Persistent Anhydramnios and LUTO in a Patient with a Vesicoamniotic Shunt.

Persistent anhydramnios after placement of a vesicoamniotic shunt is a rare but potentially serious concern in a patient in utero. We present the case a male fetus who at 32 weeks gestation had bilateral hydroureteronephrosis, a distended bladder, and anhydramnios. A vesicoamniotic shunt was placed, but the anhydramnios persisted. Postnatally, the child was found to have a migrated shunt, left grade V vesicoureteral reflux (VUR) and posterior urethral valves (PUV). He underwent a PUV ablation and removal of the migrated shunt. The patient is now two years old and is doing well with no urinary tract infections or renal deterioration.
