A case of bilateral ureteral fibrosis is reported. The patient, a 32-year-old man, was admitted as a result of acute renal failure. Ultrasonography showed bilateral hydronephrosis, so that in-dwelling percutaneous nephrostomy tubes were immediately inserted in the bilateral kidneys. Since retrograde and antegrade pyelograms revealed bilateral midureteral stricture, idiopathic retroperitoneal fibrosis at first suspected, but no mass in the retroperitoneal space was found by a computed tomogram. An exploratory laparotomy showed no fibrous mass in the retroperitoneal space either, but that the wall of the ureter was thickened. Biopsy of the ureter led to a histological diagnosis of fibrosis. Since evidence of inflammation such as elevation of the erythrocyte sedimentation rate and cross-reacting protein was found, 50 mg of prednisolone has been administered every other day, with the result that inflammation is now under control. This report deals with specific ureteral fibrosis related to idiopathic systemic fibrosis and collagen disease.

A 60-year-old man presented with sudden palpitations in September 1993, and was admitted to hospital with a diagnosis of atrial fibrillation and heart failure. The patient was suspected of having collagen disease, because of a positive test for antinuclear antibodies and a high sedimentation rate. He was referred to lou hospital. Chest radiographic findings were suggestive of cardiomegaly and cardiac murmurs were audible, which indicated the presence of heart disease. A chest Ct scan revealed a lesion surrounding the intramediastinal large vessels and the heart from the level of the confluence of the left brachiocephalic vein and the superior vena cava. Suspicion of a mediastinal tumor led the patient to be admitted to the respiratory department. Percutaneous needle biopsy with a Trucut needle revealed non-specific chronic inflammation. An abdominal CT scan showed that the lesion surrounding the descending aorta traversed the diaphragm, reached the renal pelvis along both renal arteries, and caused narrowing of the ureter and left hydronephrosis. Based on these findings, retroperitoneal fibrosis was diagnosed. Treatment with steroids caused the lesion to shrink.
