Ureterocele is a cystic dilatation of the distal ureter and is a rare cause of urinary tract obstruction. It is commonly found in infants and young children and is more prevalent in females than in males. This report presents the case of a 59-year-old woman who suffered right flank pain and was diagnosed with ureterocele. The patient was treated with endoscopic surgery and unroofing of the ureterocele.
