[Spontaneous peripelvic extravasation after the operation of rectal cancer, treated by indwelling the ureteral stent: report of three cases].
Three cases of spontaneous peripelvic extravasation after the operation of rectal cancer are reported. In case 1, a 65-year-old female complained of left flank pain one month after high-anterior resection for rectal cancer. Drip infusion pyelography (DIP) and retrograde pyelography (RP) showed extravasation from the left renal pelvis. The ureteral stent was indwelled, and the extravasation showed remission. In case 2, a 55-year-old female complained of left lumbago 6 months after Miles' operation for rectal cancer. DIP showed extravasation from the left renal pelvis. The same findings were confirmed on the repeated DIP after 10 days. The ureteral stent was indwelled, and the extravasation was cured. In case 3, a 69-year-old male complained of left flank pain and left abdominal tumor 10 months after Miles' operation for rectal cancer. DIP and RP showed extravasation from the right renal pelvis, and computed tomographic (CT) scan showed urinoma formation. Drainage of the urinoma was performed and the ureteral stent was indwelled. The urinoma and the extravasation was cured. We emphasized the usefulness of indwelling the ureteral stent for the conservative management of spontaneous peripelvic extravasation caused by a malignant tumor, and a discussion of the relevant literature follows.
