Core Tip

Core Tip: To the best of our knowledge, no studies have reported renal pseudoaneurysm as a complication of rigid ureteroscopy for ureteral stones, although renal pseudoaneurysm following flexible ureteroscopic lithotripsy has been reported. Here, renal pseudoaneurysm may have existed but was exacerbated by surgery or indirectly formed due to increased renal pelvis pressure. The etiology was not clarified because computed tomography was not routinely performed preoperatively. Perioperative cough may play a role owing to a sudden increase in abdominal pressure. Based on our literature review, this is the first case report of renal pseudoaneurysm without direct intervention in the renal pelvis.
