Delayed rupture of renal pseudoaneurysm: complication of percutaneous nephrostomy.

Percutaneous nephrostomy has become an increasingly acceptable therapeutic alternative, both for high-risk patients and for patients in whom the technique offers delay on avoidance of major surgery. Lack of major morbidity or mortality, palliation of symptoms, and reduced convalescent period are major advantages [i -3]. However, the procedure is not without its risks. We report a case of traumatic renal artery pseudoaneurysm following percutaneous nephrostomy with delayed rupture into the collecting system. This case also exhibits many of the therapeutic options now available to the interventional radiologist.
