Urinoma as the result of a 3mm stone in ipsilateral ureter: A rare case report.

Leakage from the kidney, ureter, bladder, and urethra, which mainly occur due to trauma, forms urinoma. The best tool for diagnosis of urinoma is enhanced-computed tomography with delayed imaging. Apart from injury, ureteral stone can induce urinoma, however, it is rare. Herein, we report a case with urinoma, which probably formed as a result of overdistention of renal pelvis after a large amount of fluid intake (about 3 L) in a short period of time (about an hour) in the presence of a 3mm stone in ipsilateral ureter.
