RESUMO
A literatura relata somente alguns casos de recém-nascidos com ascite urinária, geralmente secundária a ruptura de bexiga urinária e não de um cálice renal. Este relato de caso descreve um caso raro de ascite urinária em recém-nascido com válvula de uretra posterior que teve ruptura de um cálice renal, neste caso diagnosticada, até onde sabemos, pela primeira vez por ultrassonografia.
The literature reports only rare cases of urinary ascites, usually secondary to rupture of the bladder and not to renal calyx rupture. The present report describes an uncommon case of posterior urethral valve in a newborn with ascites caused by the rupture of a renal calyx that, to our knowledge, was diagnosed for the first time by ultrasonography.

Urinary ascites in newborns is a rare event that usually is associated with posterior urethral valves and other obstructing anomalies of the genitourinary tract. A case of neonatal urinary ascites without genitourinary tract abnormalities is reported. This premature male neonate was treated by artificial ventilation due to respiratory distress syndrome. The umbilical artery catheter was placed without difficulties and functioned well until removal. Periumbilical leak of urine was not observed. He showed abdominal distension and oliguria on second postnatal day. He was found to have ascites, hyponatremia and elevation of BUN content disproportionate to the mild elevated serum creatinine value. Radiological examination revealed normal genitourinary tract except intraperitoneal extravasation of contrast material from the bladder. Conservative management resulted in complete resolution of the lesion in this patient.

Spontaneous intraperitoneal extravasation of urine is rare. Urinary ascites occurs mostly in patients with the common primary obstructive lesion being posterior urethral valves. The second most common cause of urinary ascites is hydronephrosis due to congenital ureteropelvic junction obstruction. We report a case of urinary ascites with urinoma resulting from a ureteropelvic junction obstruction in an infant.
