Abstract
INTRODUCTION AND HYPOTHESIS Pelvic organ prolapse following a radical cystectomy is challenging to treat and recurrence of prolapse after primary repair is common owing to compromised pelvic floor support and tissue quality. Vaginal prolapse repairs are often preferred because of concern for patients' complex intraabdominal pathological conditions. However, for those with recurrent prolapse following colpocleisis, limited definitive treatment options exist. METHODS This surgical video presents a 64-year-old G4P4 with a history of radical cystectomy with an Indiana Pouch for invasive urothelial carcinoma who presented with recurrent stage IV vaginal prolapse two years following colpocleisis. Owing to thin vaginal tissue, a sacrocolpopexy with vaginal mesh could not be performed, thus, the patient underwent robotic-assisted vaginal hernia repair with a polypropylene-reinforced ovine tissue matrix attached to Cooper's ligament and the levator ani muscles. RESULTS The surgery was free from complications and her postoperative Pelvic Organ Prolapse Quantification examination revealed a leading vaginal tissue remnant at the level of the hymen. The patient reported overall improved health and quality of life following surgery and recovery on postoperative validated questionnaires. CONCLUSIONS Vaginal and pelvic floor hernia repair with a polypropylene-reinforced tissue matrix is a feasible definitive surgical treatment for patients with prior radical cystectomy in whom colpocleisis has failed.

Abstract
A 9 yr old male miniature poodle presented with acute diarrhea, vomiting, and a distended abdomen. A large and firm mass was palpated in the caudal abdomen. Radiography showed a large soft-tissue mass in the mid ventral abdomen. The mass was mildly contrast-enhancing and in contact with the right cranial aspect of the bladder on computed tomography. The mass was heterogeneous with minimal blood flow on Doppler examination. Surgery confirmed its origin of the urinary bladder, and it was diagnosed leiomyosarcoma on pathology. This is the first report of extraluminal leiomyosarcoma of the bladder wall with imaging characteristics using various modalities.

Abstract
PURPOSE To investigate the relationship between urine cytology results after overnight continuous saline irrigation (OCSI) following transurethral resection of bladder tumor (TURBT) and bladder tumor recurrence in non-muscle invasive bladder cancer (NMIBC). MATERIALS AND METHODS A retrospective study was conducted on patients diagnosed with NMIBC between 2016 and 2020 after undergoing TURBT at our hospital. All patients received OCSI following TURBT and had urine cytology test at postoperative 1 day. Urine cytology was classified into three groups: Negative, low-grade urothelial neoplasm (LGUN)+atypical urothelial cells (AUC), and suspicious for high-grade urothelial carcinoma (SHGUC)+high-grade urothelial carcinoma (HGUC). Recurrence-free survival (RFS) in each group was compared using the Kaplan-Meier method. Univariable and multivariable Cox regression analyses were performed to evaluate independent prognostic factors. RESULTS A total of 172 patients were included in this study. Based on urine cytology group (after OCSI), RFS did not reach the median value in the Negative group. In the LGUN+AUC group, the median RFS was 615.00 days. In the SHGUC+HGUC group, the median RFS was 377.00 days. In survival analysis, the Negative group had a longer RFS than the SHGUC+HGUC group (p=0.013). However, Cox regression analysis showed that SHGUC+HGUC was not an independent prognostic factor for recurrence. CONCLUSIONS Urine cytology results after OCSI following TURBT in NMIBC were associated with bladder tumor recurrence. Specifically, SHGUC or HGUC in urine cytology after OCSI showed earlier recurrence than negative cases. However, further research is needed to accurately determine whether it is an independent prognostic factor.

Abstract
OBJECTIVES To compare health-related quality of life (HRQOL), cost-effectiveness, and survival among different types of urinary diversion (UD) utilized after radical cystectomy (RC) for bladder cancer with consideration of the unique economic and cultural context in Iran. PATIENTS AND METHODS In this retrospective study, we examined all patients who underwent RC from May 2017 to December 2021 at two specialized centers by the same surgical team. Patients were grouped based on their UD. Post-surgical HRQOL (obtained from EORTC QLQ-C30 and QLQBLM-30), financial burden, surgical complications, and survival were compared. Kruskal-Wallis H test, One-way ANOVA, and Kaplan-Meier analyses were utilized; accordingly. RESULTS AND LIMITATIONS In total 187 patients were identified-orthotopic neobladder (ONB) (N = 75), ileal conduit (IC) (N = 57), and cutaneous ureterostomy (CU) (N = 55)-and were followed for a median 17.5 (Interquartile range: 7.0, 47.0) months. ONB was associated with better HRQOL, especially in the domains addressing physical, role and social functioning (p = 0.003, 0.011, 0.045) as well as better body image (p < 0.001), lower short- and long-term financial burden (p = 0.034 and <0.001, respectively), marginally lower complication rate (p = 0.049), and better 5-year overall survival (p < 0.001), in comparison with other UDs. Patients who underwent CU had the lowest HRQOL and worst survival. Limitations were retrospective design and possibility of selection bias. CONCLUSIONS In this first study that assesses a Middle Eastern collective; ONB seems to be the UD of choice with regard to HRQOL and economic burden when there is no contraindication.

Investig Clin Urol 2024; 65:248-255. [PMID: 38714515 PMCID: PMC11076792 DOI: 10.4111/icu.20230313] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2023] [Revised: 01/03/2024] [Accepted: 03/04/2024] [Indexed: 05/10/2024] Open
Abstract
PURPOSE This study investigated the efficacy of intravesical gemcitabine as an alternative to bacillus Calmette-Guérin (BCG) therapy. MATERIALS AND METHODS Data were retrospectively collected across seven institutions from February 1999 to May 2023. Inclusion criteria included patients with intermediate- or high-risk non-muscle invasive bladder cancer (NMIBC) who underwent transurethral resection of bladder tumors (TURBT) and received at least four sessions of intravesical gemcitabine or BCG induction therapy. Patient characteristics, complete remission (CR), occurrence, and progression rates were compared. RESULTS In total, 149 patients were included in this study (gemcitabine, 63; BCG, 86). No differences were apparent between the two groups in baseline characteristics, except for the follow-up period (gemcitabine, 9.2±5.9 months vs. BCG, 43.9±41.4 months, p<0.001). There were no consistent significant differences observed between the two groups in the 3-month (gemcitabine, 98.4% vs. BCG, 95.3%; p=0.848), 6-month (94.9% vs. 90.0%, respectively; p=0.793) and 1-year CR rates (84.2% vs. 83.3%, respectively; p=0.950). Also, there was no significant statistical difference in progression-free survival between the two groups (p=0.953). The occurrence rates of adverse events were similar between the groups (22.2% vs. 22.1%; p=0.989); however, the rate of Clavien-Dindo grade 2 or higher was significantly higher in the BCG group (1.6% vs. 16.3%, respectively; p<0.001). CONCLUSIONS Intravesical gemcitabine demonstrated efficacy comparable to BCG therapy for the first year in patients with intermediate- and high-risk NMIBC. However, long-term follow-up studies are warranted.

Abstract
AIM To investigate whether the Vesical Imaging-Reporting and Data System (VI-RADS) could be used to develop a new non-invasive preoperative grade-prediction system to partially predict high-grade bladder cancer (HG-BC). MATERIALS AND METHODS The present study enrolled 89 primary BC patients prospectively from March 2022 to June 2023. Receiver operating characteristic (ROC) curve analysis was performed to evaluate the diagnostic performance of VI-RADS for predicting HG-BC and muscle-invasive bladder cancer (MIBC) in the entire group. In the low VI-RADS (≤2) group, the decision tree-based method was used to obtain significant predictors and construct the decision-tree model (DT model). The performance of the DT model and low VI-RADS scores for predicting HG-BC was determined using ROC, calibration, and decision curve analyses. RESULTS At a cut-off of ≥3, the specificity and positive predictive value of VI-RADS for predicting HG-BC in the entire group was 100%, and the area under the ROC curve (AUC) was 0.697. Among 65 patients with low VI-RADS scores, the DT model showed an AUC of 0.884 in predicting HG-BC compared to 0.506 for low VI-RADS scores. Calibration and decision curve analyses showed that the DT model performed better than the low VI-RADS scores. CONCLUSION Most VI-RADS scores ≥3 correspond to HG-BCs. VI-RADS could be used as a grouping imaging biomarker for a pathological grade-prediction procedure, which in combination with the DT model for low VI-RADS (≤2) populations, would provide a potential preoperative non-invasive method of predicting HG-BC.

Abstract
PURPOSE To assess VIRADS performance and inter-reader agreement for detecting muscle-invasive bladder cancer (MIBC) following transurethral resection of bladder tumor (TURBT). METHODS An IRB-approved, HIPAA-compliant, retrospective study from 2016 to 2020 included patients with bladder urothelial carcinoma who underwent MRI after TURBT, and cystectomy within 3 months without post-MRI treatments. Three radiologists blinded to pathology results independently reviewed MR images and assigned a VI-RADS score. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy of VI-RADS were assessed for diagnosing MIBC using VI-RADS scores ≥ 3 and ≥ 4. Inter-reader agreement was assessed using Gwet's agreement coefficient (AC) and percent agreement. RESULTS The cohort consisted of 70 patients (mean age, 68 years ± 11 [SD]; range 39-85; 58 men) and included 32/70 (46%) with MIBC at cystectomy. ROC analysis revealed an AUC ranging from 0.67 to 0.77 and no pairwise statistical difference between readers (p-values, 0.06, 0.08, 0.97). Percent sensitivity, specificity, PPV, NPV and accuracy for diagnosing MIBC for the three readers ranged from 81.3-93.8, 36.8-55.3, 55.6-60.5, 77.3-87.5, and 62.9-67.1 respectively for VI-RADS score ≥ 3, and 78.1-81.3, 47.4-68.4, 55.6-67.6, 72.0-78.8 and 61.4-72.9 respectively for VI-RADS score ≥ 4. Gwet's AC was 0.63 [95% confidence interval (CI): 0.49,0.78] for VI-RADS score ≥ 3 with 79% agreement [95% CI 72,87] and 0.54 [95%CI 0.38,0.70] for VI-RADS score ≥ 4 with 76% agreement [95% CI 69,84]. VIRADS performance was not statistically different among 31/70 (44%) patients who received treatments prior to MRI (p ≥ 0.16). CONCLUSION VI-RADS had moderate sensitivity and accuracy but low specificity for detection of MIBC following TURBT, with moderate inter-reader agreement.

Abstract
INTRODUCTION [68 Ga]Ga-FAPI-46 PET/CT is a novel hybrid imaging method that previously showed additional diagnostic value in the assessment of distant urothelial carcinoma lesions. We hypothesized that patients with bladder cancer benefit from [68 Ga]Ga-FAPI-46 PET/CT prior to radical cystectomy for locoregional lymph node staging. MATERIALS AND METHODS Eighteen patients underwent [68 Ga]Ga-FAPI-46 PET/CT for evaluation of lymph node (LN) status in predefined LN regions. Two hundred twenty-nine intraoperatively removed LN served as histopathological reference standard. RESULTS Urothelial carcinoma (UC) spread was found in ten LN in seven different regions (14.3%). Hereby, [68 Ga]Ga-FAPI-46 PET/CT was positive in four out of seven regions (57.1%) and showed significantly increased FAPI uptake compared to non-pathological regions. In the remaining three out of seven (42.9%) regions, [68 Ga]Ga-FAPI-46 PET/CT was rated negative since no pathological increased FAPI uptake was detected or the proximity of the urinary tract prevented a differentiation from physiological uptake. CT was inconspicuous in these three regions. In total, two FAP-positive LN regions were found without histopathological counterpart. Overall, sensitivity, specificity, positive predictive value, and negative predictive value were 57.1%, 95.2%, 66.7%, and 93.0% for PET imaging. CONCLUSION In summary, this innovative [68 Ga]Ga-FAPI-46 PET/CT method showed high specificity and negative predictive value in patients with bladder UC with a future potential to optimize therapy planning.

Abstract
BACKGROUND Muscle invasive bladder cancer (MIBC) has a poor prognosis even after radical cystectomy (RC). Postoperative survival stratification based on radiomics and deep learning (DL) algorithms may be useful for treatment decision-making and follow-up management. This study was aimed to develop and validate a DL model based on preoperative computed tomography (CT) for predicting postcystectomy overall survival (OS) in patients with MIBC. METHODS MIBC patients who underwent RC were retrospectively included from four centers, and divided into the training, internal validation, and external validation sets. A DL model incorporated the convolutional block attention module (CBAM) was built for predicting OS using preoperative CT images. The authors assessed the prognostic accuracy of the DL model and compared it with classic handcrafted radiomics model and clinical model. Then, a deep learning radiomics nomogram (DLRN) was developed by combining clinicopathological factors, radiomics score (Rad-score) and deep learning score (DL-score). Model performance was assessed by C-index, KM curve, and time-dependent ROC curve. RESULTS A total of 405 patients with MIBC were included in this study. The DL-score achieved a much higher C-index than Rad-score and clinical model (0.690 vs. 0.652 vs. 0.618 in the internal validation set, and 0.658 vs. 0.601 vs. 0.610 in the external validation set). After adjusting for clinicopathologic variables, the DL-score was identified as a significantly independent risk factor for OS by the multivariate Cox regression analysis in all sets (all P <0.01). The DLRN further improved the performance, with a C-index of 0.713 (95% CI: 0.627-0.798) in the internal validation set and 0.685 (95% CI: 0.586-0.765) in external validation set, respectively. CONCLUSIONS A DL model based on preoperative CT can predict survival outcome of patients with MIBC, which may help in risk stratification and guide treatment decision-making and follow-up management.

Abstract
OBJECTIVES Our previous study suggested that the operative procedure is critical for the development of parastomal hernia. We developed a novel procedure for the creation of an ileal conduit stoma to prevent parastomal hernia. Herein we evaluate the efficacy and safety of the procedure. METHODS A total of 113 Japanese patients underwent radical cystectomy and ileal conduit diversion for bladder cancer from January 2017 through December 2021 at our institution. After excluding those with incomplete data, 103 patients consisting of 46 (44.7%) with the conventional procedure and 57 (55.3%) with the novel procedure were consecutively enrolled. The main points of the novel procedure are as follows: (1) the passage of the ileal conduit is ≤2.4 cm in diameter in principle; (2) the posterior rectus sheath and peritoneum are vertically incised 2 cm laterally from the middle of the stoma site to make an oblique passage for the ileal conduit; and (3) the anterior rectus sheath and posterior rectus sheath with peritoneum are fixed to the ileal conduit separately. RESULTS Radiography-based parastomal hernia was observed in 11 patients (10.7%) with a median follow-up of 22.0 months. The incidences of parastomal hernia were 3.5% and 19.6% in the novel and the conventional procedure groups, respectively (p = 0.011). The former had a significantly lower cumulative incidence of parastomal hernia (p = 0.008, log-rank test). No specific complications associated with the procedure were observed. CONCLUSIONS The results of the preliminary cohort study suggest that the novel procedure is safe and effective for the prevention of parastomal hernia.

Abstract
INTRODUCTION Bladder cancer is a global disease, ranks as the fourth most prevalent cancer. The incidence and prevalence increase with age. Grade and aggressiveness have been found to be related with different genetic expression and mutation. AIMS To evaluate any relation of grade and invasiveness of urothelial cancer with varied expression of immune histochemical marker p63 and her2/neu. MATERIALS AND METHODS The present study was a hospital based prospective cross-sectional study. This Study was conducted from July 2021 to April 2023 in the Urology department of a tertiary care hospital. Total 90 patients undergoing trans urethral resection of bladder tumour (TURBT) were included in this study. RESULT It was found that, patients who had decreased p63 expression had high grade in tumours (93.1%) compared to patients who were expressing normal p63 (32.8%) and this was statistically significant (p < 0.0001). Tumours with decreased p63 also appeared to be more invasive, 62.1% were found to be muscle invasive. Tumours with her2 neu expression found to be more aggressive in nature, 85.7% had high grade features and 53.6% were muscle invasive. CONCLUSION Our findings suggest that immunohistochemical expression of HER2/neu positive and decreased p63 expression were associated with high grade and invasiveness in case of bladder carcinoma.

Abstract
OBJECTIVE To compare outcomes related to survival and post-operative complications in individuals older and younger than 80 years with bladder cancer undergoing radical cystectomy (RC). METHODS We conducted a systematic search using three large databases: PubMed, EMBASE, and Scopus. We included observational studies comparing outcomes between individuals older than 80 years and younger patients undergoing RC. The outcomes of interest included overall survival, disease-specific survival, progression-free survival, and risk of post-operative complications. We applied a random effects model for the analysis and reported pooled effect sizes as odds ratios (ORs) or hazards ratios (HRs) along with 95% confidence intervals. RESULTS We analyzed 21 studies. Our results show that individuals older than 80 years had higher risks of mortality at 30 days (OR 2.82; 95% CI 1.97, 4.04), 90 days (OR 3.34; 95% CI 2.61, 4.27), 12 months (HR 3.03; 95% CI 2.64, 3.49), and 24 months (HR 3.54; 95% CI 2.27, 5.50) of the post-operative follow-up than younger individuals. In addition, individuals older than 80 years also had poor 5-year survivals (HR 2.17; 95% CI 1.64, 2.88), an increased risk of 5-year cancer-specific mortality (HR 1.58; 95% CI 1.24, 2.03), poor 5-year recurrence free survivals (HR 1.49; 95% CI 1.07, 2.08), and high complications risks (OR 1.20; 95% CI 1.02, 1.42) when compared to younger patients. CONCLUSION Individuals older than 80 years undergoing RC are likely to have poor survival-related outcomes and increased complications risks. Pre-planned comprehensive geriatric assessments (CGAs) may be needed to offer better peri- and post-operative care to improve the outcomes in this patient population.

Abstract
OBJECTIVE To compare the cost-utility of initial management of high-grade T1 non-muscle invasive bladder cancer (HGT1 NMIBC) with intravesical BCG vs immediate radical cystectomy. High-risk NMIBC patients may climb a costly ladder of treatments, culminating in radical cystectomy for oncologic or symptomatic benefit in up to one-third. This high healthcare resource utilization presents a challenging dilemma in balancing sufficiently aggressive management with cost, toxicity, and quality-of-life. METHODS Cost-utility of initially managing HGT1 with intravesical BCG and early radical cystectomy with ileal conduit urinary diversion was compared using decision-analytic Markov models. Five-year oncologic outcomes, adverse event rates, and published utility values were extracted from literature. Costs were calculated from a US Medicare perspective in 2021 US dollars. Sensitivity analysis identified drivers of cost and break-even points for recurrence and progression. RESULTS Mean costs were $26,093 for intravesical BCG and $39,720 for immediate radical cystectomy, though cystectomy generated a gain of 2.2 quality-adjusted life years (QALYs) compared to intravesical BCG. Immediate cystectomy was a more cost-effective management strategy for HGT1 NMIBC with an incremental CE ratios (ICER) of $7120/QALY. The costs associated with cystectomy, TURBT, and BCG toxicity had the greatest impact on ICER. One-way sensitivity analysis demonstrated that intravesical BCG became a cost-effective management strategy if the 5-year recurrence rate of HG T1 was less than 56% or the 5-year progression rate to MIBC was less than 4%. CONCLUSION At current prices, treatment of high-grade T1 NMIBC with early radical cystectomy is more cost-effective management strategy than initial treatment with intravesical BCG.

Abstract
OBJECTIVE To evaluate a cohort of patients diagnosed with benign ureteroenteric stricture (UES) after radical cystectomy with ileal conduits using a strict predefined definition of strictures. Additionally, we want to illustrate the UES debut, regarding symptoms and clinical findings. UES is a well-known long-term complication after radical cystectomy, affecting up to 20% of all patients. In the literature, different incidence rates are reported. However, these are based on various definitions of strictures. METHODS We used strict predefined criteria to evaluate UES incidence including symptoms, timing, diagnostic methods, treatment, and outcome in all patients who underwent radical cystectomy with an ileal conduit between 2012 and 2018 at a single high-volume center. RESULTS Of a total of 693 patients who underwent radical cystectomy with ileal conduit, we found 109 patients with 135 UES in total, corresponding to 15.7% of patients (CI: 13.2-18.6) and 10% of all included ureteroenteric anastomosis (CI: 8.5-11.6) after radical cystectomy. Median follow-up was 24months (interquartile range (IQR): 12-31), and postoperatively UES was diagnosed after a median of 6months (IQR: 3-16). A total of 56% was diagnosed with elevated creatinine. Every UES underwent a median of two (IQR: 1-2) treatment attempts and 122 UES were treated successfully. CONCLUSION Benign UES is a significant cause of morbidity following radical cystectomy. Our findings contribute to the knowledge of timing, incidence, and recommended treatment of strictures. We argue the importance of establishing a clear gold standard when defining UES to ensure accurate reporting in future research.

"I think my vagina is still there?": Women's perspectives on sexual function and dysfunction following radical cystectomy for bladder cancer, a qualitative study. J Sex Med 2024; 21:464-470. [PMID: 38491395 DOI: 10.1093/jsxmed/qdae025] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2023] [Revised: 01/22/2024] [Accepted: 01/28/2024] [Indexed: 03/18/2024]
Abstract
BACKGROUND Women's sexual health after radical cystectomy is an important but poorly understood aspect of bladder cancer survivorship. Dedicated investigation is needed to elucidate patient perceptions on sexual function and dysfunction in this setting. AIMS In this study we sought to qualitatively examine women's perceptions and experiences of sexual health following radical cystectomy for bladder cancer. METHODS We conducted one-on-one qualitative telephone interviews with 40 women who underwent radical cystectomy in the past 6 months to 5 years and signed a research consent form to be contacted for future studies. We examined women's experiences of engaging in sexual activity after surgery and their attitudes toward sex and body image. We audio recorded, transcribed, and coded the interviews using ATLAS.ti software and applied grounded theory methods for analysis. OUTCOMES For data that emerged during the qualitative interviews that was related to lack of knowledge about how physical and psychological sexual health would be affected after surgery, we reviewed and discussed transcripts that enabled coding of the data into emerging topic areas. RESULTS Our analysis yielded 4 main themes. (1) Women reported receiving little to no information from providers about female sexual dysfunction prior to or after radical cystectomy. Women wished they had been provided more information about female sexual dysfunction from their clinicians, including strategies for postoperative self-pleasure and nonintercourse methods of sexual pleasure with partners. (2) Women shared that they were not sexually active following surgery due to physical and mental barriers. (3) When women did try to engage in sex, they described feeling disappointed that it did not feel the same as prior to surgery. (4) Some women found that physical therapy helped them to physically and mentally recover their strength to engage in sexual activity again. CLINICAL IMPLICATIONS Clinicians must directly address sexual health concerns with patients who undergo radical cystectomy. STRENGTHS AND LIMITATIONS This study has several key strengths. Investigation into women's sexual function and dysfunction addresses a gap in understanding of this component of women's health-related quality of life after radical cystectomy, which represents an unmet need. The large number of interviews conducted as well as the in-depth information obtained through one-on-one interviews are additional strengths. This study also has limitations, including possible shortcomings of telephone interviews compared with in-person interviews. However, telephone interviews were beneficial because the interviews took place during the COVID-19 pandemic and spared patients from extra visits or from having to travel long distances to the respective medical centers. Other possible limitations were that patients may have been reluctant to share all of their experiences and that patients who underwent urostomies, also termed ileal conduits, were overrepresented in this study compared with women who underwent continent urine diversions, which allow greater control over urine output. CONCLUSION Broadening the understanding of sexual health beyond sexual intercourse to encompass sexuality and self-pleasure can provide clinicians, patients, and their families with more effective preparation and strategies to care for an essential aspect of their wellbeing.

Abstract
OBJECTIVE Radical cystectomy (RC) for bladder cancer is associated with an inherent risk of complications and even postoperative mortality. The number of hospitals performing RC has decreased in Sweden over time, and since a formal regional centralization in 2017 cystectomy care is currently provided by nine hospitals. MATERIAL AND METHODS In the Swedish National Urinary Bladder Cancer Register (SNRUBC) 90-day complications after RC have been registered with high coverage since 2012. Descriptive data and short-term outcomes were compared in relation to centralization of the cystectomy care by stratifying data before (2012-2016) and after (2017-2023). RESULTS Out of all 4,638 cystectomies, 2,738 (59%) were performed after the centralization in 2017 and onwards. The median age at RC increased from 71 (Inter Quartile Range [IQR] 65-76) to 73 (IQR 67-77) years, and the proportion of patients with comorbidity (American Society of Anesthesiologists [ASA] 3 or 4) increased from 32% to 37% after the centralization (p < 0.001). The number of patients suffering from high-grade complications within 90 days of surgery corresponding to Clavien grade three were 345 (18%) and 407 (15%), and corresponding to Clavien grade four 61 (3%) and 64 (2%) before and after centralization, respectively. Reoperations within 90 days of RC decreased from 234/1,900 (12%) to 208/2,738 (8%) (p < 0.001), and 90-day mortality decreased from 84/1,900 (4%) to 85/2,738 (3%) (p = 0.023) before and after centralization, respectively. CONCLUSION After the centralization of the cystectomy-care in Sweden, older patients and individuals with more extensive comorbidity were offered RC whereas 90-day mortality and the proportion of patients subjected to reoperations within 90 days of surgery decreased without increasing waiting times.

Abstract
PURPOSE No studies relied on a standardized methodology to collect postoperative complications after robot-assisted radical cystectomy (RARC). The aim of our study was to evaluate peri- and post-operative outcomes of patients undergoing RARC adhering to the European Association of Urology (EAU) recommendations for reporting surgical outcomes and using a long postoperative follow-up. MATERIALS AND METHODS 246 patients who underwent RARC with intracorporal urinary diversion at a single tertiary referral center with a postoperative follow-up ≥ 1 year for survivors. Postoperative outcomes were collected prospectively by interviews done by medical doctors. Complications were scored using the Clavien-Dindo classification (CD), grouped by type and severity (severe: CD score ≥ 3). We described peri- and post-operative outcomes and complication chronological distribution. RESULTS Overall, 16 (6.5%) and 225 patients (91%) experienced intraoperative and postoperative complications, respectively. Moreover, 139 (57%) experienced severe complications. The most common any-grade and severe complications were infectious (72%) and genitourinary (35%), respectively. Overall, 52% of complications (358/682) occurred within 10 days from surgery, and 51% of severe complications (106/207) occurred within 35 days. However, 13% of complications (90/682) and 28% of severe complications (59/207) occurred 3 months after surgery. The earliest complications were fever of unknown origins and paralytic ileus (median time-to-complication [mTTC]: 4 days), the latest complications were urinary tract infection (mTTC: 40 days) and hydronephrosis/ureteral obstruction (mTTC: 70 days). CONCLUSIONS The rate of postoperative complications after RARC is > 90% when a standardized collection method and a long follow-up is implemented. These results should be used to identify potential areas of improvement and for preoperative patient counseling.

Abstract
OBJECTIVES The aim of the study is to assess the efficacy of the established computed tomography (CT)-based radiomics nomogram combined with radiomics and clinical features for predicting muscle invasion status in bladder cancer (BCa). METHODS A retrospective analysis was conducted using data from patients who underwent CT urography at our institution between May 2018 and April 2023 with urothelial carcinoma of the bladder confirmed by postoperative histology. There were 196 patients enrolled in all, and each was randomized at random to either the training cohort (n = 137) or the test cohort (n = 59). Eight hundred fifty-one radiomics features in all were retrieved. For feature selection, the significance test and least absolute shrinkage and selection operator (LASSO) approaches were utilized. Subsequently, the radiomics score (Radscore) was obtained by applying linear weighting based on the selected features. The clinical and radiomics model, as well as radiomics-clinical nomogram were all established using logistic regression. Three models were evaluated using analysis of the receiver operating characteristic curve. An area under the curve (AUC) and 95% confidence intervals (CI) as well as specificity, sensitivity, accuracy, negative predictive value, and positive predictive value were included in the analysis. Radiomics-clinical nomogram's performance was assessed based on discrimination, calibration, and clinical utility. RESULTS After obtaining 851 radiomics features, 12 features were ultimately selected. Histopathological grading and tortuous blood vessels were included in the clinical model. The Radscore and clinical histopathology grading were among the final predictors in the unique nomogram. The three models had an AUC of 0.811 (95% CI, 0.742-0.880), 0.845 (95% CI, 0.781-0.908), and 0.896 (95% CI, 0.846-0.947) in the training cohort and in the test cohort they were 0.808 (95% CI, 0.703-0.913), 0.847 (95% CI, 0.739-0.954), and 0.887 (95% CI, 0.803-0.971). According to the DeLong test, the radiomics-clinical nomogram's AUC in the training cohort substantially differed from that of the clinical model (AUC: 0.896 versus 0.845, p = 0.015) and the radiomics model (AUC: 0.896 versus 0.811, p = 0.002). The Delong test in the test cohort revealed no significant difference among the three models. CONCLUSIONS CT-based radiomics-clinical nomogram can be a useful tool for quantitatively predicting the status of muscle invasion in BCa.
