Assessment for and Results of Urinary Undiversion

Summary— Twenty‐five patients with surface diversions have been assessed for undiversion over the past 3 years. Fourteen of these have been reconstructed of which half are in the more difficult myelodysplastic group. In 7 patients renal deterioration or renal failure was the indication for undiversion. The critical factors for success are good urethral mechanism function and adequate ureteric function. All but one are subjectively pleased, and all but one have stable renal function and are continent. Infection, especially Pseudomonas, must be eliminated and careful follow‐up is mandatory.
