Urethral Calculi in a 7-Year-old Boy Presenting as a Large Scrotal Mass After Surgery of Exstrophy-epispadias Repair.

Urethral calculi are extremely rare in pediatric population and are usually presented with dysuria, hematuria, lower urinary tract obstruction, and rarely as a scrotal mass. We here report a giant primary urethral stone presenting as a scrotal mass that developed in the penile urethra resulting from a postsurgical complication of exstrophy-epispadias repair. A 7-year-old boy was admitted with the complaint of scrotal mass and dysuria. Computerized tomography confirmed giant urethral stone impacted to diverticulum of urethra. Cystoscopy revealed a nonobstructed stone in the urethra related to a posterior diverticulum. After scrotal incision, stone was removed with open diverticulectomy.
