Urinoma secondary to surgical spinal fusion: Radiologic diagnosis and treatment

Abstract

We have presented a case of urinoma secondary to ureteral injury during spinal fusion via retroperitoneal approach demonstrated by CT. The presumed diagnosis of urinoma was confirmed and treated by interventional radiologic techniques.

Perinephric Urinoma Due to Locally Advanced Recto-Sigmoid Tumor: Incidental Finding on Bone Scan

“…It is postulated to occur when three factors present: (1) Functioning kidney, (2) tear in the urinary tract, and (3) element of ureteral obstruction to some extent. [1]…”

“…It is postulated to occur when three factors present: (1) Functioning kidney, (2) tear in the urinary tract, and (3) element of ureteral obstruction to some extent. [1] It usually results from urine leak due to blunt or penetrating trauma, iatrogenic injury, or back pressure by downstream obstruction due to a ureteral stone, surgical ligature, or abdominal or pelvic mass. As compared with renal urine leaks, ureteral urine leaks commonly occur due to iatrogenic injury following genitourinary, retroperitoneal, pelvic, or gynecologic surgery.…”

“…As compared with renal urine leaks, ureteral urine leaks commonly occur due to iatrogenic injury following genitourinary, retroperitoneal, pelvic, or gynecologic surgery. [2] Case reports of urinomas resulting from rare conditions such as retroperitoneal fibrosis [3] or as a complication of surgical spinal fusion procedure [1] have been reported. In our case, the direct invasion of the recto-sigmoid tumor to the left ureter was the cause for the urine leak and collection.…”
