title: [Idiopathic retroperitoneal fibrosis causing obstructive uropathy: a case report].
abstract: Idiopathic retroperitoneal fibrosis leading to obstructive uropathy is a rare disease in our country, so a typical case deserves presentation. The patient is a 56-year-old female to have a clinical manifestation of obstructive uropathy. Retrograde pyelogram permitted 5 Fr. ureteral catheter to pass the stenotic segment. At the mean-time, there was hydronephrosis, medial deviation and gradual thinning and pointing of the middle segment of the ureter (classic triad). Computed tomography revealed that retroperitoneal soft tissue plaque enveloped aorta, inferior vena cava, and bilateral ureters. The patient received ureterolysis with ureter intraperitonealization and lateralization. The plaque was pathologically proved fibrosis. Renal function became normal postoperatively.
