Antenatal fetal hydronephrosis

Antenatal fetal hydronephrosis

Hydronephrosis /uni00A0 – /uni00A0 a dilated renal pelvis /uni00A0 – /uni00A0 is found in 1% of - antenatal scans and most commonly it resolves, especially if the dilatation is mild to moderate. Severe dilatation is asso - ciated with urinary tract obstruction or vesicoureteral reflux. Antenatal interventions are rarely indicated except in posterior urethral valves (PUVs), but postnatal imaging is needed to confirm resolution or make a diagnosis. Amniotic fluid is prin - - cipally fetal urine; thus , if there is antenatal bilateral hydro - nephrosis with decreased amniotic fluid, PUV is a likely cause. If the PUV obstruction is thought to be damaging the kidneys, then there may be a role for an antenatal v esicoamniotic shunt to take the pressure o ff the upper tracts.
