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-week 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 and posterior urethral valves. He underwent a posterior urethral valves ablation and removal of the migrated shunt.
