Enteropathy induced by non-steroidal anti-inflammatory drugs.

volume.Of the over 200 fetuses with bilateral hydronephrosis we evaluated, only five met the prenatal diagnostic criteria for open fetal surgery.Three fetuses had return of normal amniotic fluid dynamics, and all three survived the neonatal period and had adequate pulmonary function.Our prenatal diagnostic and selection criteria have greatly improved, and fetal intervention for congenital bilateral hydronephrosis is capable of reliably decompressing the obstructed urinary tract, restoring amniotic fluid dynamics, and preventing otherwise fatal pulmonary hypoplasia.Whether in utero decompression reverses or arrests dysplastic changes in the kidneys and prevents long term renal failure remains an open question.
