Volume 8, Number 4Reviews in UrologyRobotic Ureterolysis, Retroperitoneal Biopsy, and Omental Wrap for the Treatment of Ureteral Obstruction Due to Idiopathic Retroperitoneal FibrosisCase ReviewPatrick W MufarrijMichael D StifelmanRetroperitoneal fibrosis (RPF) is a rare disorder of unclear etiology characterized by chronic inflammation of the retroperitoneum, which can involve any of the retroperitoneal structures, most notably the ureters, aorta, and vena cava. Historically, open biopsy, ureterolysis, and transpositioning or omental wrapping of the involved ureter(s) have been the preferred surgical treatments of RPF, with success rates greater than 90%. More recently, successful laparoscopic biopsy, ureterolysis, and ureteral omental wrapping and intraperitonealization have been described. We report the first case in the literature of idiopathic RPF managed with robotic ureterolysis and laparoscopic omental ureteral wrapping.

Volume 16, Number 2Case ReviewImmunoglobulin G4–related Retroperitoneal Fibrosis of the PelvisAnthony DyerPeter M SadowErika BracamonteMatthew GretzerRetroperitoneal fibrosis (RPF) is a rare disease characterized by the replacement of normal tissue with fibrosis and/or inflammation. In this case, a 68-year-old man presented with RPF in the pelvis, a rare location for this disease. Biopsies were performed, which showed elevated levels of C-reactive protein, erythrocyte sedimentation rate, and, most importantly, immunoglobulin G4 (IgG4). It has been postulated that IgG4-related sclerosing disease is a systemic disease. Treatment has been successful with systemic corticosteroids.
