title: Spontaneous regression of bilateral hydronephrosis due to retroperitoneal fibrosis.
abstract: The case was a 73-year-old male who presented with bilateral hydronephrosis due to retroperitoneal fibrosis. Later he became anuric and nephrostomy was constructed. However, with no medical treatment, the hydronephrosis disappeared. Such a spontaneous regression is rare and the etiology is discussed.
