Bladder calculi are a common late complication of bladder augmentation with a reported incidence of 10% to 50%, but scrotal calculi are rare. Here we report a patient with augmented bladder who was operated for huge bladder calculi and multiple scrotal calculi, considered to develop due to bladder neck repair. The patient with prior reconstruction for extrophy-epispadias complex in the newborn period underwent sigmoid augmentation and Mitrofanoff stoma formation in the age of nine. At the age of 17, he was admitted to the hospital for macroscopic hematuria, presence of stones in the scrotum, and urine coming out of his scrotum. On physical examination, multiple scrotal stones and a scrotal fistula with a stone in its outer opening were noticed. The patient was operated for bladder and scrotal calculi. The stones, six of which were over 4 cm, were removed. Bladder calculi is a common complication after augmentation cyctoplasty, however with irregular follow up and treatment, scrotal stone formation may occur as a rare complication.
