Androgen deprivation therapy does not increase rates for reintervention, complication, or infection in primary penile implant or artificial urinary sphincter surgery: a retrospective cohort study from the TriNetX network.

Prostate cancer treatment-related erectile dysfunction and stress urinary incontinence are commonly treated with inflatable penile prosthesis (IPP) or artificial urinary sphincter (AUS). Given the association with androgens and penile/urethral health, we aim to evaluate whether patients on androgen deprivation therapy (ADT) undergoing IPP or AUS surgery are at increased risk for reintervention, complication, or infection. We queried the TriNetX database for adult males receiving IPP or AUS. The ADT cohort included those on ADT 3 months before or any time after surgery. We performed sub-analysis for leuprolide and bicalutamide. Cohorts and outcomes were defined by Current Procedural Terminology and International Classification of Diseases codes. Propensity score matching was performed using age, prostate cancer, history of prostatectomy, and history of radiation. Outcomes were reintervention (revision, removal, or replacement), infection, and complication. Analytics were performed in March 2024. 13,432 patients received an IPP and 5676 received an AUS, 465 and 745 of whom were on ADT, respectively. The only significant AUS analysis was for patients on abiraterone having fewer reinterventions (10.5% vs 20.8%, RR = 0.50 [0.29, 0.88]). Patients receiving an IPP with ADT had fewer reinterventions (7.2% vs 12%, RR = 0.60 [0.39, 0.92]) and complications (12.7% vs 18.5%, RR = 0.68 [0.49, 0.95]). Those on a GnRH agonist had fewer reinterventions (7.4% vs 11.7%, RR = 0.63 [0.41, 0.98]) for IPP. Patients receiving an IPP on bicalutamide had fewer reinterventions ( <5.2%* vs 10.8%, RR = 0.48 [0.23, 0.99]) and on leuprolide had fewer complications (12.2% vs 19.3%, RR = 0.63 [0.43, 0.91]). The remainder of analyses showed no significant differences. Patients with IPP or AUS do not fare worse on ADT. Further evaluation into the duration of ADT may provide clinical context, but based on these results, ADT should not limit implant surgery.

Bowel complications and anastomotic leak after ileocolic anastomosis in urinary diversion surgery: a comparative 12-year retrospective single-center study.

There is limited data within the urologic literature regarding bowel complications and leak rates following surgery requiring ileocolic anastomoses such as right colon pouch (RCP) and continent cutaneous ileocecocystoplasty (CCIC). We aimed to establish ileocolic anastomotic leak rates in urologic reconstructive surgery and determine bowel-related complications following RCP and CCIC surgeries. We reviewed adult patients who underwent RCP or CCIC (2010-2022), investigating patient characteristics, perioperative variables, and outcomes. We used Cox Proportional Hazards analysis to compare bowel-related complications. Patients with proximal ileostomy were excluded from analysis, as well as those with less than 90 days follow-up. Of 162 patients, 106 (65.4%) underwent RCP and 56 (34.6%) underwent CCIC. The mean age was 55.5 (13.1) and 40.3 (14.6) years in RCP and CCIC group (P<0.001). The leading etiology was radiation injury [34 (32.1%)] and spinal cord injury [32 (57.1%)] for RCP vs. CCIC. In the RCP group, there were 46 (43.4%) patients readmitted within 90 days and 12 (20.7%) in the CCIC group, (P=0.01). Survival, at a median follow-up of 30 (10.3-66.6) months, was 82.1% and 87.5% in the RCP vs. CCIC group (P=0.37). Anastomotic leak occurred in 8 (7.5%) patients in the RCP and 2 (3.6%) patients in the CCIC group (P=0.32). Notably, we found that the type of anastomosis, stapled reinforced lines compared to single-layered (hand sewn or stapled), significantly influenced both bowel complications [hazard ratio (HR): 0.1; 95% confidence interval (CI): 0.03-0.33] and anastomotic leaks (HR: 0.17; 95% CI: 0.04-0.75). There were no significant differences in bowel complications (HR: 0.6, 95% CI: 0.15-2.4) or anastomotic leaks (HR: 0.38, 95% CI: 0.06-2.21) between RCP and CCIC groups. This study establishes ileocolic anastomotic leak rates in a large urologic patient population. Our findings highlight the protective role of double-layered ileocolic anastomosis reinforced with hand-sewn sutures in reducing bowel complications and anastomotic leaks. There were no significant distinctions between RCP and CCIC in survival rates and bowel complications.

Efficacy and Complications of Mitrofanoff Continent Urinary Diversion in Adults with Complex Urethral Strictures: A Single-Center Experience.

The management of complicated and irreparable urethral strictures can be challenging, and continent urinary diversion has emerged as a viable option. This study aims to investigate the complications associated with continent urinary diversion using the Mitrofanoff principle in patients with complex urethral strictures that cannot be corrected through urethroplasty surgery. A total of 22 patients were included in this study, who underwent continent urinary diversion surgery using the Mitrofanoff technique. The patients were monitored for post-surgical complications over an average follow-up period of 28.36±14.26 months. Surgical failure was defined as the inability to completely and regularly empty urine from the new urinary tract. Half of the patients experienced surgical complications, with only one case resulting in surgery failure. The most common complication observed was stoma stenosis. Two patients reported slight urinary leakage from the stoma site. Notably, all patients except one, regained control over their urine after the procedure. Early therapeutic interventions were classified according to the Clavien-Dindo grading system, showed that none of the patients experienced severe complications (grade 4 or 5). The study examines the outcomes of continent urinary diversion using the Mitrofanoff technique in adults with complex urethral strictures, providing realistic expectations of complications. Overall, the study shows that this approach is a viable option with a high success rate and manageable complication for individuals with complex urethral strictures that cannot be corrected through urethroplasty surgery.

Variation in Urology Care After Urinary Stone Surgery Among Veterans at High-risk for Recurrence

ObjectiveTo determine rates of urology follow-up and implementation of stone prevention measures after stone surgery and to assess variation in care delivery within a large, integrated healthcare system. Materials and MethodsWe used nationwide data from the United States Veterans Health Administration to identify patients who had stone surgery between 2016 and 2018 and who were at higher risk for recurrence. Our cohort included 13,444 Veterans across 90 facilities. We examined the proportion of patients who had a post-operative urology visit or who received a prevention measure (24-hour urine test, serum parathyroid hormone measurement, or prescription of a stone-related medication) within 6 months of stone surgery. We calculated the median odds ratio to quantify facility-level variation in urology care after stone surgery, adjusting for patient- and facility-level characteristics. ResultsWithin 6 months of stone surgery, 94.2% Veterans had a urology visit, yet only 8.8% completed 24-hour urine testing, 8.4% had a parathyroid hormone measurement, and 31.0% were prescribed a stone-related medication. Implementation of prevention measures varied widely across facilities with the median odds ratio ranging between 1.18 for medication prescriptions and 1.77 for 24-hour urine testing. ConclusionsWhile most patients have a urology visit after stone surgery, stone prevention measures were implemented infrequently and inconsistently for patients at higher risk for recurrence, indicating an opportunity for quality improvement.

Skin preparation before artificial urinary sphincter surgery: is there a difference between protocols?

Artificial urinary sphincter (AUS) is the gold standard for severe male stress urinary incontinence (SUI). This study aims to evaluate the interest of a new cutaneous preparation regarding the risk of early device infection. A retrospective review of medical records has been built with all patients who underwent an AUS, implanted by experienced surgeons, between January 2010 and January 2023. Before January 2015, all AUS received a standard protocol (SP) of cutaneous cleansing with soap povidone iodine and disinfection with alcoholic povidone iodine. After January 2015, all AUS received the new protocol (NP) with two cleansings with soap povidone iodine and two disinfections with alcoholic povidone iodine. The primary focus was to compare the risk of early device infection between the two protocols. Multivariate analyses were done with several risk factors such as age, diabetes, underlying pathology (prostate cancer surgery, surgical treatment of benign prostatic hyperplasia or others), past history of pelvic radiation therapy and past AUS implantation. One hundred and fifty-six cases were enrolled, with 34 following the SP and 122 following the NP. In the univariate analysis, there were 15 explantations in the SP arm versus 8 for the NP arm due to infection (45.5% vs. 25%, P=0.09). The was no difference between the NP and the SP in multiparametric analysis [odds ratio (OR): 0.97; P=0.96]. No other risk factors were associated with increased risk of AUS removal. Our study showed no correlation between the two types of skin preparation and the risk of AUS removal or revision. Future studies are needed to highlight the legitimate risk factors.

Carbon-Ion Radiation therapy for Adenocarcinoma of the Uterine Cervix: Clinical Outcomes of a Multicenter Prospective Registry-Based Study in Japan (2016-2020)

Cases of adenocarcinoma of the uterine cervix (AUC) have poorer prognoses than those of squamous cell carcinoma. Carbon-ion radiation therapy (CIRT) outcomes for AUC have been reported in retrospective or single-institutional prospective studies but not prospective multicenter studies. We present the results of CIRT for AUC in a prospective multicenter study using a nationwide hospital-based registry in Japan. Patients with locally advanced untreated AUC who received CIRT at 4 Japanese centers between June 2016 and April 2020 were included in this study. In the absence of organ dysfunction, up to 5 weekly 40 mg/m2 cisplatin courses were administered. The primary endpoints were 2-year overall survival and local control rates. The secondary endpoints were 2-year disease-free survival rate and late adverse events (AEs). Forty-two patients were enrolled with a median age of 54 years (range, 34-76 years). Patients were diagnosed with stage IIB (n = 26), IIIB (n = 12), or IVA (n = 4) disease. The median follow-up period was 24 months. The 2-year overall survival, local control, and disease-free survival rates were 97.5% (95% CI, 92.7%-100.0%), 80.9% (95% CI, 66.9%-94.8%), and 64.3% (48.1%-80.4%), respectively. Two patients developed grade 3 rectum/sigmoid AE. One patient required urinary diversion surgery during a salvage operation for local tumor recurrence (grade 3 genitourinary AE). No other grade 3 or worse toxicities were reported. CIRT is an effective treatment for locally advanced AUC. Further research is required to validate the safety and efficacy of CIRT for AUC.

Surgical strategies in artificial urinary sphincter revision surgery: troubleshooting the complications.

Post-prostatectomy urinary incontinence (PPUI) is an important issue in the urological practice and imposes a negative effect on quality of life (QoL). Despite recent technological advances, PPUI remains a common complication and the artificial urinary sphincter (AUS) is regarded as the most effective long-term surgical treatment for moderate-to-severe stress urinary incontinence. Success rates for AUS as defined by a continence status of zero to one pad per day range from 59% to 90%. One potential downside of the AUS is the need for periodic revisions in a number of patients. Revision and explantation rates due to mechanical failure, urethral atrophy, infection and erosion vary considerably among studies with reports of 8-45% and 7-17%, respectively. These complications can be classified into different categories, including recurrent or refractory incontinence, erosion and/or infection, and other complications. This review article aims to describe the main AUS-related complications and their management strategies. Diagnostic work-up strategies are explored to facilitate timely identification and management of these complications. Additionally, emerging technologies and future directions in AUS development are discussed, highlighting potential advancements to mitigate complications and enhance device performance. This review consolidates current knowledge and provides insights for clinicians to manage the complexities associated with AUS therapy effectively.

Lessons learned from the Sexual Medicine Society of North America fellowship bootcamp.

Sexual Medicine Society of North America (SMSNA) fellowships offer variable experience in sexual health domains: erectile dysfunction, Peyronie's disease, male infertility, male hypogonadism (low testosterone), reconstruction (including male incontinence), benign prostatic hyperplasia, gender affirmation surgery, sexual mental health, and female sexual dysfunction. To evaluate baseline and postbootcamp understanding and trust in these domains. In 2023, 28 of 31 urologists currently enrolled in SMSNA-endorsed fellowships participated in a 3.5-day training bootcamp in Minneapolis, Minnesota. Participants were asked to complete pre- and postbootcamp surveys. The bootcamp curriculum offered American Urological Association guidelines and case-based lectures, hands-on clinical training with cadavers (penile surgery) and models (collagenase training), and interaction with industry. Changes in knowledge, independence, and trust in performing the procedures, as well as billing issues and feedback for future bootcamps. Prebootcamp surveys revealed vastly varied residency experience. Reported time with an expert faculty member was greatest for benign prostatic hyperplasia and least for female sexual dysfunction, gender affirmation surgery, and low testosterone. The lowest prebootcamp confidence in performing surgery independently was for penile grafting procedures and elevating the neurovascular bundle. Postbootcamp results revealed several areas of significant improvement in confidence (P ≤ .03): intralesional injections for Peyronie's disease, manual modeling, penile plication, penile grafting procedures, and elevating the neurovascular bundle. There was a trend for improved confidence with the insertion of inflatable (P = .05) and semirigid (P = .08) penile prostheses. Nonsignificant improvement occurred in artificial urinary sphincter surgery (P = .12). Participants graded the bootcamp very highly and requested that next year's bootcamp have more content on female sexual dysfunction, male incontinence, and low testosterone, as well as more hands-on skills sessions and case-based lecture formats. Offering a bootcamp with hands-on instruction could significantly improve urologists' knowledge and confidence. As the main strength, this study was the first specialized bootcamp for urologists in the subject of men's health, taking into account hands-on and cadaver laboratories, as well as highlighting industrial and pharmaceutical products. The small sample size was the major limitation. Current SMSNA fellows present with varied levels of experience and confidence across sexual health domains. Notable confidence improvements were seen with topics that combined didactic lectures with hands-on trainings.

The value of 3D printing model combined PCNL in kidney stones: a systematic review and meta-analysis.

With the continuous advancement of medical imaging, 3D printing technology is emerging. This technology allows for the representation of complex objects in a model form. This research aims to delve into the irreplaceable value of percutaneous nephrolithotomy (PCNL) in conjunction with 3D printed models in urinary stone surgery. This forward-looking approach provides doctors with a new perspective, enabling them to plan and execute surgeries with greater precision, ultimately delivering a safer and more efficient treatment experience for patients. We evaluated the literature on PCNL for the kidney stones with the introduction of 3D printing models and conducted a meta-analysis. The assessed parameters included stone clearance rate, operation time, hospital stay, blood loss, puncture accuracy, and the rate of complications. We systematically searched the EMBASE, PubMed, Cochrane Library, SCIE, and Chinese Biomedical Literature Search databases for articles related to PCNL (Percutaneous Nephrolithotomy) with 3D printing models from January 2000 to January 2023. Data were managed and screened using Excel . Meta-analysis was performed for operation time, stone clearance rate, blood loss, puncture accuracy, length of hospital stay, and complications in PCNL combined with 3D printing model for kidney stone treatment. The quality of included articles was assessed using the risk of bias tool by the Cochrane Collaboration. Sensitivity analysis was conducted to assess the reliability of the results. Data were recorded using StataSE 17 software, and publication bias was examined using Egger's linear regression test. We followed the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines to conduct a systematic search and screening of literature relevant to the use of 3D printed models in the treatment of kidney stones. We conducted an extensive literature search across several major academic databases, including EMBASE, PubMed, Cochrane Library, SCIE, and Chinese Biomedical Literature Search databases, to ensure comprehensive coverage of relevant studies. Following the PRISMA process of screening and analysis, we ultimately included 10 randomized controlled trials with a combined sample of 608 for systematic review. Across these studies, we identified the introduction of 3D printing models prior to surgery for kidney stones resulted in significant advantages for the experimental group compared to the control group in terms of operation time, stone clearance rates, puncture accuracy, hospital stay, blood loss, and the incidence of complications, providing valuable insights for further research and clinical practice.

Open Renal Transplantation in Obese Patients: A Correlation Study between BMI and Early and Late Complications with Implementation of a Prognostic Risk Score.

Obesity is a global epidemic that affects millions worldwide and can be a deterrent to surgical procedures in the population waiting for kidney transplantation. However, the literature on the topic is controversial. This study evaluates the impact of body mass index (BMI) on complications after renal transplantation, and identifies factors associated with major complications to develop a prognostic risk score. A correlation analysis between BMI and early and late complications was first performed, followed by a univariate and multivariate logistic regression analysis. The 302 included patients were divided into obese (BMI ≥ 30 kg/m2) and non-obese (BMI ≤ 30 kg/m2) groups. Correlation analysis showed that delayed graft function (DGF) was the only obesity-associated complication (p = 0.044). Logistic regression analysis identified female sex, age ≥ 57 years, BMI ≥ 25 and ≥30 kg/m2, previous abdominal and/or urinary system surgery, and Charlson morbidity Score ≥ 3 as risk factors for significant complications. Based on the analyzed data, we developed a nomogram and a prognostic risk score. The model's area (AUC) was 0.6457 (95% IC: 0.57; 0.72). The percentage of cases correctly identified by this model retrospectively applied to the entire cohort was 73.61%. A high BMI seems to be associated with an increased risk of DGF, but it does not appear to be a risk factor for other complications. Using an easy-to-use model, identification, and stratification of individualized risk factors could help to identify the need for interventions and, thus, improve patient eligibility and transplant outcomes. This could also contribute to maintaining an approach with high ethical standards.

Development and validation of a predictive model for double-J stent encrustation after upper urinary tract calculi surgery

The study is aimed to establish a predictive model of double-J stent encrustation after upper urinary tract calculi surgery. We collected the clinical data of 561 patients with indwelling double-J tubes admitted to a hospital in Shandong Province from January 2019 to December 2020 as the modeling group and 241 cases of indwelling double-J tubes from January 2021 to January 2022 as the verification group. Univariate and binary logistic regression analyses were used to explore risk factors, the risk prediction equation was established, and the receiver operating characteristic (ROC) curve analysis model was used for prediction. In this study, 104 of the 561 patients developed double-J stent encrustation, with an incidence rate of 18.5%. We finally screened out BMI (body mass index) > 23.9 (OR = 1.648), preoperative urine routine white blood cell quantification (OR = 1.149), double-J tube insertion time (OR = 1.566), postoperative water consumption did not reach 2000 ml/d (OR = 8.514), a total of four factors build a risk prediction model. From the ROC curve analysis, the area under the curve (AUC) was 0.844, and the maximum Oden index was 0.579. At this time, the sensitivity was 0.735 and the specificity was 0.844. The research established in this study has a high predictive value for the occurrence of double-J stent encrustation in the double-J tube after upper urinary tract stone surgery, which provides a basis for the prevention and treatment of double-J stent encrustation.

The relationship between stone-free and patient position in retrograde intrarenal surgery: a randomized prospective study

PurposeResidual fragments not removed with urinary stone surgery may become symptomatic. In this context, this study was carried out to investigate the effect of performing retrograde intrarenal surgery, which is conventionally performed in the lithotomy position, in the modified lithotomy position (Trend-side) on stone-free rates following the surgery.MethodsThis prospective study consisted of 100 patients with a single kidney stone smaller than 2 cm between 2021 and 2023. These patients were randomized into two groups of 50 patients each to be operated on in the conventional lithotomy and Trend-side positions. Variables were compared using independent t test for continuous variables and chi-square test for categorical variables.ResultsThere was no significant difference between the lithotomy and Trend-side position groups in terms of preoperative size, density, location of the stone, and hydronephrosis degree. Stone-free rate was 72% (n = 36) in the lithotomy group and 92% (n = 46) in the Trend-side group. Hence, there was a significant difference between the groups in the stone-free rate in favor of the Trend-side group (p = 0.009). Fragmentation time was statistically significantly shorter in the Trend-side group than in the lithotomy group (34 ± 17 min vs. 43 ± 14 min; p = 0.006). There was no significant difference between the groups in postoperative complication rates.ConclusionPerforming retrograde intrarenal surgery in the Trend-side position shortened the duration of fragmentation compared to the lithotomy position and was associated with higher stone-free rates. In conclusion, the Trend-side position can be safely preferred in patients undergoing retrograde intrarenal surgery due to kidney stones.

Artificial Intelligence-Powered Training Database for Clinical Thinking: App Development Study.

With the development of artificial intelligence (AI), medicine has entered the era of intelligent medicine, and various aspects, such as medical education and talent cultivation, are also being redefined. The cultivation of clinical thinking abilities poses a formidable challenge even for seasoned clinical educators, as offline training modalities often fall short in bridging the divide between current practice and the desired ideal. Consequently, there arises an imperative need for the expeditious development of a web-based database, tailored to empower physicians in their quest to learn and hone their clinical reasoning skills. This study aimed to introduce an app named "XueYiKu," which includes consultations, physical examinations, auxiliary examinations, and diagnosis, incorporating AI and actual complete hospital medical records to build an online-learning platform using human-computer interaction. The "XueYiKu" app was designed as a contactless, self-service, trial-and-error system application based on actual complete hospital medical records and natural language processing technology to comprehensively assess the "clinical competence" of residents at different stages. Case extraction was performed at a hospital's case data center, and the best-matching cases were differentiated through natural language processing, word segmentation, synonym conversion, and sorting. More than 400 teaching cases covering 65 kinds of diseases were released for students to learn, and the subjects covered internal medicine, surgery, gynecology and obstetrics, and pediatrics. The difficulty of learning cases was divided into four levels in ascending order. Moreover, the learning and teaching effects were evaluated using 6 dimensions covering systematicness, agility, logic, knowledge expansion, multidimensional evaluation indicators, and preciseness. From the app's first launch on the Android platform in May 2019 to the last version updated in May 2023, the total number of teacher and student users was 6209 and 1180, respectively. The top 3 subjects most frequently learned were respirology (n=606, 24.1%), general surgery (n=506, 20.1%), and urinary surgery (n=390, 15.5%). For diseases, pneumonia was the most frequently learned, followed by cholecystolithiasis (n=216, 14.1%), benign prostate hyperplasia (n=196, 12.8%), and bladder tumor (n=193, 12.6%). Among 479 students, roughly a third (n=168, 35.1%) scored in the 60 to 80 range, and half of them scored over 80 points (n=238, 49.7%). The app enabled medical students' learning to become more active and self-motivated, with a variety of formats, and provided real-time feedback through assessments on the platform. The learning effect was satisfactory overall and provided important precedence for establishing scientific models and methods for assessing clinical thinking skills in the future. The integration of AI and medical education will undoubtedly assist in the restructuring of education processes; promote the evolution of the education ecosystem; and provide new convenient ways for independent learning, interactive communication, and educational resource sharing.

Perioperative analgesic management in patients with bladder exstrophy: A clinical study

Background: Bladder exstrophy is a complex, rare congenital malformation with an incidence of 3.3 cases in every 100000 live births and is slightly more common in males. Primary surgical repair requires many hours of surgery with fluid and blood loss. Because of wide fluctuations in hemodynamics, a longer duration of surgery, smaller age, risk of hypothermia and post-operative intensive care may be required. We evaluated the use of continuous caudal epidural infusion of bupivacaine and fentanyl under general anesthesia for urinary bladder exstrophy-epispadias surgery in children. Aims and Objectives: Aim of the study was to evaluate the postoperative analgesia in patients undergoing surgery for bladder exstrophy. The primary objective was to assess the postoperative pain using FLACC scale and sedation score after successful caudal administration. Secondary objective was to assess the hemodynamic changes after caudal administration. Materials and Methods: A total of 13 patients aged between 9months and 13 years of either sex, weighing between 5kg to 30kg, belonging to ASA grade II to IV, underwent surgery for epispadias–exstrophy complex. Initial bolus 0.75ml/kg of 0.25% bupivacaine with fentanyl 1ug/kg was given through epidural. Postoperative analgesia was maintained by continuous infusion of 0.0625% bupivacaine @0.1ml/kg/hr in young children and 0.125% bupivacaine with fentanyl 1ug/ml in older children for 4-5 days with the help of ON-Q pump or infusion pump. Baseline hemodynamic parameters including MAP, heart rate and SpO2 was recorded at various time intervals. Postoperative pain was assessed using face, legs, activity, cry and consolability (FLACC) pain scale and sedation score was assessed by using ramsay sedation score. Results: There was a statistically significant decrease in mean pulse rate in the study group from baseline to thirty minutes after reversal (p&lt;0.001). Similar observation was made for mean arterial pressure which also showed statistically significant decrease from baseline to thirty minutes after reversal (p&lt;0.001). No change was observed in SpO2 from baseline to any other follow-up interval. Conclusion: Perioperative anesthetic and analgesic management of the bladder exstrophy patient can improve the success rate. Epidural bupivacaine with or without fentanyl infusions for short duration can provide safe analgesia.

Clinical practice guideline on bladder cancer (Part III)

AbstractBladder cancer (BC) has become a significantly prevalent disease in China, with an incidence rate of 5.80 per 100 000 in 2015, ranking it as the thirteenth most common type of cancer within the nation. This illness presents a serious public health concern, highlighting the imperative need to unify the standards for diagnosis and treatment to improve patient outcomes. The section of the clinical practice guideline in question is dedicated to addressing muscle‐invasive bladder cancer (MIBC) and metastatic BC. The primary treatment strategies for MIBC are well‐defined: preoperative (neoadjuvant) chemotherapy combined with radical cystectomy stands as the conventional treatment protocol. For patients with locally advanced MIBC, integrating systemic and local therapies is advocated to enhance treatment effectiveness. In cases of metastatic BC, the focus shifts to systemic treatment supplemented by supportive care measures. The guideline also succinctly presents the pros and cons of various urinary diversion surgeries, which are critical considerations following radical cystectomy. It provides an in‐depth exploration of the treatment modalities for metastatic urothelial carcinoma of the bladder. Additionally, this part delves into the integrated approach to treatment and the use of radiotherapy in bladder preservation for localized disease. Moreover, it offers a concise overview of the classification, diagnosis, and therapeutic approaches for nonurothelial carcinoma of the bladder. Lastly, this part emphasizes the importance of recommended posttreatment follow‐up for MIBC patients to ensure comprehensive and ongoing care management.

(177) Androgen Deprivation Therapy Does Not Increase Rates for Reintervention, Complication, or Infection in Penile Implant or Artificial Urinary Sphincter Surgery

Abstract Introduction Prostate cancer treatment carries significant quality of life implications, namely erectile dysfunction and stress urinary incontinence. Treatment options include genitourinary implants such as inflatable penile prosthesis (IPP) or artificial urinary sphincter (AUS). Given the association with androgens and penile and urethral health, there may be concern patients on androgen deprivation therapy (ADT) could have worse outcomes following IPP and AUS. Objective To evaluate whether patients on ADT undergoing IPP and AUS surgery are at increased risk for reintervention, complication, and infection. Methods We queried TriNetX, a collaborative research enterprise, for all adult male patients undergoing AUS or IPP. Cohorts were defined by those taking ADT 3 months before or anytime after surgery and those not taking ADT. ADT medications included: leuprolide, bicalutamide, flutamide, nilutamide, apalutamde, and darolide. We performed sub-analysis for leuprolide and bicalutamide, the two most prescribed ADT medications. Cohorts and outcomes were defined using Current Procedural Terminology (CPT) and International Classification of Diseases (ICD-10) codes. We used the impact of age, prostate cancer, history of prostatectomy and history of radiation to generate propensity score matching (PSM). Our primary outcome was need for reintervention (revision, removal, or replacement surgery based on CPT codes). Secondary outcomes included infection rate and complication rate based on ICD-10 codes. Analytics were performed via TriNetX on demographic data which calculated Risk Ratios and were run July 2023. Results There were 12,143 patients who received an IPP and 5487 who received an AUS (Table 1), with. 401 and 635 patients on ADT, respectively. Patients on ADT had similar rates of reintervention (9.4% vs 12.9%, RR = 0.72, p = 0.11), complication (17.7% vs 22.8%, RR =0.78, p=0.08), and infection (4.1% vs 4.8%, RR =0.84, p=0.60) for IPP. For bicalutamide, patients had lower complication rates (11.3% vs 18.2%, RR = 0.62, p=0.04) and similar reintervention rates (5.2% vs 9.9%, RR = 0.52, p=0.07). There were less than 10 instances of infection and thus TriNetX rounded these numbers to 10 (denoted by *) as part of a patient safety mechanism. Rates were similar for patients on leuprolide (reintervention: 9.8% vs 8.9%, RR =1.1, p = 0.69, complication: 17.5% vs 17.8%, RR = 0.98, p=0.92, infection: 4.0% vs 4.9%, RR = 0.81, p=0.57). Patients receiving an AUS showed similar rates for reintervention (20.8% vs 24.0% RR =0.87, p=0.17), complications (26.1% vs 25.6%, RR=1.0, p=0.85), and infections (2.3% vs 3.7%, RR=0.61, p=0.13) regardless of ADT. This held true for subanalyses for bicalutamide (reintervention: 22.7% vs 22.3%, RR =1.0, p = 0.92, complication: 27.7% vs 24.6%, RR = 1.1, p=0.43, infection: 3.8%* vs 3.8%*, RR = 1, p=1)., and leuprolide (reintervention: 19.8% vs 23.3%, RR =0.85, p = 0.18, complication: 25.3% vs 28.7%, RR = 0.8, p=0.21, infection: 1.9%* vs 3.2%, RR = 0.59, p=0.17). Conclusions Patients with IPP or AUS seemingly do no worse on ADT and in some comparisons even seemed to fare better. Further evaluation into the duration of ADT may provide clinical context, but based on these results, ADT should not limit implant surgery.

The interpretation of the updated American Urological Association guideline of interstitial cystitis/bladder pain syndrome in 2022

In 2022, American Urological Association updated the guideline for the diagnosis and treatment of interstitial cystitis/bladder pain syndrome (IC/BPS). A significant change has been made in treatment recommendations. The updated guideline no longer divided treatments into first-line through sixth-line tiers. Instead, treatment is categorized into behavioral/non-pharmacologic, oral medicines, bladder instillations, procedures, and major surgery. This change emphasizes the heterogeneity of IC/BPS patients and the importance of individualized treatment, overturns traditional unreasonable ideas about hierarchical and progressive treatment, and encourages patients and physicians to make treatment decisions together. At the same time, the panel emphasized the importance of early implementation of cystoscopy in patients suspected of Hunner lesions and warned against the possibility of pentosan polysulfate causing a unique retinal pigmentary maculopathy. Urinary reconstruction surgery was considered to only be used as a last resort for the treatment of IC/BPS, and there is uncertainty about the overall balance between benefits and risks/burdens. The updated guideline provides a new understanding and decision-making basis for the diagnosis and treatment of IC/BPS. However, it should be noted that the clinical characteristics of Chinese patients should be considered in practice and the application of the guideline should be localized.

Traumatic ureteral injury: an initial outcome and experience.

Traumatic ureteral injury is a rare and challenging condition of the urinary system. To summarize the clinical features of patients with traumatic ureteral injury and examine the literature on traumatic ureteral injuries from the past 20 years. The clinical data of 30 patients with traumatic ureteral injury in Peking University First Hospital, Beijing Jiangong Hospital, as well as Emergency General Hospital from August 2015 to August 2023 were retrospectively collected. The clinical characteristics, management strategies, and follow-up outcomes were analyzed, and a review of the literature on traumatic ureteral injury from the past 20 years was conducted. The traumatic types in the case series was composed of sharp injury, impact injury, and falling injury, with 9, 16, and 5 cases, respectively. Ureteral injury was diagnosed immediately in 12 cases, while 18 cases had a delayed diagnosis. Besides, the median time from ureteral injury to operations was 8.5 months (IQR: 4-13 months) in the patients who received upper urinary tract repair surgery, including ureteral stenting in one case, ureteroureterostomy in four cases, pyeloplasty in two cases, lingual mucosal graft ureteroplasty in one case, ileal ureter replacement in five cases, and nephrectomy in one cases. The mean follow-up time is 39.1 ± 24.8 months. Concerning renal function, postoperative creatinine was substantially lower than preoperative one (78.6 ± 13.7 µmol/L vs 88.8 ± 17.0 µmol/L, p = 0.0009), and postoperative urea was significantly lower than preoperative one (4.6 ± 1.6 µmol/L vs 5.9 ± 1. 3 mmol/L, p = 0.0016). Traumatic ureteral injury is challenging to recognize due to its deep anatomical location, making timely diagnosis crucial. It is important to choose an appropriate reconstruction method based on severity, location, length to restore urinary tract continuity as early as possible.

The Whitaker test: a predictive tool for evaluating the surgical efficacy of upper urinary tract reconstruction in patients carrying a nephrostomy tube after surgery.

To explore the role of the Whitaker test in evaluating the postoperative outcome of upper urinary tract reconstruction surgery in patients carrying a nephrostomy tube after surgery. This was a prospective observational study performed in 42 patients with nephrostomy tube undergoing the Whitaker test after upper urinary tract reconstruction surgery between January 2020 and December 2021. Data on clinical information, the Whitaker test and surgical procedure were collected prospectively, and the long-term follow-up results were analysed retrospectively. The 46 ureters of 42 patients (right 16, left 22, bilateral 4) underwent six common upper urinary tract surgical reconstruction procedures and one combined procedure, including pyeloplasty, ureteroureterostomy, lingual mucosal onlay graft, appendiceal onlay flap, ureteral reimplantation, Boari flap, and ipsilateral lingual mucosal onlay graft combined ureteral reimplantation. All patients underwent the Whitaker test successfully without any discomfort after examination. The postoperative Whitaker test showed 43 kidneys without obstruction and 3 kidneys with obstruction. At a median follow-up of 18 months (range 13-31), the follow-up results showed that the overall success rate of the surgery was 100% (46/46). Concerning the concordance Whitaker test and follow-up results, the observed proportion of agreement was 93.5% (43/46). The Whitaker test can achieve similar consistency with the long-term follow-up results after upper urinary tract reconstruction surgery and can be used as a tool to evaluate the surgical efficacy of upper urinary tract reconstruction surgery, which can provide a prognostic efficacy evaluation for patients carrying a nephrostomy tube after surgery.
