Abstract
INTRODUCTION: Percutaneous nephrolithotomy (PCNL) is a standard, safe, and efficient method for removing large renal calculi. Despite development of endourologic equipment, complications of the PCNL are still prevalent. Even though therapeutic modalities such as mini-micro PCNL have been developed in recent years, the complications are a serious concern yet. The most important complication is hemorrhage. The hemorrhage may be either arterial or venous. Venous hemorrhage is usually treated conservatively whereas the arterial one might require transarterial embolization (TAE). Arterial hemorrhage may cause serious problems, especially in the patients with solitary kidney. CASE PRESENTATION: In the presented patient, serious retroperitoneal hemorrhage and hypotension in the preoperative and postoperative periods resulted in acute renal failure (ARF). CONCLUSIONS: It was first report of selective TAE in a patient with ARF due to post-PCNL pseudoaneurysm in solitary kidney. Super-selective segmental embolization was performed successfully in this case and was shown to be a reliable and efficient procedure.
