Novel Creation of a Noneverted Stoma During Ileal Conduit Urinary Diversion: Technique and Short-term Outcomes


      To report our experience with a noneverted stoma technique used in ileal conduit urinary diversion. We successfully utilize this technique in patients when traditional everted stoma maturation is difficult due to a thick abdominal wall, bulky mesentery, and poor bowel compliance.


      We retrospectively reviewed all patients who underwent surgical creation of ileal conduit using a noneverted stoma technique between 2009 and 2018. We recorded demographic and perioperative information, including 30-day postoperative complications, and stoma appearance at last follow-up visit. Using R software, chi-square testing of the distribution of stoma outcomes for obese and nonobese patients was performed.


      There were a total of 42 patients who underwent noneverted stoma maturation technique by a single surgeon. Our cohort meets obese criteria with a mean body mass index (BMI) of 30.2. Mean length of follow-up was 16.6 months (1-62). On follow-up, 35 (83.3%) of stomas were pink and everted appearing, 4 (9.5%) were flush, small, or noneverted, 1 (2.3%) had an eschar or area of granulation tissue around the stoma, and 2 (4.7%) did not have a stoma description documented. There were 9 (21%) stoma-related complications in our cohort. There was no statistical difference in stoma outcomes between obese (BMI > 30) and nonobese (BMI < 30) patients (P= .65).


      Ileal conduit creation with a noneverted stoma provides good stoma protuberance in patients with a thick abdominal wall, bulky mesentery, and poor bowel compliance. This technique is safe and should be considered in patients in whom stoma maturation is difficult.
