The authors describe a 20-year-old man who was hospitalized for anemia and frequent attacks of right flank soreness. Right hydronephrosis was found incidentally on ultrasound. Renal scintigraphy revealed a urinary leak into the colon as a result of an unsuspected ureteroenteric fistula. The diagnosis of pyeloduodenal fistula was confirmed by retrograde pyelography.
