Renal pseudoaneurysms can also occur after renal inflammation; however, such cases are rare and seldom reported.<\/jats:p><\/jats:sec>Case presentation<\/jats:title>A 53\u2010year\u2010old man presented to our emergency room with a 3\u2010day history of fever and right back pain. A blood sample revealed severe inflammation and computed tomography showed an 8\u2009mm diameter stone in the right middle ureter and hydronephrosis. The patient was diagnosed with calculous pyelonephritis and underwent emergency ureteral stenting and antibiotic therapy. On day 8 of hospitalization, hematuria and right back pain developed, and on day 9 bladder tamponade and anemia developed. Contrast\u2010enhanced computed tomography revealed a ruptured pseudoaneurysm, and the patient underwent successful angioembolization.
