Introduction And Importance: Retrocaval ureter (RCU) is a rare congenital anomaly usually associated with upper urinary tract stasis, in which the ureter itself passes behind the inferior vena cava. RCU is often misdiagnosed and can lead to serious complications related to the upper urinary tract stasis.
Case Presentation: We report the case of a 57-year-old female who presented with 1-year history of intermittent right flank pain, of gradual onset.
