Neonatal obstructive uropathy is the leading cause of renal failure during infancy. A variety of upper and lower genito-urinary (GU) tract disorders may cause obstructive uropathy. The prompt diagnosis and evaluation of obstructive uropathy is imperative since appropriate intervention and follow-up can lead to excellent early recovery of function. The role of in utero diagnosis is primarily to alert physicians to the presence of obstructive uropathy and permit rapid initiation of care at birth or earlier in certain instances. The GU tract must be evaluated for evidence of dilatation, for reflux and for renal function using radionuclide studies, voiding cystourethrograms, cystoscopy and pyelography. The early course of neonatal obstructive uropathy has been improved by institution of GU diversion and primary repair, yet the effect of early surgical intervention and medical therapy in preventing renal failure remains unclear. Further studies are needed to identify prognostic features heralding progression to renal failure and how such progression can be prevented.
