Neonatal ascites and oligohydramnios: the role of kidney

Abstract

Posterior urethral valve pathologies are the most frequent childhood obstructive uropathy reported, and we infer their presence on diagnosing foetal ascites and oligohydramnios. Early action is vital to determine the long-term development and the degree of impairment of renal function. We report a newborn male 34 weeks of gestation with a prenatal diagnosis of foetal ascites, fluid on the loose in renal fossa and oligohydramnios. Subsequent studies have shown the presence of posterior urethral valves with associated significant vesicoureteral reflux. There was no secondary renal damage. Intrauterine decompression of the urinary tract seems to have exerted a protective role against kidney damage. This finding supports the role of foetal decompression surgery in early and severely obstructive forms to improve the prognosis of renal function in the long term.
