Bowel preparation versus no preparation before ileal urinary diversion.

Objectives: To compare the outcome and complications of urinary diversion using ileum, with and without bowel preparation. Recent studies have questioned the necessity of bowel preparation, especially for urinary diversion when ileum is used.

Methods: In this clinical trial, 30 candidates for urinary diversion underwent a 3-day standard bowel preparation (group 1), and 32 were admitted 24 hours before surgery and received only a soft diet, with no oral intake, 8 hours before surgery (group 2).
