Management of ureteropelvic junction obstruction in neonate.

Fetal hydronephrosis demonstrated by maternal ultrasonography should lead to early investigation during the neonatal period. Postnatal confirmation of the diagnosis of ureteropelvic junction obstruction usually can be established by combining the radiologic modalities of ultrasound, diuretic isotope renal scan, and voiding cystourethrography. Rarely should intravenous urography, antegrade pyelography, or cystoscopy and retrograde pyelography be necessary. Findings of high-grade obstruction and/or significantly diminished function on the affected side(s) should prompt early neonatal reconstruction. Pyeloplasty was performed within the first month of life in 17 infants (20 kidneys) diagnosed as having significant ureteropelvic junction obstruction. Early reconstruction in the neonatal period can be performed successfully with minimal complications and a relatively brief period of hospitalization. This may ultimately achieve maximal preservation of renal function.
