[Idiopathic retroperitoneal fibrosis].

Abstract

Idiopathic retroperitoneal fibrosis is generally held to be uncommon. Its etiology is unknown. The disease continues to present with early bilateral ureteric involvement. Nowadays imaging techniques permit so a timely diagnosis to preserve and reduce renal damage. The optimum method of management is still controversial. Controversies on pharmacological, endourological and surgical treatment are debated. The advantages of various types of surgery are reviewed. In the urological department of the Civic Hospital in Brescia from February 1984 to June 1992, 87 patients (6 females and 2 males) with IRP were observed. Surgical treatment was combined with corticosteroids in 6 patients. Ureterolysis was performed with omental wrapping in 5 patients, with ureteric intraperitonealisation in 2 other ones. In the last case an ileal loop replacement was performed. In 5 out of 8 patients the ureteral stricture was resected and a termino-terminal anastomosis was necessary. Long-term follow-up is satisfactory. The authors conclude that omental wrapping is the safest method of choice.
