Prenatal Ultrasonographic Diagnosis of Posterior Urethral Valve: A Case Report

Abstract

A case report on prenatal ultrasonographic diagnosis of posterior urethral valve. Several anomalies of lower urinary tract leading to obstructive uropathy have been demonstrated in literatures either isolated of urethra or in combination with other syndromes like Prune-belly syndrome or anorectal malformation. In this present case report, we would like to elucidate the prenatal ultrasonographic features of posterior urethral valve (PUV) and formulate a brief discussion on the treatment option including prognosis of such a case. This case was detected incidentally by routine ultrasonographic examination of foeto-placental profile to monitor growth of the foetus. Mother was counselled for prenatal treatment but she opted for immediate postnatal treatment. Foetal surgery of such type of cases has not been reported much. It is associated with high risk of preterm delivery. Here we have diagnosed it in prenatal period and managed this case after delivery at 34 weeks of gestation.
