Following a blunt trauma abdomen, a patient had renal laceration and urinoma. Even after 12 days, urinoma persisted, but the patient was stable and there was no fever. Next step in management would be:

Ans. c. J-shaped urinary stentManagement of urinoma is by endoscopic intervention, with cystoscopy, retrograde pyelography, placement of a ureteral stent, urethral catheter drainage, and intravenous antibiotics."Although most post-traumatic urinomas are asymptomatic and have a spontaneous resolution rate approaching 85%, urinomas will occasionally persist.A small amount of urinary extravasation is usually not significant as long as they do not become infected.Initially, we treat the trauma by ureteric stentingOnly for large urinoma, we drain by percutaneous drainage.
