Radiology of urinary diversions.

ABSTRACT

Radiologic evaluation of urinary diversion has three objectives: to monitor upper tract distention, to detect new urothelial tumors and to detect metastasis. The type of imaging procedure and the frequency of imaging is dictated by the urologist preference. As many surgical procedures are available for noncontinent and continent diversion, interpretation of radiographic studies requires a detailed knowledge of the type of surgical procedure that has been performed.
