Current concepts in the perinatal diagnosis and management of hydronephrosis.
Perinatal urology has become a significant facet of pediatric urologic practice. This article reviews the approaches to the diagnosis of prenatal hydronephrosis and its typical sonographic appearances in relation to the underlying pathology. A review of the outcomes of prenatal uropathology serves as a basis on which to interpret reports of prenatal intervention for hydronephrosis. A critical review of the experience of prenatal intervention is conditionally supportive of its benefits, but this view must be tempered by a recognition of the inherent risk to the mother and fetus. Included within this view is a recognition that not all hydronephrosis is caused by obstruction. More specific prognostic indicators of renal and pulmonary functional reserve are critically needed to permit appropriate patient selection. This must be coupled with more rigorous assessment of outcomes and complete reporting of the results. Continued basic and clinical research is important in developing these data. A management strategy for hydronephrosis in the prenatal and postnatal periods is presented, based on the goal of permitting maximal renal as well as pulmonary development in utero and in the newborn period.
