Progress of diagnosis and treatment of fetal and newborn lower urinary tract obstruction

Abstract

Congenital lower urinary tract obstruction in the fetus and is rare in neonates, but it is identified increasingly in the era of prenatal sonography and resulted in substantial perinatal mortality with lifelong morbidity.Posterior urethral valves, urethral atresia, and prune-belly syndrome are the frequently reported causes of lower urinary tract obstruction.Despite the completion of a randomized trial, the benefit of prenatal intervention with vesicoamniotic shunt placement remains unclear.The management of these disease in fetus and newborns requires appropriate urinary tract decompression, subspecially support, and definitive diagnosis with endoscopy and radiography.Now, the recent progress of diagnosis and treatment of congenital lower urinary tract obstruction were reviewed.
