title: Spontaneous resolution of apparent radiation associated retroperitoneal fibrosis.
abstract: A 70-year-old man was diagnosed with retroperitoneal fibrosis (RPF) complicated by ureteral obstruction 4 months after finishing radiotherapy for prostate cancer. He was treated conservatively with ureteral stent placement. After 3 months, computed tomography scan of the abdomen revealed resolution of RPF without any medical or surgical interventions. Although an uncommon event, the possibility of spontaneous resolution of RPF, as demonstrated by this and previously reported cases, has led some to encourage conservative management.
