Congenital megalourethra and posterior urethral valve in a patient with Down syndrome.

Megalourethra is a rare congenital anomaly of the urethra that develops as a consequence of dysgenesis of the corpus cavernosum and corpus spongiosum. Herein, we present three congenital abnormalities in one newborn ie; Down syndrome, posterior urethral valve (PUV) and scaphoid megalourethra. The patient was treated successfully by ablation PUV and reduction uretrophlasty. The postoperative period was uneventful and the renal functions could be preserved in the long term.
