Prune belly syndrome with penile and urethral agenesis: report of a case

The authors report the case of an infant born with prune belly syndrome associated with penile and urethral agenesis. At 15 weeks' gestation, antenatal ultrasonography showed a fetal giant bladder, congenital hydronephrosis, and oligohydramnios, and at 17 weeks' gestation, a fetal vesicoamniotic shunt operation was performed. A boy was born at 33 weeks' gestation with prune belly syndrome, an anocutaneous fistula, and penile agenesis. A cystostomy and cut-back operation were performed immediately, showing urethral agenesis, no urethral opening, and left renal hypoplasia. Thereafter, his renal system began functioning normally, and a urinary tract infection resolved. The authors speculate that the prune belly syndrome in this patient was caused by penile and urethral agenesis.
