Congenital scaphoid megalourethra: report of two cases.

Congenital megalourethra is a rare congenital malformation of the penile urethra. It is defined as the diffuse dilatation of the anterior urethra due to the absence of development of the erectile tissue of the penis. Since the initial description, nearly 80 cases with megalourethra have been reported in English literature. Congenital megalourethra has been classified into scaphoid and fusiform types and is usually associated with additional urinary tract and other system anomalies, irrespective of its type and severity. We report two rare cases of scaphoid megalourethra without any associated anomaly. A 13-year-old boy and an 8-month-old boy were admitted to the Department of Pediatric Surgery with complaints of penile swelling and dysuria since birth. Physical examination and retrograde cystourethrogram confirmed the diagnosis of congenital scaphoid megalourethra. Both patients underwent a reduction urethroplasty. They did well postoperatively and voided with a normal stream without any abnormality of the penile shaft.
