Ureteropelvic junction (UPJ) obstruction is by far the most common cause of pediatric hydronephrosis, occurring in 1 per 1000-2000 newborns. Laparoscopic pyeloplasty, first introduced in adults in 1993 by Schuessler, yields results that are comparable with those of open pyeloplasty, with success rates reported to be as high as 96-98%, while still maintaining the benefits of endoscopic approaches, including less postoperative pain, short hospitalization, and reduced postoperative recovery time.
