Stomal complications of ileal conduits are significantly higher when formed in women with intractable urinary incontinence.

摘要

PURPOSE:: The ileal conduit is held to be the safest and simplest form of urinary diversion. There are few reports about long-term problems after ileal conduit formation, especially intractable urinary incontinence in females. We reviewed long-term stomal complications in patients with an ileal conduit. MATERIALS AND METHODS:: Notes on 93 consecutive patients in whom an ileal conduit was created were reviewed. Information was collected on patient demographics, indications for an ileal conduit and long-term complications, in particular parastomal and incisional hernias, stomal retraction, stenosis or prolapse and the development of a redundant loop. Mean followup available was 63.4 months (range 1 to 434). RESULTS:: A total of 33 males with a mean age of 60.1 years (range 2 to 78) and 60 females with a mean age of 48.2 years (range 4 to 79) underwent ileal conduit diversion. The main indications for an ileal conduit were intractable incontinence in 44 patients (47%), cancer in 31 (33%) and interstitial cystitis in 8 (9%). In male, continent female and incontinent female patients A parastomal hernia developed in 3 (9%), 2 (9.5%) and 12 (31%), an incisional hernia developed in 1 (3%), 1 (4.8%) and 2 (5%), stomal retraction developed in 0, 2 (9.5%) and 12 (31%), stomal stenosis developed in 0 (0%), 1 (4.8%) and 6 (15.4%), and a redundant loop developed in 0 (0%), 2 (9.5%) and 5 (12.8%), respectively. A total of 23 patients (24.7%) required further surgery for stomal problems with 13 (57%) requiring more than 1 reoperation, of whom 9 were incontinent females. CONCLUSIONS:: An ileal conduit is associated with a stomal complication rate of 34.4% (61% in incontinent females and 18% in other patients) and a 4.3% incisional hernia rate. Reoperation is required for stomal complications in 24.7% of cases. Stomal complication rates and reoperation rates vary by sex and the indication for ileal conduit, and they are significantly higher for those performed for intractable urinary incontinence in females.
