    Objectives To describe the most recent 7 year experience with 137 Indiana pouch patients at a single institution and provide data on complications with this type of urinary diversion during the first postoperative year. Methods We queried our bladder cancer database to identify all patients who underwent cystectomy with continent catheterizable urinary reservoir between 2012 and 2018. Pre-, intra-, and postoperative data were collected. Complications were stratified into early (within 90 days) and midterm (90-365 days). The primary outcomes were postoperative complications, and overall and cancer-specific mortality. Results A total of 137 patients underwent open cystectomy with Indiana pouch creation. Of these, 93% were radical cystectomies. On average, the operation took 422 minutes. There were 53 (39%) patients who experienced any type of complication during the first postoperative year (Clavien II-V). Twenty-five patients (18.2%) readmitted in the early postoperative period vs 18 (13.1%) patients midterm. There were 10 (7.3%) patients that required early reoperation and 11 (8%) in the midterm period. The overall mortality rate was 1.5% early and 3.7% midterm, with the majority of the mortality rate attributed to cancer progression (85.7%). Conclusion Patients undergoing continent catheterizable reservoir urinary diversion appear to have comparable complication rates to other urinary diversions published in the literature. At high-volume urologic institutions, Indiana Pouch creation is a suitable option for select patients desiring a continent diversion.

    Objective: To analyze the oncological outcomes of men undergoing primary RPLND and characterize the use of adjuvant chemotherapy and template dissections. Methods: Retrospective review of Indiana University testis cancer database identified patients who underwent a primary RPLND between 01/2007 and 12/2017. Patients and providers were contacted to obtain information regarding adjuvant therapy, recurrence, and survival. Primary outcome was recurrence-free survival (RFS). Kaplan-Meier curves assessed survival differences stratified by pathologic stage, template of dissection, and use of adjuvant chemotherapy. Results: Overall, 274 patients were included. Most men presented with CS-I disease (214, 78%). A modified unilateral template was performed in 257 (94%) and bilateral template in 17 (6%). Overall, 148 (54%) and 126 (46%) of men had Pathologic Stage I (PS-I) and PS-II disease, respectively. Thirteen patients (10%) with PS-II disease were treated with adjuvant chemotherapy. With a median follow-up was 55 months, only 33 (12%) patients recurred. Of the 113 patients with PS-II disease who did not receive chemotherapy, 21 (19%) relapsed and 81% were cured were surgery alone and never recurred. No difference in RFS was noted between modified and bilateral template dissections. Conclusions: The use of adjuvant chemotherapy has been minimal over the past decade. The majority (81%) of men with PS-II disease were cured with RPLND alone and were able to avoid chemotherapy. Modified unilateral template dissection provided excellent oncologic control while minimizing morbidity.
