“…The first case of pre-natal PBS diagnosis dates from 1977, when an enlarged bladder was detected at 20½ weeks of gestation 23. Currently, ante-natal diagnosis of PBS became feasible at around 12 weeks of gestation due to the sophistication of the ultrasonographic equipment.…”

Prune-belly syndrome (PBS) is a rare congenital anomaly characterized by a spectrum of mild-to-severe presentations of urinary tract malformations, deficient abdominal wall musculature, and cryptorchidism in male newborns or genital abnormalities in the female newborns. Currently, antenatal diagnosis is feasible with ultrasound examination, and treatment is based on case report experience. More recently, intrauterine management has been undertaken with encouraging results. The authors report a case of PBS diagnosed at the seventeenth gestation week, when ultrasonographic examination revealed the presence of ascites, distended bladder, thickened bladder wall and posterior urethral valve. The fetus was submitted to an intrauterine intervention at the nineteenth gestational week. Delivery occurred at 34 weeks of gestation and the newborn examination was consistent with PBS. On the second day of life, the newborn was submitted to abdominoplasty, colostomy, and orchiopexy. However, the outcome was unfavorable with respiratory failure and death on the fifteenth day of life. The autopsy confirmed the diagnosis of PBS, but the immediate cause of death was attributed to aspiration pneumonia.

An opportunity recently arose to treat in utero, with the aid of real-time ultrasound, a fetus affected with urinary outflow tract obstruction. This report documents that attempt at treatment and elucidates the constituents of fetal urine obtained at various gestational ages. CASE REPORTA 22-yr-old woman, gravida 2, para 0, abortion 1, with a last menstrual period of 6/22/80 and an EDC of 3/29/81 had an uncomplicated prenatal course until 26 wk gestation, when an ultrasound examination was performed because of a sizedate discrepancy. Findings at this examination revealed a single fetus in the vertex presentation, a biparietal diameter of 63 mm (26 wk gestation), normal amniotic fluid volume, bilateral hydronephrosis, and a large cystic abdominal mass displacing the bowel superiorly and laterally (Fig 1). The abdominal wall was quite thin. The presumptive diagnosis was urinary outflow tract obstruction and prune belly syndrome. To prevent potential damage to the renal and pulmonary systems, it was thought that the pressure of the distended bladder should be relieved.With continuous guidance by real-time ultrasound, direct placement of a 20-gauge spinal needle into the fetal bladder was performed and 340 ml of fetal urine was removed. The bladder drainage was repeated one week later, with removal of 310 ml of fetal urine. Seven days later, fetal ascites was noted, and the bladder was less distended (Fig 2). Fetal ascitic fluid was removed totaling 320 ml, and 50 ml of fetal urine was also
