CONTEMPORARY TRENDS IN SURGICAL CORRECTION OF PEDIATRIC URETEROPELVIC JUNCTION OBSTRUCTION: DATA FROM THE NATIONWIDE INPATIENT SAMPLE

Practice patterns in pediatric pyeloplasty evolved between 1988 and 2000. Fewer procedures are being performed in newborns, suggesting that patients with prenatal hydronephrosis are increasingly being observed instead of undergoing early surgery. There was a substantial difference in timing of surgery between whites and nonwhites. To our knowledge this observation has not previously been reported. More procedures are being performed at teaching hospitals, and length of stay has decreased significantly.
