Diagnostic evaluation of neonatal ascites

Area of Science:

• Neonatal surgery
• Pediatric urology
• Fetal medicine

Background:

• Posterior urethral valves (PUVs) are a common cause of bladder outlet obstruction in male infants.
• Intraperitoneal bladder rupture is a rare but serious complication of severe PUVs, often presenting antenatally.

Observation:

• A premature infant exhibited massive abdominal distension at birth.
• Obstetric ultrasound revealed abdominal distension, oligohydramnios, and restricted chest wall motion.

Findings:

• The infant was diagnosed with posterior urethral valves.
• Intraperitoneal rupture of the bladder was identified as the cause of the massive distension.

Implications:

• This case highlights the importance of antenatal diagnosis of posterior urethral valves.
• Prompt recognition and surgical intervention are crucial for managing bladder rupture in neonates.
• Understanding this rare complication aids in improving outcomes for affected infants.
