Introduction: Sacral neuromodulation (SNM) is a treatment approved for use in several conditions including refractory overactive bladder (OAB) and voiding dysfunction. Chronic pelvic pain (CPP) is a debilitating condition for which treatment is often challenging. SNM shows promising effect in patients with refractory CPP. However, there is a lack of clear evidence, especially in long‐term outcomes. This systematic review will assess outcomes of SNM for treating CPP.Methods: A systematic search of MEDLINE, Embase, Cochrane Central and clinical trial databases was completed from database inception until January 14, 2022. Studies using original data investigating SNM in an adult population with CPP which recorded pre and posttreatment pain scores were selected. Primary outcome was numerical change in pain score. Secondary outcomes were quality of life assessment and change in medication use and all‐time complications of SNM. Risk of bias was assessed using the Newcastle Ottawa Tool for cohort studies.Results: Twenty‐six of 1026 identified articles were selected evaluating 853 patients with CPP. The implantation rate after test‐phase success was 64.3%. Significant improvement of pain scores was reported in 13 studies; three studies reported no significant change. WMD in pain scores on a 10‐point scale was −4.64 (95% confidence interval [CI] = −5.32 to −3.95, p < 0.00001) across 20 studies which were quantitatively synthesized: effects were maintained at long‐term follow‐up. Mean follow‐up was 42.5 months (0–59). Quality of life was measured by RAND SF‐36 and EQ‐5D questionnaires and all studies reported improvement in quality of life. One hundred and eighty‐nine complications were reported in 1555 patients (Clavien‐Dindo Grade I‐IIIb). Risk of bias ranged from low to high risk. Studies were case series and bias stemmed from selection bias and loss to follow‐up.Conclusion: Sacral Neuromodulation is a reasonably effective treatment of Chronic Pelvic Pain and significantly reduces pain and increases patients’ quality of life with immediate to long‐term effects.

Introduction: Adjuvant therapy has no defined role for patients with positive surgical margins (PSMs) following radical cystectomy (RC) for muscle-invasive bladder cancer (MIBC). The aim of our study was to describe loco-regional recurrence-free survival (LRFS), metastatic-free survival (MFS), recurrence-free survival (RFS), cancer-specific survival (CSS) and overall survival (OS) and identify predictors of each endpoint in patients with PSMs following RC for MIBC. Methods: A collaborative retrospective cohort study was conducted on 394 patients with PSMs who underwent RC for MIBC between January 2000 and December 2018 at 10 tertiary referral centers. Patients receiving perioperative radiotherapy were excluded from the study. Kaplan–Meier curves were used to estimate patient survival. Cox regression analysis was used to identify predictors of survival. Results: Median age at surgery was 70 years (IQR 62–76) with 129 (33%) and 204 (52%) patients had pT3 and pT4 tumors, respectively. Nodal metastasis (pN+) was identified in 148 (38%). Soft tissue PSMs were found in 283 (72%) patients, urethral PSMs in 65 (16.5%), and ureteral PSMs were found in 73 (18.5%). The median follow-up time was 44 months (95% CI 32–60). Median LRFS, MRFS, RFS, CSS, and OS were 14 (95% CI 11–17), 12 (95% CI 10–16), 10 (95% CI 8–12), 23 (95% CI 18–33), and 16 months (95% CI 12–19), respectively. On multivariable Cox regression analysis, the pT3–4 stage, pN+ stage, and multifocal PSMs were independent predictors of LRFS, MRFS, RFS, and OS. Adjuvant chemotherapy improved all oncological outcomes studied (p < 0.05). The number of lymph nodes removed was independently associated with better LRFS, MRFS, and RFS. Advanced age at diagnosis was independently associated with worse OS. Conclusion: Patients with PSMs following RC have poor outcomes since half of them will recur within a year and will die of their disease. Among all PSMs types, patients with multifocal PSMs harbor the worst prognosis. We observed a benefit of adjuvant chemotherapy, but clinical trials evaluating innovative adjuvant strategies for these patients remain an unmet need.

Objective: To determine the oncological impact of extended pelvic lymph node dissection (ePLND) vs standard PLND (sPLND) during radical cystectomy (RC) in clinically lymph node‐positive (cN+) bladder cancer (BCa). Patients and Methods: In this retrospective, multicentre study we included 969 patients who underwent RC with sPLND (internal/external iliac and obturator lymph nodes) or ePLND (sPLND plus common iliac and presacral nodes) with or without platin‐based peri‐operative chemotherapy for cTany N1‐3 M0 BCa between 1991 and 2022. We assessed the impact of ePLND on recurrence‐free survival (RFS) and the distribution of recurrences (locoregional and distant recurrences). The secondary endpoint was overall survival (OS). We performed propensity‐score matching using covariates associated with the extent of PLND in univariable logistic regression analysis. The association of the extent of PLND with RFS and OS was investigated using Cox regression models. Results: Of 969 cN+ patients, 510 were 1:1 matched on propensity scores. The median (interquartile range [IQR]) time to recurrence was 8 (4–16) months, and median (IQR) follow‐up of alive patients was 30 (13–51) months. Disease recurrence was observed in 104 patients in the ePLND and 107 in the sPLND group. Of these, 136 (27%), 47 (9.2%) and 19 patients (3.7%) experienced distant, locoregional, or both distant and locoregional disease recurrence, respectively. When stratified by the extent of PLND, we did not find a difference in recurrence patterns ( P > 0.05). ePLND improved neither RFS (hazard ratio [HR] 0.91, 95% confidence interval [CI] 0.70–1.19; P = 0.5) nor OS (HR 0.78, 95% CI 0.60–1.01; P = 0.06) compared to sPLND. Stratification by induction chemotherapy did not change outcomes. Conclusion: Performing an ePLND at the time of RC in cN+ patients improved neither RFS nor OS compared to sPLND, regardless of induction chemotherapy status. Pretreatment risk stratification is paramount to identify ideal candidates for RC with ePLND as part of a multimodal treatment approach.
