Abstract

The widespread use of antenatal ultrasonography has resulted in an increasing number of newborns being diagnosed with hydronephrosis. In general, the potential of recovery in an obstructed kidney detected by maternal antenatal ultrasonography cannot be predicted by the currently available diagnostic means. Thus the urgency,safety and benefits of performing pyeloplasty in neonates currently are being questioned. To evaluate the anesthesiologic risk and the surgical morbidity of pyeloplasty in premature and mature neonates with hydronephrosis requiring surgical correction, the premature and mature neonates who underwent surgical correction were classified into 3 groups. First two groups are the infants under and beyond 1 month of age who underwent an operation without preliminary percutaneous nephrostomy and the third group is composed of the infants who underwent corrective surgery one month after preliminary percutaneous nephrostomy which was performed during neonatal period. There was no remarkable difference in anesthetic time, operation time, duration of postoperative hospital day and surgical complication among groups. The surgical results in all except 1 case showed the definite morphological and functional improvement of kidney. Pyeloplasty in premature and mature neonates is a safe and successful procedure for presentation of renal function as the procedure performed in older age group.
