We reported five cases of urinary extravasation and discussed the role of diagnosis and treatment.
Three cases of them had unknown causes, two were cured within several days and the other for about two weeks. The rest cases were ureter stone and postoperative ureteral stricture of uterine cancer. The former had persistent slight fever and flank pain, therefore, ureterolithotomy was performed. The latter had paralytic ileus caused by extavasated urine and the operation was performed.
Excluding insufficient cases, we studied 104 cases of urinary extravasation which were reported in Japan from 1968 to 1984 including these cases. It was greatly difficult to perform an accurate diagnosis which was spontaneous rupture of the ureter, that of the renal pelvis or spontaneous peripelvic extravasation. Therefore, on the exprience of our percutaneous renal surgery, we proposed new clinical diagnostic criterias for them and reviewed 104 cases agin and discussed the diagnosis and teatment of theme.
