Complications of Urinary Undiversion

Abstract
Complications of urinary undiversion [in humans] may be divided into those related to patient selection and those pertaining to the operation. A detailed understanding of the anatomic and physiologic alterations in the dynamics of urine transport is an essential prerequisite for the selection of suitable candidates. Two illustrative cases emphasize the necessity for complete evaluation of the upper and lower urinary tracts and meticulous attention to intraoperative detail.
