| History: 60 year-old man with extensive local recurrence of rectal cancer after low anterior resection and chemoradiation. He underwent a revision abdominal perineal resection and radical cystoprostatectomy with ileal conduit diversion. The surgery was complicated by delayed abdominal and perineal wound healing which progressed to drainage from the perineal wound. Analysis of fluid drained from the perineum revealed a high creatinine level suggesting urine leak.
For further evaluation of the renal function and ntegrity of the ileal conduit,and for possible localization of the level of the leak, a renal scan was performed.
