title: Urinary ascites due to retroperitoneal fibrosis: a case report.
abstract: Urinary ascites in adults is usually secondary to iatrogenic or traumatic injuries. A case of a 69-year-old male with abdominal pain and decreased renal function is described. Ultrasound showed bilateral hydronephrosis and ascites. Computed tomography revealed retroperitoneal fibrosis complicated by a rupture at the right ureteropelvic junction and urine extravasation in the perirenal and intraperitoneal spaces. Delayed scans showed leaking of contrast media from the anterior perirenal space to the peritoneal cavity. The urinary ascites resolved using a double-J stent.
