RESUMEN

BACKGROUND: We compared surgeons' workload, physical discomfort, and neuromusculoskeletal disorders (NMSDs) across four surgical modalities: endoscopic, laparoscopic, open, and robot-assisted (da Vinci Surgical Systems). METHODS: An electronic survey was sent to the surgeons across an academic hospital system. The survey consisted of 47 questions including: (I) Demographics and anthropometrics; (II) The percentage of the procedural time that the surgeon spent on performing each surgical modality; (III) Physical and mental demand and physical discomfort; (IV) Neuromusculoskeletal symptoms including body part pain and NMSDs. RESULTS: Seventy-nine out of 245 surgeons completed the survey (32.2%) and 65 surgeons (82.2%) had a dominant surgical modality: 10 endoscopic, 15 laparoscopic, 26 open, and 14 robotic surgeons. Physical demand was the highest for open surgery and the lowest for endoscopic and robotic surgeries, (all p < 0.05). Open and robotic surgeries required the highest levels of mental workload followed by laparoscopic and endoscopic surgeries, respectively (all p < 0.05 except for the difference between robotic and laparoscopic that was not significant). Body part discomfort or pain (immediately after surgery) were lower in the shoulder for robotic surgeons compared to laparoscopic and open surgeons and in left fingers for robotic surgeons compared to endoscopic surgeons (all p < 0.05). The prevalence of NMSD was significantly lower in robotic surgeons (7%) compared to the other surgical modalities (between 60 and 67%) (all p < 0.05). CONCLUSIONS: The distribution of NMSDs, workload, and physical discomfort varied significantly based on preferred surgical approach. Although robotic surgeons had fewer overall complaints, improvement in ergonomics of surgery are still warranted.

RESUMEN

BACKGROUND: To evaluate the early functional and oncological outcomes of single-port robot-assisted perineal radical prostatectomy (sp-pRARP) using the da Vinci XI system and analyze its learning curve using the cumulative sum (CUSUM) method. METHODS: The clinical data of 50 patients who underwent sp-pRARP for localized prostate cancer between May 2020 and May 2022 in our center by a single surgeon were analyzed retrospectively. Demographic information, preoperative and postoperative variables, complications, early functional and oncological outcomes of patients were recorded. The CUSUM method was used to illustrate the learning curve based on operation time. RESULTS: All surgeries were completed without conversion. The median (interquartile range, IQR) operation time was 205.0 (82.5) min, whereas the median (IQR) docking time was 30.0 (15.0) min and the console time was 120.0 (80.5) min. The median (IQR) estimated blood loss (EBL) was 50.0 (137.5) mL. Positive surgical margins were detected in five patients (10.0%). The continence rate was 40.9%, 63.6%, 88.4%, and 97.7% at the 1, 3, 6, and 12 months after surgery. According to the CUSUM plot, the inflection points of the learning curve were 20 cases, splitting the case series into "early phase" and "late phase." In "late phase" cases, there was less time spent on each step of the operation and less EBL. CONCLUSIONS: Sp-pRARP using the da Vinci XI system was verified to be a feasible and reliable surgical approach. According to the CUSUM plot, 20 cases was considered the turning point for surgeons to master the novel technique.

RESUMEN

PURPOSE: Our goal was to evaluate long-term safety and durability of response to UGN-101, a mitomycin-containing reverse thermal gel, as primary chemoablative treatment for low-grade upper tract urothelial carcinoma. MATERIALS AND METHODS: In this open-label, single-arm, multicenter, phase 3 trial (NCT02793128), patients ≥18 years of age with primary or recurrent biopsy-proven low-grade upper tract urothelial carcinoma received 6 once-weekly instillations of UGN-101 via retrograde catheter to the renal pelvis and calyces. Those with complete response (defined as negative ureteroscopic evaluation, negative cytology and negative for-cause biopsy) 4-6 weeks after the last instillation were eligible for up to 11 monthly maintenance instillations and were followed for ≥12 months with quarterly evaluation of response durability. Durability of complete response was determined by ureteroscopic evaluation; duration of response was estimated by the Kaplan-Meier method. Treatment-emergent adverse events (TEAEs) were monitored. RESULTS: Of 71 patients who initiated treatment, 41 (58%) had complete response to induction therapy and consented to long-term followup; 23/41 patients (56%) remained in complete response after 12 months (95% CI 40, 72), comprising 6/12 (50%) who did not receive any maintenance instillations and 17/29 (59%) who received ≥1 maintenance instillation. Kaplan-Meier analysis of durability was estimated as 82% (95% CI 66, 91) at 12 months. Ureteric stenosis was the most frequently reported TEAE (31/71, 44%); an increasing number of instillations appeared to be associated with increased incidence of urinary TEAEs. CONCLUSIONS: Durability of response to UGN-101 with or without maintenance treatment is clinically meaningful, offering a kidney-sparing therapeutic alternative for patients with low-grade disease.

RESUMEN

BACKGROUND: Most patients with low-grade upper tract urothelial cancer are treated by radical nephroureterectomy. We aimed to assess the safety and activity of a non-surgical treatment using instillation of UGN-101, a mitomycin-containing reverse thermal gel. METHODS: In this open-label, single-arm, phase 3 trial, participants were recruited from 24 academic sites in the USA and Israel. Patients (aged ≥18 years) with primary or recurrent biopsy-proven, low-grade upper tract urothelial cancer (measuring 5-15 mm in maximum diameter) and an Eastern Cooperative Oncology Group performance status score of less than 3 (Karnofsky Performance Status score >40) were registered to receive six instillations of once-weekly UGN-101 (mitomycin 4 mg per mL; dosed according to volume of patient's renal pelvis and calyces, maximum 60 mg per instillation) via retrograde catheter to the renal pelvis and calyces. All patients had a planned primary disease evaluation 4-6 weeks after the completion of initial therapy, in which the primary outcome of complete response was assessed, defined as negative 3-month ureteroscopic evaluation, negative cytology, and negative for-cause biopsy. Activity (complete response, expected to occur in >15% of patients) and safety were assessed by the investigator in all patients who received at least one dose of UGN-101. Data presented are from the data cutoff on May 22, 2019. This study is registered with ClinicalTrials.gov, NCT02793128. FINDINGS: Between April 6, 2017, and Nov 26, 2018, 71 (96%) of 74 enrolled patients received at least one dose of UGN-101. 42 (59%, 95% CI 47-71; p<0·0001) patients had a complete response at the primary disease evaluation visit. The median follow-up for patients with a complete response was 11·0 months (IQR 5·1-12·4). The most frequently reported all-cause adverse events were ureteric stenosis in 31 (44%) of 71 patients, urinary tract infection in 23 (32%), haematuria in 22 (31%), flank pain in 21 (30%), and nausea in 17 (24%). 19 (27%) of 71 patients had study drug-related or procedure-related serious adverse events. No deaths were regarded as related to treatment. INTERPRETATION: Primary chemoablation of low-grade upper tract urothelial cancer with intracavitary UGN-101 results in clinically significant disease eradication and might offer a kidney-sparing treatment alternative for these patients. FUNDING: UroGen Pharma.

RESUMEN

Objectives: To compare racial differences and pelvis dimensions between Caucasians and African Americans (AAs) and to develop a risk calculator and scoring system to predict the risk of prolonged operative time and presence of positive surgical margins (PSM) based on these dimensions. Materials and Methods: A retrospective review of 88 consecutive patients undergoing robot-assisted laparoscopic prostatectomy with a preoperative prostate MRI conducted. Data extraction included demographic, perioperative, and postoperative oncologic outcomes. Prostate-specific antigen (PSA) was obtained within 3 months postsurgery. Wilcoxon rank sum and Fisher's exact tests were used to compare continuous and categorical data, respectively. Single and multivariable regression analysis were used to determine contribution of each factor to the composite outcomes. A risk score was created based on this analysis for predicting the composite outcome. Results: We identified 88 consecutive patients with localized prostate cancer that underwent a preoperative prostate MRI. No statistically significant differences were found with respect to age, body mass index, or any postoperative outcome. PSA was lower at diagnosis (6.49 vs 9.72, p = 0.006) and operative times were shorter in Caucasians. Rates of PSM (13 vs 14, p = 0.35), biochemical recurrence (4 vs 2, p = 0.69), and complications did not vary between the groups. Caucasians had wider/shallower pelvis dimensions. Based on these variables, we found that the log (odds of OR time >3 hours or PSM) = -5.333 + 1.158 (if AA) +0.105 × PSA +0.076 × F -0.035 × G with an area under the receiver operating characteristic curve = 0.73. Using the predefined variables, patients can be risk stratified for PSM or prolonged operative times. Conclusions: Several pelvis dimensions were found to be shorter/narrower in AAs and were associated with longer operative times. The presented risk calculator and stratification system may be used to predict prolonged operative time or having PSM.

RESUMEN

BACKGROUND: This study investigated the impact of surgical modalities on surgeon wellbeing with a focus on burnout, job satisfaction, and interventions used to address neuromusculoskeletal disorders (NMSDs). METHODS: An electronic survey was sent to surgeons across an academic integrated multihospital system. The survey consisted of 47 questions investigating different aspects of surgeons' wellbeing. RESULTS: Out of 245 thoracic and abdominopelvic surgeons, 79 surgeons (32.2 â€‹%) responded, and 65 surgeons (82 â€‹%) were able to be categorized as having a dominant surgical modality. Compared to robotic surgeons, laparoscopic (p â€‹= â€‹0.042) and open (p â€‹= â€‹0.012) surgeons reported more frequent feelings of burnout. The number of surgeons who used any treatment/intervention to minimize the operative discomfort/pain was lower for robotic surgeons than the other three modalities (all p â€‹< â€‹0.05). CONCLUSIONS: NMSDs affect different aspects of surgeons' lives and occupations. Robotic surgery was associated with decreased feelings of burnout than the other modalities.

RESUMEN

Background and Objective: Upper tract urothelial carcinoma (UTUC) is a rare disease. The gold standard treatment is radical nephroureterectomy (RNU). Endoscopic management of UTUC has emerged as an alternative therapy that aims to preserve kidney function while providing effective oncologic control. Over the years, this has become an increasingly important alternative to RNU for treating UTUC in patients with localized disease. Advancements in lasers and endoscopic technology have continued to expand the applications of endoscopic nephron-sparing treatment. This review aims to provide an overview of the available lasers and ureteroscopic technologies used in treating UTUC with a focus on their clinical applications and outcomes. Methods: A comprehensive literature review was completed using PubMed to create this narrative mini review. Publications from peer-reviewed journals written in English between 1987 to 2022 were evaluated by the authors for inclusion. Key Content and Findings: Improvements in ureteroscopic technology have led to improved visualization and tumor detection. Laser ablation using different laser energies including the holmium/yttrium-aluminum-garnet, neodymium/YAG, and thulium/YAG has demonstrated promising oncologic outcomes. However, accurate staging and risk-stratification remain limitations to the role of laser ablation for the treatment of UTUC. This review also highlights appropriate patient selection as a critical component of successful endoscopic management. Conclusions: The continued evolution of endoscopic management will rely on the development of new technologies to improve risk stratification and oncologic outcomes. Overall, this review provides insights into the available laser therapies and ureteroscopic technologies for the endoscopic management of UTUC.

RESUMEN

To analyze operating room (OR) efficiency by evaluating fixed and variable OR times for open (OPN) and robotic-assisted partial nephrectomies (RAPN). We analyzed consecutive OPN and RAPN performed by one surgeon over a 24-month period. All patients were placed in the lateral decubitus position and secured with a beanbag regardless of approach. Fixed (non-procedural) OR times were prospectively collected and defined as: in-room to anesthesia-release time (IRAT), anesthesia release to cut time (ARCT), and close to wheels-out time (CTWO). Variable OR time was procedural cut to close time (CTCT). Comparisons of fixed and variable OR time points between OPN and RAPN were performed using the Wilcoxon rank-sum test. 146 RAPN and 31 OPN were evaluated from 2019-2020. Median IRAT was similar for RAPN versus OPN [20 min (IQR: 16-25) vs. 20 min (IQR: 16-26), P = 0.57]. Median ARCT was longer for RAPN than it was for OPN [40 min (IQR: 36-46) vs. 34 min (IQR: 30-39), P < 0.001]. Median CTWO was similar for OPN (12 min, IQR: 9-14) and RAPN (11 min, IQR: 7-15) (P = 0.89). Median CTCT was longer for RAPN (202 min, IQR: 170-236) compared to OPN (164 min, IQR: 154-184) (P < 0.001). In a single surgeon, partial nephrectomy series with the same patient positioning, utilization of robotic technology was associated with longer surgeon operating time as well as less efficient fixed OR times, specifically ARCT.

RESUMEN

PURPOSE: Data regarding the treatment of ureteropelvic junction obstruction (UPJO) in horseshoe kidneys are limited. We performed a retrospective analysis of our experience with minimally invasive treatment of UPJO in patients with this anomaly. METHODS: Between March of 1996 and March 2008, 9 patients with horseshoe kidneys were treated for UPJO at our institution. Of these patients, 6 were managed with retrograde endopyelotomy, 2 with laparoscopic pyeloplasty, and one by robotic pyeloplasty. Outcomes of these procedures were retrospectively reviewed. RESULTS: A total of nine patients were available for analysis. Four of six patients who underwent endopyelotomy had available follow-up, with a mean of 56 months. The success rate for these patients was 75%. Two of three patients (67%) in the laparoscopic/robotic cohort were successfully treated with a mean follow-up of 21 months. CONCLUSIONS: UPJO in horseshoe kidneys can pose a therapeutic dilemma. The minimally invasive treatment of these patients is feasible with good success rates for both endopyelotomy and laparoscopic/robotic pyeloplasty.

RESUMEN

OBJECTIVE: To assess longitudinal prescribing patterns for patients undergoing urologic surgery in the nearly 2-year time frame before and after implementation of an evidence-based opioid prescribing guideline to accurately characterize the impact on postoperative departmental practices. PATIENTS AND METHODS: Historical prescribing data for adults who underwent 21 urologic procedures at 3 academic institutions were used to derive a 4-tiered guideline for postoperative opioid prescribing. The guideline was implemented on January 16, 2018, and prescribing patterns including quantity of opioids prescribed (in oral morphine equivalents [OMEs]) and refill rates were compared for opioid-naïve patients undergoing urologic surgery before (January 1, 2016, through January 15, 2018; N=10,649) and after (January 16, 2018, through September 30, 2019; N=9422) guideline implementation. Univariate analysis was performed using Wilcoxon rank sum and χ2 tests. Cochran-Armitage trend tests and interrupted time series analysis were used to test for significance in the change in OMEs prescribed before vs after guideline implementation. RESULTS: The median quantity of opioids decreased from 150 OMEs (interquartile range, 0-225) before guideline implementation to 0 OMEs (interquartile range, 0-90) after guideline implementation (P<.001). Median OMEs decreased significantly in each tier and each of 21 individual procedures. Overall guideline adherence was 90.7% (n=8547). Despite this decrease in OMEs prescribed, post-guideline implementation patients obtained fewer refills than the pre-guideline implementation group (614 [6.5%] vs 999 [9.4%]; P<.001). CONCLUSION: In a multi-institutional follow-up prospective study of adult urologic surgery-specific evidence-based guidelines for postoperative prescribing, we demonstrate sustained reduction in OMEs prescribed secondary to guideline implementation and adherence by our providers.

RESUMEN

BACKGROUND: We developed evidence-based guidelines for postoperative opioid prescribing after urologic surgery and assessed changes in prescribing after implementation. METHODS: Prescribing data for adults who underwent 21 urologic procedures were used to derive a four-tiered guideline for postoperative opioid prescribing. This was implemented on January 1, 2018, and prescribing patterns including quantity of opioids prescribed (oral morphine equivalents; OME) and refill rates were compared between patients undergoing surgery prior to (January-April, 2017; n equals 1732) and after (January-April, 2018; n equals1376) implementation. RESULTS: The median OME (IQR) prescribed was significantly lower for 2018 compared with 2017 [100 (0; 175) versus 150 (60; 225); p < .0001]. The median prescribed OME decreased in 14/21 procedures (67%). The refill rates did not significantly change. Guideline adherence rates after implementation, based on individual procedures, ranged from 33 to 95%. CONCLUSIONS: Fewer opioids were prescribed after implementing a prescribing guideline. Additional study is required to assess patient opioid utilization.

RESUMEN

OBJECTIVE: To describe postoperative opioid prescribing practices in a large cohort of patients undergoing urological surgery. PATIENTS AND METHODS: We identified 11,829 patients who underwent 21 urological surgical procedures at 3 associated facilities from January 1, 2015, through December 31, 2016. After converting opioids to oral morphine equivalents (OMEs), prescribing patterns were compared within and across procedures. Subgroup analysis for opioid-naive patients (those without a history of long-term opioid use) was performed. Statistical analysis was utilized to evaluate variations based on demographic and perioperative/postoperative variables. RESULTS: Of the 11,829 patients, 9229 (78.0%) were prescribed an opioid at discharge, and the median (interquartile range [IQR]) OME prescribed was 188 (150-225). The remaining 9253 patients (78.2%) were considered opioid naive. Striking variation in prescribing patterns was observed within and across surgical procedures. For instance, IQR ranges of 150 or greater were observed for open cystectomy (median, 300; IQR, 210-375], open radical nephrectomy (median, 300; IQR, 225-375), retroperitoneal node dissection (median, 300; IQR, 225-375), hand-assisted laparoscopic nephrectomy (median, 225; IQR, 150-300), and penile prosthesis (median, 225; IQR, 150-315). On multivariate analysis, younger age, cancer diagnosis, and inpatient hospitalization were associated with higher likelihood of receiving a highest-quartile OME prescription for opioid naive patients. Thirty-day refill rates varied from 1.6% to 25.9%. Interestingly, refill rates were higher in patients receiving more opioids at discharge. CONCLUSION: The United States is facing an opioid epidemic, and physicians must take action. In this study, we found considerable variation in opioid prescribing patterns within and across surgical procedures. These data provide support for the development of standardized opioid prescribing guidelines for postoperative analgesia.

RESUMEN

PURPOSE: Although there are empiric data to show that obesity is not a contraindication for laparoscopic radical nephrectomy, similar data are lacking for the use of hand-assisted laparoscopic radical nephrectomy (HALRN) in obese patients. We evaluate whether obese patients undergoing HALRN to manage a renal mass are more likely than nonobese patients to experience poor intraoperative and perioperative outcomes. PATIENTS AND METHODS: Between June 1, 1999, and May 31, 2006, 150 patients underwent HALRN for the management of a solid renal mass at our institution. We abstracted detailed demographic, clinical, and follow-up data on all patients in this cohort. As our primary analysis, we evaluated associations between body mass index (BMI) and estimated blood loss, operative time, length of stay, and complications using linear and logistic regression models. RESULTS: There was no evidence that obese patients experienced a statistically significant or clinically relevant increase in blood loss (P = 0.97), operative times (P = 0.87) or length of stay (P = 0.62) compared with persons of normal weight. In contrast, although there was no evidence of a linear trend toward complications in patients with a higher BMI (P = 0.19), obese patients were almost three times more likely to experience a complication compared with normal-weight persons (odds ratio: 2.88; 95% confidence interval: 1.01-8.16). Adjusting for relevant clinical covariates individually did not markedly alter these associations. CONCLUSIONS: Obesity is not a contraindication for HALRN to manage a renal mass; however, obese patients should be aware that they may be at increased risk for certain complications after surgery, notably ileus and incisional hernias.

RESUMEN

ABSTRACT Purpose: To evaluate the potential oncologic benefit of a visibly complete transurethral resection of a bladder tumor (TURBT) prior to neoadjuvant chemotherapy (NAC) and radical cystectomy (RC). Materials and Methods: We identified patients who received NAC and RC between 2011-2021. Records were reviewed to assess TURBT completeness. The primary outcome was pathologic downstaging (<ypT2N0), with complete pathologic response (ypT0N0) and survival as secondary endpoints. Logistic regression and Cox proportional hazards models were utilized. Results: We identified 153 patients, including 116 (76%) with a complete TURBT. Sixty-four (42%) achieved <ypT2N0 and 43 (28%) achieved ypT0N0. When comparing those with and without a complete TURBT, there was no significant difference in the proportion with <ypT2N0 (43% vs 38%, P=0.57) or ypT0N0 (28% vs 27%, P=0.87). After median follow-up of 3.6 years (IQR 1.5-5.1), 86 patients died, 37 died from bladder cancer, and 61 had recurrence. We did not observe a statistically significant association of complete TURBT with cancer-specific or recurrence-free survival (p≥0.20), although the hazard of death from any cause was significantly higher among those with incomplete TURBT even after adjusting for ECOG and pathologic T stage, HR 1.77 (95% CI 1.04-3.00, P=.034). Conclusions: A visibly complete TURBT was not associated with pathologic downstaging, cancer-specific or recurrence-free survival following NAC and RC. These data do not support the need for repeat TURBT to achieve a visibly complete resection if NAC and RC are planned.

RESUMEN

The National Cancer Institute in cooperation with the Southwest Oncology Group has begun one of the largest prostate cancer prevention studies to date, the Selenium and Vitamin E Chemoprevention Trial (SELECT). The purpose of this article is to review the evidence and discuss the individual antioxidant compounds under study. The authors comprehensively reviewed the peer-reviewed literature on the chemoprevention of prostate cancer with emphasis on the antioxidants vitamin E and selenium. The credible leads for the primary prevention of prostate cancer using selenium and vitamin E have emerged as secondary findings from randomized controlled trials with corroborative evidence from observational and in vitro studies. Selenium and vitamin E are widely available compounds that are safe if taken in moderation, with relatively few adverse effects. The evidence in support of the antioxidants in the primary prevention of prostate cancer is promising, and the next step in definitively answering the question has been addressed by the investigators of SELECT. The SELECT study will define the role of the antioxidants selenium and vitamin E in the prevention of prostate cancer; complete data from the study will be available in 12 years.

RESUMEN

BACKGROUND AND PURPOSE: Endourology has evolved rapidly for the management of both benign and malignant disease of the upper urinary tract. Limited data exist, however, on the occupational hazards posed by complex endourologic procedures. The aim of this study was to determine the prevalence and possible causes of hand problems among endourologists who routinely perform flexible ureteroscopy compared with controls. MATERIALS AND METHODS: An online computer survey targeted members of the Endourological Society and psychiatrists in academic and community settings. A total of 600 endourologists and 578 psychiatrists were contacted by e-mail. Invited physicians were queried regarding their practice settings and symptoms of hand pain, neuropathy, and/or discomfort. RESULTS: Survey responses were obtained from 122 (20.3%) endourologists and 74 (12.8%) psychiatrists. Of endourologists, 61% were in an academic setting and 70% devoted their practice to endourology. Endourologists were in practice for a mean 13 years, performing 4.5 ureteroscopic cases per week with a mean operative time of 50 minutes. Hand/wrist problems were reported by 39 (32%) endourologists compared with 14 (19%) psychiatrists (P=0.0486, relative risk [RR]=1.69). Surgeons who preferred counterintuitive ureteroscope deflection were significantly more likely to have problems (56%) compared with intuitive users (27%) (RR 2.07, P=0.0139) or those with no preference (26%) (RR 2.15, P=0.0451). Overall, most respondents (85%) with hand/wrist problems needed either medical or surgical intervention. CONCLUSIONS: Hand and wrist problems are very common among endourologists. Future studies are needed to develop more ergonomic platforms and thereby reduce the endourologist's exposure to these occupational hazards.

RESUMEN

BACKGROUND AND PURPOSE: For many years, the gold standard in upper urinary tract transitional-cell carcinoma (UT-TCC) management has been nephroureterectomy with excision of the bladder cuff. Advances in endourologic instrumentation have allowed urologists to manage this malignancy. The feasibility and success of conservative measures for UT-TCC have been widely published, but there has not been an objective cost analysis performed to date. Our goal was to examine the direct costs of renal-sparing conservative measures v nephroureterectomy and subsequent chronic kidney disease (CKD) or end-stage renal disease (ESRD). Secondary analysis includes a discussion of survival and quality-of-life issues for both treatment cohorts. PATIENTS AND METHODS: Retrospective review of a cohort of patients treated at our institution with renal-sparing ureteroscopic management of UT-TCC who were followed for a minimum of 2 years. The costs per case were based on equipment, anesthesia, surgeon fees, pathologic evaluation fees, and hospital stay. ESRD and CKD costs were estimated based on published reports. RESULTS: From 1996 to 2006, 254 patients were evaluated and treated for UT-TCC at our institution. A cohort of 57 patients was examined who had a minimum follow-up period of 2 years. Renal preservation in our series approached 81%, with cancer-specific survival of 94.7%. Assuming a worst-case scenario of a solitary kidney with recurrences at each follow-up for 5 years v nephroureterectomy and dialysis for the same period, an estimated $252,272 U.S. dollars would be saved. This savings would cover the expenses of five cadaveric renal transplantations. CONCLUSIONS: Conservative endoscopic management of UT-TCC in our experience should be the gold standard management for low-grade and superficial-stage disease. From a cost perspective, renal-sparing UT-TCC management is effective in reducing ESRD health care expenses.

RESUMEN

Dextranomer/hyaluronic acid copolymer (Zuidex) is currently under Food and Drug Administration investigation for use as a transurethral bulking agent to treat female stress urinary incontinence secondary to intrinsic sphincter deficiency. Urethral obstruction is a recognized complication of bulking agents. We describe an aspiration method to address iatrogenic voiding dysfunction resulting from this therapy.
