Congenital megalourethra

Megalourethra, a rare congenital disorder involving the anterior urethra, is subdivided into two types: Fusiform and scaphoid. Two cases of scaphoid type megalourethra are reported. The first patient, a 5-weeks-old infant diagnosed at birth as having the prune belly syndrome was admitted to the hospital with vomiting and failure to thrive. Intravenous pyelogram revealed marked dilatation of the left ureter and a bladder diverticulum. A penile urethrostomy was performed. The second patient, born to healthy parents after an uneventful pregnancy and delivery, was found to have an enlarged and deformed penis. The baby voided with a poor stream and a concomitant swelling of the penis was noted. Retrograde uretrography showed a sac-like dilatation of the penile urethra. Surgical revision was carried out a 2 stage procedure and was completed (Nesbitt's operation) after 4 months. The patient did well postoperatively and voided with a normal stream without any abnormality of the penile shaft.
