy was 79% with a calculated area under the curve of 70%.The median follow-up period was 17.0(interquartile range 8.2e58.7)months.During this period,54(23%)patients developed local recurrence while 56(24%)experienced distant metastasis and the estimated 1-,3-,5-,and 10-year recurrence-free survival for cN^(+) patients were 78%,56%,51%,and 48%,respectively.On multivariate analysis,advanced pT stage(pT3e4 vs.pT2)was the only independent predictor of recurrence-free survival.Conclusion:Despite its potential in preoperative assessment of muscle-invasive UBC,MRI showed limited sensitivity for detecting node-positive disease.Notably,in patients with MRIdetected cN^(+) UBC,those who underwent upfront RC demonstrated long-term survival outcomes comparable to those treated with neoadjuvant chemotherapy followed by consolidative cystectomy in previously published studies.
文摘Introduction:Radical cystectomy with pelvic node dissection remains the standard of care for muscle-invasive bladder carcinoma(MIBC);however,there is a growing interest in bladder preservation alternatives among the elderly population.Guidelines indicate that partial cystectomy(PC)combined with pelvic node dissection(LND)can be considered as an alternative in carefully selected individuals.Using the National Cancer Database,we analyzed the overall survival(OS)between PC with and without LND among octogenarians.Methods:We identified octogenarians with localized muscle-invasive bladder carcinoma(cT2-3N0M0)and urothelial histology who underwent PC with or without LND between 2004 and 2018.Based on the number of lymph nodes removed(LNR),the LND group was further subdivided into<10 and>=10 lymph node groups.A propensity-matched Kaplan-Meier survival analysis was performed to compare OS between these groups.Results:Among 2573 patients who underwent PC,492 octogenarians met our selection criteria.208(42.2%)had LND,while 284(57.8%)had no LND.Within the LND group,53(25.5%)had<10 LNR,and 155(74.5%)had>=10 LNR.The median OS for the matched LND and non-LND groups was 36.9 and 33.4 months(p=0.96),respectively.Similarly,<10 LNR and>=10 LNR had 36.9 and 43.5 months(p=0.42),respectively.Multivariate Cox regression analysis revealed no difference in the risk of mortality.Conclusion:Among octogenarians who underwent PC,there was no significant difference in OS between those with or without LND,and between<10 or>=10 LNR groups.Therefore,the role and extent of LND after PC need further exploration in this subset of the population.
文摘Objective:Pelvic organ-sparing surgery aims to preserve vital reproductive and sexual organs,enhancing quality of life,especially in premenopausal women.Pelvic organ preservation for female patients undergoing radical cystectomy is now emphasized for sexual and hormonal function.Recent screening studies show no survival advantage despite early diagnosis of ovarian cancer,but opportunistic salpingectomy could reduce high-grade serous carcinoma risk.The aim of this review was to analyze the incidence of metachronous or delayed ovarian cancer in patients undergoing radical cystectomy for bladder cancer.Methods:PubMed,Scopus,Web of Science,ClinicalTrials.gov,and Cochrane Library were searched systematically for English-language articles up to June 2024.The selection was done first by title and abstract screening and then by full-text assessment for eligibility.This review has been registered in PROSPERO(CRD42024561902).Results:This review included two retrospective studies(2211 patients).Most patients had local or regional advanced disease,with a minority having distant disease.Only one study reported direct pelvic organ involvement from urothelial cancer,with no ovarian involvement found.Among patients who had organ-sparing surgery or pelvic exenteration,only two developed ovarian cancer post-surgery.No mean follow-up time or side effects from pelvic organ removal were reported in either study.Conclusion:When oncologically safe,ovarian-sparing surgery with salpingectomy should be considered in female bladder cancer patients undergoing radical cystectomy.Opportunistic salpingectomy should be encouraged during abdominal urological surgeries,with thorough preoperative counseling guiding decisions.Further studies are needed to define the role of preventive gynecologic surgery in urologic procedures.
文摘Radical cystectomy(RC)with pelvic lymph node dissection(PLND)is the standard treatment for localized muscle-invasive bladder cancer(MIBC)and non-muscle-invasive bladder cancer(NMIBC)with recurrence or high risk of progression.Also,the robotic approach to this type of surgery is well established in the literature.Our objective is to summarize in this manuscript the most relevant articles related to the robotic-assisted radical cystectomy for prostate cancer.We performed a literature review of articles describing the robotic approach to RC in patients with bladder cancer.Also,we described the procedure since the patient selection until the bladder removal.The reconstructive techniques were not included in this review.Twenty-five articles were used to divide our manuscript into key points such as preoperative patient selection and protocols,surgical technique,pathology report,oncological outcomes,complication rates,and quality of life after the procedure.Robotic-assisted radical cystectomy is feasible and safe with satisfactory oncological outcomes.The robotic approach is related to lower blood loss and fewer transfusion rates.However,when compared to open surgery,the use of this technology increases the operative time.
文摘Objective: To develop and internally validate a nomogram to predict recurrence-free survival (RFS) including the time to radical cystectomy (RC) and perioperative blood transfusion (PBT) as potential predictors.Methods: Patients who underwent open RC and ileal conduit between January 1996 to December 2016 were split into developing (n=948) and validating (n=237) cohorts. The time to radical cystectomy (TTC) was defined as the interval between the onset of symptoms and RC. The regression coefficients of the independent predictors obtained by Cox regression were used to construct the nomogram. Discrimination, validation, and clinical usefulness in the validation cohort were assessed by the area under the curve, the calibration plot, and decision curve analysis.Results: In the developing dataset, the 1-, 5-, and 10-year RFS were 83.0%, 47.2%, and 44.4%, respectively. On multivariate analysis, independent predictors were TTC (hazards ratio [HR] 1.07, 95% confidence interval [CI] 1.05-1.08, p<0.001), PBT (one unit: HR 1.40, 95% CI 1.03-1.90, p=0.03;two or more units: HR 1.72, 95% CI 1.29-2.29, p<0.001), bilateral hydronephrosis (HR 1.54, 95% CI 1.21-1.97, p<0.001), squamous cell carcinoma (HR 0.60, 95% CI 0.45-0.81, p=0.001), pT3-T4 (HR 1.77, 95% CI 1.41-2.22, p<0.001), lymph node status (HR 1.53, 95% CI 1.21-1.95, p<0.001), and lymphovascular invasion (HR 1.28, 95% CI 1.01-1.62, p=0.044). The areas under the curve in the validation dataset were 79.3%, 69.6%, and 76.2%, for 1-, 5-, and 10-year RFS, respectively. Calibration plots showed considerable correspondence between predicted and actual survival probabilities. The decision curve analysis revealed a better net benefit of the nomogram.Conclusion: A nomogram with good discrimination, validation, and clinical utility was constructed utilizing TTC and PBT in addition to standard pathological criteria.

文摘The aim of this review was to systematically compare the outcomes of enhanced recovery after surgery(ERAS)with standard care(SC)after radical cystectomy.We performed a systematic search of PubMed,Ovid?Web of Science,and the Cochrane Library to identify studies published until September 2017 which involved a comparison of ERAS and SC.A meta-analysis was performed to assess the outcomes of ERAS versus SC.Sixteen studies including 8 prospective and 8 retrospective trials met the eligibility criteria.A total of 2100 participants were assigned to ERAS(1258 cases)or SC(842 cases).The time to first flatus passage[WMD=-0.95 days,95%Cl(-1.50,-0.41),P=0.0006],time until return to a regular diet[WMD=-2.15 days,95%Cl(-2.86,—1.45),P<0.00001]and the length of hospital stay[WMD=-3.75 days,95%Cl(-5.13,-2.36),P<0.00001]were significantly shorter,and the incidence of postoperative complications[OR=0.60,95%Cl(0.44,0.83),P=0.002],especially postoperative paralytic ileus[OR=0.43,95%Cl(0.30,0.62),P<0.00001]and cardiovascular complications[OR=0.28,95%Cl(0.09,0.90),P=0.03]was significantly lower in the ERAS group than those in the SC group.This meta-analysis demonstrated that ERAS was associated with a shorter time to first flatus passage,return of bowel fimction,and the length of hospital stay than SC in patients undergoing radical cystectomy,as well as a lower rate of postoperative complications,especially paralytic ileus and cardiovascular complications.

文摘During radical cystectomy(RC),the neurovascular bundles are easily removed or damaged,leading to varying rates of incontinence and erectile dysfunction.The nervesparing technique was developed to preserve urinary and erectile function.The adoption of laparoscopic and robot-assisted technology has improved visualization and dexterity of pelvic surgeries,thus facilitate the nerve-sparing technique.Although nerve-sparing RC is technically similar with nerve-sparing radical prostatectomy,there are still some anatomical differences.There are mainly three different types of nerve-sparing techniques.Pelvic lymph node dissection(PLND)is another important factor to influence erectile function and urinary continence.Nerve-sparing laparoscopic radical cystectomy(LRC)and robot-assisted radical cystectomy(RARC)may be an optimal treatment choice in well-selected younger patients with lowvolume,organ-confined disease.We should attempt to do,whenever possible,a nerve-sparing cystectomy at least on oneside.However,due to the need of a well-refined surgical technique,nerve-sparing LRC and RARC is now being performed only by experienced urological surgeons.
文摘Objective:To determine the role of neutrophil-to-lymphocyte ratio(NLR)in prognosticating survival outcomes in patients with advanced/metastatic urothelial bladder cancer.Methods:We retrospectively reviewed 84 patients undergoing radical cystectomy(RC)for UCB from January 2002 to June 2012.NLR was computed(median:5 days)prior to surgery.No patients received neoadjuvant chemotherapy.NLR was analyzed as a continuous variable and a cut-off point of 2.7 was obtained,with a statistical receiver operating characteristics of 0.74.KaplaneMeier curves,multivariate Cox proportional hazard and logistics regression models were used to predict NLR association with survival outcomes.Results:The median follow-up period was 30.1 months(range:3.2e161.7)owing to high recurrence rate and subsequent mortalities,compared to the median 64.7 months in patients alive at the end of study period.NLR2.7 was associated with worse survival outcomes(5-year disease-specific survival:22%vs 58%,p Z 0.017,95%CI:1.193e6.009;5-year overall survival:23%vs 60%,p Z 0.008,95%CI:1.322e6.147).Furthermore,on multivariate analyses,higher NLR was independently associated with higher recurrence rate(p Z 0.007,HR Z6.999,95%CI:1.712e28.606),higher T staging(p Z 0.021,HR Z 3.479,95%CI:1.212e9.990)and lymph node involvement(p Z 0.009,HR Z 4.534,95%CI:1.465e14.034).

文摘Few large scale studies have reported the oncologic outcome of radical cystectomy for treating bladder cancer in China; hence, we lack long-term prognostic information. The aim of the current study was to determine the survival rate and prognostic factors of patients who underwent radical cystectomy for bladder cancer in a Chinese medical center. We retrospectively analyzed clinicopathologic data from 271 bladder cancer patients who underwent radical cystectomy between 2000 and 2011. Univariate and multivariate analyses were conducted to identify independent prognostic predictors for this cohort. Median follow-up was 31.7 months(range, 0.2–139.1 months). Thirty-day mortality was(1.4%). The 5-year recurrence-free survival, cancer-specific survival(CSS), and overall survival rates were 61.6%, 72.9%, and 68.0%, respectively. The 5-year CSS rates of patients with T1–T4 disease were 90.7%, 85.0%, 51.0%, and 18.0%, respectively. Patients with organ-confined disease had a higher 5-year CSS rate than those with extravesical disease(81.4% vs. 34.9%, P < 0.001). For the 38 patients(14%) with lymph node involvement, the 5-year CSS rate was 27.7%—significantly lower than that of patients without lymph node metastasis(P < 0.001). The 5-year CSS rate was much higher in patients with low grade tumor than in those with high grade tumor(98.1% vs. 68.1%, P < 0.001). Multivariate Cox regression showed that patient age(hazard ratio, 2.045; P = 0.013) and T category(hazard ratio, 2.213; P < 0.001) were independent predictors for CSS. These results suggest that radical cystectomy is a safe and effective method for treating bladder cancer in Chinese patients. Old age and high T category were associated with poor prognosis in bladder cancer patients who underwent radical cystectomy.
文摘Robot-assisted radical cystectomy with intracorporeal urinary diversion(RARCICUD)has only recently been explored as a viable surgical option for patients with muscle-invasive bladder cancer seeking satisfactory oncologic control while benefiting from minimally invasive surgical techniques.Inspired by earlier open and laparoscopic work,initial descriptions of RARC-ICUD were published in 2003,and have since been followed by multiple larger case series which have suggested promising outcomes for our patients.However,the rate of adoption has remained relatively slow when compared to other robotassisted procedures such as the radical prostatectomy,likely owing to longer operative times,operative complexity,costs,and uncertainty regarding oncologic efficacy.The operative technique for RARC-ICUD has evolved over the past decade and several high-volume centers have shared tips to improve efficiency and make the operation possible for a growing number of urologists.Though there are still questions regarding economic costs,effectiveness,and generalizability of outcomes reported in published data,a growing dataset has brought us ever closer to the answers.Here,we present our current operative technique for RARC-ICUD and discuss the state of the literature so that the urologist may hold an informed discussion with his or her patients.

文摘Objective:To investigate oncological outcomes in patients with bladder cancer who underwent minimally invasive radical cystectomy(MIRC)or open radical cystectomy(ORC).Methods:We identified patients with bladder cancer who underwent radical cystectomy(RC)in 13 centers of the Chinese Bladder Cancer Consortium(CBCC).Perioperative outcomes were compared between MIRC and ORC.The influence of surgical approaches on overall survival(OS)and cancer-specific survival(CSS)in the entire study group and subgroups classified according to pathologic stage or lymph node(LN)status was assessed with the log-rank test.Multivariable Cox proportional hazard models were used to evaluate the association among OS,CSS and risk factors of interest.Results:Of 2098 patients who underwent RC,1243 patients underwent MIRC(1087 laparoscopic RC and 156 robotic-assisted RC,respectively),while 855 patients underwent ORC.No significant differences were noted in positive surgical margin rate and 90-day postoperative mortality rate.MIRC was associated with less estimated blood loss,more LN yield,higher rate of neobladder diversion,longer operative time,and longer length of hospital stay.There was no significant difference in OS and CSS according to surgical approaches(pZ0.653,and 0.816,respectively).Subgroup analysis revealed that OS and CSS were not significantly different regardless of the status of extravesical involvement or LN involvement.Multivariable Cox regression analyses showed that the surgical approach was not a significant predictor of OS and CSS.Conclusions:Our study showed that MIRC was comparable to conventional ORC in terms of OS and CSS.

文摘Objective:To investigate the effects of suspension laparoscopy and pneumoperitoneum laparoscopic surgery on inflammatory response, stress hormone and ovarian function in patients with ovarian cystectomy.Methods: Retrospective analysis of the data of laparoscopic ovarian cyst denudation in our hospital from July 2015 to August 2017, and they were were divided into the control group and the treatment group according to the surgical methods they accepted. The levels of inflammatory factors and stress hormone preoperative and postoperative 24 h, and ovarian function of the menstrual period 3rd day preoperative and postoperative 3 months of the two groups were compared.Results: There was no significant difference in the levels of TNF-α, CRP, COR, NE, E2, LH and FSH between the two groups before the operation. Postoperative 24 h, the levels of TNF-α, CRP, COR and NE in the treatment group were significantly lower than those in the control group, and the level of E2 in the treatment group was higher than that in control group, the levels of LH and FSH in the treatment group were lower than those in control group postoperative 3 months, the difference were statistically significant.Conclusion: Compared with pneumoperitoneum laparoscopic surgery, suspended laparoscopic surgery can effectively reduce the inflammatory response, reduce the level of stress hormone and improve ovarian function in patients undergoing ovarian cystectomy, which has a certain clinical value.
文摘Objective We aimed to compare perioperative and oncologic outcomes for patients undergoing robotic-assisted radical cystectomy(RARC)with intracorporeal ileal conduit(IC)and neobladder(NB)urinary diversion.Methods Patients undergoing RARC with intracorporeal urinary diversion between January 2017 and January 2022 at the Icahn School of Medicine at Mount Sinai,New York,NY,USA were indexed.Baseline demographics,clinical characteristics,perioperative,and oncologic outcomes were analyzed.Survival was estimated with Kaplan-Meier plots.Results Of 261 patients(206[78.9%]male),190(72.8%)received IC while 71(27.2%)received NB diversion.Median age was greater in the IC group(71[interquartile range,IQR 65-78]years vs.64[IQR 59-67]years,p<0.001)and BMI was 26.6(IQR 23.2-30.4)kg/m^(2).IC group was more likely to have prior abdominal or pelvic radiation(15.8%vs.2.8%,p=0.014).American Association of Anesthesiologists scores were comparable between groups.The IC group had a higher proportion of patients with pathological tumor stage 2(pT2)tumors(34[17.9%]vs.10[14.1%],p=0.008)and pathological node stages pN2-N3(28[14.7%]vs.3[4.2%],p<0.001).The IC group had less median operative time(272[IQR 246-306]min vs.341[IQR 303-378]min,p<0.001)and estimated blood loss(250[150-500]mL vs.325[200-575]mL,p=0.002).Thirty-and 90-day complication rates were 44.4%and 50.2%,respectively,and comparable between groups.Clavien-Dindo grades 3-5 complications occurred in 27(10.3%)and 34(13.0%)patients within 30 and 90 days,respectively,with comparable rates between groups.Median follow-up was 324(IQR 167-552)days,and comparable between groups.Kaplan-Meier estimate for overall survival at 24 months was 89%for the IC cohort and 93%for the NB cohort(hazard ratio 1.23,95%confidence interval 1.05-2.42,p=0.02).Kaplan-Meier estimate for recurrence-free survival at 24 months was 74%for IC and 87%for NB(hazard ratio 1.81,95%confidence interval 0.82-4.04,p=0.10).Conclusion Patients undergoing intracorporeal IC urinary diversion had higher postoperative cancer stage,increased nodal involvement,similar complications outcomes,decreased overall survival,and similar recurrence-free survival compared to patients undergoing RARC with intracorporeal NB urinary diversion.
文摘Duodenal duplication cysts are rare congenital anomalies.Duodenal duplication should be considered in the differential diagnosis of patients who present with abdominal symptoms with cystic structures neighboring the duodenum.Here,we present an 8-year-old girl with a duodenal duplication cyst treated with partial cystectomy with mucosal stripping performed laparoscopically.Laparoscopic surgery can be considered as a treatment option for duodenal duplication cysts,especially in extraluminal locations.
文摘Objective: Radical cystectomy(RC)is a standard treatment for localized muscle invasive bladder cancer and high-risk or very high-risk non-muscle invasive bladder cancer not responding to adequate endovesical therapy.In women,traditionally RC is performed with hystero-adnexectomy and resection of the anterior vaginal wall,often resulting in sexual disorders.Vaginal-sparing techniques have been developed to improve functional outcomes.The present study explores the safety and the functional outcome of vaginal-sparing techniques.Methods: We retrospectively analyzed all consecutive female patients undergoing robot-assisted RC(RARC)with neobladder diversion between October 2017 and February 2022.The indications for vaginal-sparing RC were absence of tumor on bladder neck or urethra and no sign of infiltration of posterior bladder wall at the preoperative MRI.Functional results were evaluated with the aid of five questions out of the Bladder Cancer Index questionnaire.Complications were reported according to the Clavien–Dindo classification and cancer control was evaluated by recurrence-free and cancer-specific survival.Results: A total of 22 female patients underwent RARC with neobladder diversion.Neoadjuvant chemotherapy was given in 17(77%)cases.Clavien–Dindo grades III–IV complications occurred in four(18%)cases.After a mean follow-up of 29(interquartile range 16–44)months,six(27.3%)patients developed distant metastases,and one(4.5%)woman loco-regional relapse.Sexual-sparing surgery was performed in 19(86%)patients,and in the others the anterior vaginal wall was resected,but neobladder was still performed.During daytime,no patients reported total incontinence and 73%(11/15)reported total continence or only occasional leaks.Sexual results showed that seven of 15(47%)women regained sexual activity after surgery,with a quality reported as“good”or“very good”in 40%of all 19 cases.Conclusion: RARC in female with anterior vaginal wall preservation is feasible.The approach showed a good safety profile,with satisfying results on continence and sexual activity.Sexual-sparing approaches should be carried out after correct patient selection.
文摘Objective:We described the technique and outcomes of robot-assisted repair of uretero-enteric strictures(UES)following robot-assisted radical cystectomy(RARC)and urinary diversion.Methods:Retrospective review of our RARC database from November 2005 to August 2023 at Roswell Park Comprehensive Cancer center was performed.Patients who developed UES and ultimately underwent robot-assisted uretero-enteric reimplantation(RUER)were identified.KaplaneMeier method was used to compute the cumulative incidence recurrence rate of UES after RUER.A multivariable regression model was used to identify variables associated with UES recurrence.Results:A total of 123(15%)out of 808 RARC patients developed UES,of whom 52 underwent reimplantation(45 patients underwent RUER[n=55 cases]and seven patients underwent open ureteroenteric reimplantation).The median time from RARC to UES was 4.4(interquartile range 3.0e7.0)months,and the median time between UES and RUER was 5.2(interquartile range 3.2e8.9)months.The 3-year recurrence rate after RUER is about 29%.On multivariable analysis,longer hospital stay(hazard ratio 1.37,95%confidence interval 1.16e1.61,p<0.01)was associated with recurrent UES after RUER.Conclusion:RUER for UES after RARC is feasible with durable outcomes although a notable subset of patients experienced postoperative complications and UES recurrence.

文摘Objective:Radical cystectomy is a complex lengthy procedure associated with postoperative morbidity.We aimed to assess the operative time(OT)in patients undergoing radical cystectomy and its impact on 90-day postoperative complications and readmission rates.Methods:The retrospective cohort study included 296 patients undergoing radical cystectomy and urinary diversion from May 2010 to December 2018 in our institution.The OT of 369 min was set as a cutoff value between short and long OT groups.The primary outcome was 90-day postoperative complication rates.Secondary outcomes were gastrointestinal recovery time,length of hospital stay,and 90-day readmission rates.Results:The overall incidence of 90-day postoperative complications was 79.7%where 43.2%representing low-grade complications according to the ClavieneDindo classification(Grade 1 and Grade 2),and 36.5%representing high-grade complications(Grade3).Gastrointestinal tract and infectious complications are the most common complications in our data set(45.9%and 45.6%,respectively).On multivariable analysis,prolonged OT was significantly associated with odds of high-grade complications(odds ratio 2.340,95%confidence interval 1.288e4.250,p=0.005).After propensity score-matched analysis,a higher incidence of major complications was identified in the long OT group 55(51.4%)compared to 35(32.7%)in the short OT group(p=0.006).A shorter gastrointestinal tract recovery time was noticed in the short OT group(p=0.009).Prolonged OT was associated with a higher 90-day readmission rate on univariate and multivariate analyses(p<0.001,p=0.001,respectively).
