Successful vesicoamniotic shunting of posterior urethral valves in the first trimester of pregnancy.

Abstract

Prenatal ultrasonography early in gestation allows diagnosis of posterior urethral valves. We report on a fetus with posterior urethral valves treated using vesicoamniotic shunting at 13 + 5 weeks' gestation. A double-basket catheter was used for shunting. A 2582-g male neonate was delivered at 33 weeks' gestation, and the infant continued to show normal renal function at 3 years of age. To the best of our knowledge this is the first report of successful vesicoamniotic shunt placement using a double-basket catheter in the first trimester of pregnancy.
