[Giant urethral lithiasis].

Calculi in the male urethra are rare and are generally associated with urethral disorder (diverticuli, stricture, complication posturethroplasty, etc.). Treatment is generally by excision and resolution of the underlying cause. We report a case of urethral calculus, of apparently idiopathic etiology, that had treated by endoscopic ultrasonic disruption. The importance of preoperative etiologic diagnosis is underscored.
