Background: Urinary ascites is often associated with either rupture of calyceal fornixes, ureter or urinary bladder secondary to distal renal tract obstruction. Prostatic utricle cyst is usually asymptomatic, rarely presents in neonatal period as neonatal ascites. Case Description: Term male infant, with antenatal presentation of cystic structure posterior to the urinary bladder, was born with gross neonatal ascites. Postnatal workup confirms diagnosis of perforated prostatic utricle cyst as the cause of isolated urinary ascites. Child was managed with serial abdominal paracentesis and temporary vesicostomy followed by surgical removal of cyst at later date. Discussion: Fetal and neonatal ascites is caused by diverse etiologies and requires a broad-based antenatal and postnatal approach in determining its underlying cause. Neonatal urinary ascites occurs commonly due to obstructive uropathies with perforation of prostatic utricle cyst a rare presentation. Peritoneal fluid examination and radiological investigations like ultrasound, MRI and cystoscopy can help to confirm the exact cause of urinary ascites. Basic aim of management of neonatal urinary ascites includes abdominal decompression, urinary drainage with or without vesicostomy or surgical repair of perforation site. Prognosis depends on the age, amount of ascites, degree of compression and extent of changes in urinary tract.
