MIS Management of Posterior Urethral Valves (PUV)
Posterior urethral valves (PUV) are the most common cause of bladder outlet obstruction in children. They occur in 1/5000–25,000 live births and constitute 10% of urinary obstruction diagnosed in utero [1–4]. PUV are associated with high fetal and neonatal mortality (30%) and considerable lifelong morbidity. The morbidity is related to the congenital obstruction of the urinary tract at the critical time in organogenesis which may have a profound and lifelong effect on kidney, ureter, and bladder function . In severe cases, the disorder can lead to anhydramnios and pulmonary dysplasia during the canalicular phase of lung development. Mortality is related to ongoing renal damage in children.
