Scaphoid megalourethra with multiple urogenital anomalies.

A male infant with scaphoid megalourethra, which is a rare congenital anomaly, is presented. At birth he exhibited a grossly swollen, malformed penis and cryptorchidism. The corpus spongiosum was not palpable. The infant had congenital renal failure. Retrograde urethrography revealed a crescent-shaped dilatation of the anterior urethra, and the diagnosis of scaphoid megalourethra was made. Subsequent uroradiological examinations showed that there were also severe urogenital anomalies, i.e. renal hypoplasia-dysplasia, hydronephrosis, hydroureter and vesicoureteral reflux. This disorder is frequently associated with other urogenital anomalies. Therefore, once the diagnosis is reached, a careful investigation for other associated abnormalities should be undertaken.
