An Analysis of the 90-Day Day Outcomes of Robot- Assisted Continent Colon Pouch Urinary Diversion

Abstract Introduction Studies of right colon pouch urinary diversion have widely varying estimates of the risk of perioperative complications, reoperation, and readmission. We sought to describe the association between specific risk factors and complication, readmission, and reoperation rates following right colon pouch urinary diversion. Materials and Methods Patients undergoing robot-assisted right colon pouch urinary diversion from July 2013 to December 2022 were analyzed. Outcome measures include high-grade (Clavien-Dindo grade ≥ 3) complications within 90 days, readmission within 90 days, and reoperation at any time during follow-up. Specific risk factors such as age, gender, Body mass index (BMI), diabetes, Charlson comorbidity index (CCI), and prior abdominal surgery were analyzed to establish an association with these outcomes. Result During the study period, 77 patients underwent the procedure and were eligible to study. The average follow-up was 88.7 (SD-14) months. 90-day high-grade complications were 24.67%, and 90-day readmission was 33.76%. The cumulative rate of any reoperation was 40.2%, and major reoperation was 24.67%. Diabetes was significantly associated with an increased risk of high-grade complications and major reoperation. Higher BMI and prior abdominal surgery were associated with an increased risk of readmission. Conclusions Overall, the rate of postoperative complications, readmissions, and reoperation was high but consistent with other studies. This study helps further characterize surgical outcomes after right colon pouch urinary diversion and highlights patients who may benefit from enhanced preoperative management.
