We present a case of in-utero treatment of posterior urethral valve syndrome(PUVS) by vesicoamniotic shunting. The shunt was established by basket-shaped catheter at the 22 weeks' gestation. Enlarged bladder and hydronephrosis were improved after the shunt procedure. The baby was delivered at the 39 weeks' gestation and had normal serum range of BUN and creatinine. Because the outer opening of catheter was burried under abdominal skin on the day before delivery, posterior urethral valve excision and basket removal through urethra were operated by endoscopy on the 2nd day of birth. The baby has been followed up for 5 months and in good health. We report this case with a brief review of literature. Shunt operation in-utero is considered as a safe and effective therapy for lower urinary tract obstruction caused by PUVS.
Key Words: Posterior urethral valve syndrome(PUVS), vesicoamniotic shunt, basket-shaped catheter
