[Treatment of idiopathic retroperitoneal fibrosis]

Idiopathic retroperitoneal fibrosis is a rare disease and a delay in diagnosis may cause renal failure. Medical treatment i.e. corticotherapy or more recently, tamoxifene has been used successfully. This approach is recommended in patients either with moderate obstruction of the upper urinary, risk of major surgery or in cases of recurrence after surgical treatment. Ureterolysis using conventional surgery or laparoscopy remains the treatment of choice. This procedure should be considered in patients with neoplasic fibrosis, corticoresistant fibrosis or in cases of peri-aneurysm fibrosis.
