[corrected] Idiopathic retroperitoneal fibrosis (IRF) is an uncommon disease characterized by a retroperitoneal fibrotic tissue that often involve the ureters, leading to the obstructive nephropathy and variable impairment of renal function. Findings strongly suggest an autoimmune etiology. Surgery, medical treatment with immunosuppressive drugs, or a combination of both are proposed. The optimal treatment has not been established yet. The aim of this study was to present our experience with combined immunosuppressive therapy of IRF, steroids (S) and mycophenolate mofetil (MMF). ⋯ The combination of steroids and mycophenolate mofetil led to the remission of IRF with a strong and quick immunosuppressive effect. It also provided avoiding the long-term use of high steroid dose and surgical procedures.
