Outcomes of right colon continent urinary pouch using standardized reporting methods.

Aims: Studies of right colon pouch urinary diversion estimate risk of perioperative complications, 1%-50%, and reoperation, 1%-69%. This wide range is due to variable outcome measurements and reporting methods; it is also unclear which factors increase the risk of complications and reoperation. We sought to characterize the impact of patient-specific factors on risk of complications, readmission, and reoperation after right colon pouch urinary diversion.

Methods: Patients undergoing right colon pouch urinary diversion from January 2010 to April 2017 were analyzed. Outcomes included: high-grade complications within 90 days (Clavien-Dindo grade ≥3), readmission within 90 days, and reoperation at any time during follow-up. Patient-specific factors were analyzed to establish any associations with these outcomes.

Results: During the study period, 53 patients underwent the procedure and the average follow-up was 30 (standard deviation [SD] 21.5) months; 90-day high-grade complications were 22% and readmission was 45%. The cumulative rate of any reoperation was 53% and major reoperation was 32%. Diabetes was associated with an increased risk of both postoperative complications and reoperation. Larger body mass index and prior abdominal surgery were associated with increased risk of readmission.

Conclusions: Overall the rate of postoperative complications, readmissions, and reoperation was high, but in agreement with other contemporary series. This study helps to further characterize surgical outcomes after right colon pouch urinary diversion, however, similar to other studies in the literature, the rarity of the procedure limits the power to establish a link between preoperative patient factors and outcomes.
