title: Long-term follow-up after ileocaecal continent cutaneous urinary diversion (Mainz I pouch): A retrospective study of a monocentric experience.
abstract: OBJECTIVE
  To assess the long-term follow-up after ileocaecal continent cutaneous reservoir (ICCR) and to review the late complications.
  
  
  METHODS
  In all, 756 patients underwent an ICCR in our department, with long-term follow-up data available in 50 patients. The inclusion criterion was ICCR regardless of the indication and the exclusion criteria were orthotopic neobladder or other continent urinary diversions not performed with the ileocaecum. Patients were followed to record primary outcomes and late complications. Complications were stratified according to the Clavien-Dindo classification.
  
  
  RESULTS
  The mean patient age was 44 years and pelvic malignancies were the first indication for urinary diversion. The mean (range) follow-up was 19 (9-36) years. A stoma stenosis was the most frequent outlet-related complication requiring re-intervention, followed by ischaemic outlet degeneration, and stoma incontinence. Six renal units (RUs) developed obstruction at the anastomotic site and were managed by open surgery. Three RUs had to be removed due to deterioration. A dederivation was necessary in three patients (6%).
  
  
  CONCLUSIONS
  The ICCR is a safe and established technique when an orthotopic pouch is impossible. The long-term follow-up shows acceptable complication rates and satisfactory continence conditions. However, large population studies are necessary to confirm this observation.
