A 30-year-old man, who underwent urethroplasty for hypospadias at three years of age, visited a hospital complaining of scrotal induration and terminal dribbling. Magnetic resonance imaging for assessing this induration revealed a 3-cm subscrotal mass. Thereafter, the patient was referred to our department for further evaluation. Scrotal ultrasonography demonstrated a well-circumscribed mass with acoustic shadowing. Based on image findings of ultrasonography, computed tomography, and urethrography, he was diagnosed with urethral stone in the neourethra. Since it was impossible to perform transurethral lithotripsy owing to severe meatal stenosis, this urethral stone was removed by meatotomy and incising a part of the patient’s neourethra. Urethral stone is recognized as one of the late complications after urethroplasty for hypospadias. Urethral stricture, diverticulum, and hair are causes of urethral stone following hypospadias repair. In this case, scrotal ultrasonography was an important and useful modality for us to strongly suspect that the subscrotal mass was a huge urethral stone.
