Abstract:
A 35-year-old female patient presented with swelling pain at left waist for 1 month. Left renal pelvis stones were found and standard percutaneous nephrolithotomy was successfully performed. Two weeks later, the patient suddenly suffered massive bleeding presented with gross hematuria. Rupture of ectopic renal artery pseudoaneurysm was identified by computed tomography and angiography of the renal artery. Emergency selective angioembolization of one branch of the artery was performed. To our knowledge, this is the first report of ruptured ectopic renal arterial pseudoaneurysm.
