Bilateral urinoma due to an unilateral impacted ureteral calculus

A unilateral impacted lower ureteric calculus presenting as bilateral urinoma is rare, and spontaneous rupture of the ureter being the cause is even rarer. It is important to distinguish this uncommon condition from the much commoner condition of urinary extravasation from forniceal rupture. We are reporting a case of left lower ureteric calculus causing spontaneous rupture at the upper ureter presenting as bilateral retroperitoneal urinoma.
