Background: Although corticosteroids (CS) are used primarily in idiopathic retroperitoneal fibrosis (iRPF), tamoxifen (TMX) may be a suitable alternative. We compared outcome with CS or TMX monotherapy for first presentation in a large group of patients with iRPF disease.
Methods: Of all patients with iRPF disease who were seen at our tertiary care referral centre from February 1999 to December 2011, 118 patients were eligible for this retrospective study.
