title: [A case report of urinary extravasation by renal trauma Grade III successfully managed by percutaneous drainage].
abstract: A 30-year-old man was diagnosed with renal trauma Grade a and hospitalized on February 22, 2009. There was no apparent stenosis from the renal pelvis to ureter on pyelography, but computed tomography demonstrated urinary extravasation on March 2. An indwelling drainage catheter was placed percutaneously by an ultrasound-guided approach. An incidental ureter-obstructing blood clot prolonged the indwelling period of the drainage catheter, but we succeeded in avoiding open surgery. Although ureteral stenting might be generally selected for the primary management of traumatic urinary extravasation, it should be remembered that percutaneous drainage is effective in some cases. We consider it important to select the optimal treatment based on an accurate diagnosis of each case.
