Ureteropelvic junction (UPJ) obstruction remains the most common cause of hydronephrosis in newborns and children.Open pyeloplasty has been the gold standard for management of UPJ obstruction in these patients. We report our technique and outcome with laparoscopic transperitoneal dismembered pyeloplasty in children. PATIENTS AND METHODS: Nineteen patients, ages 2 to 14 years, underwent laparoscopic pyeloplasty at our center between June 2004 and December 2006. Thirteen pyeloplasties were on the left side and six on the right side. A transmesocolic approach was used in five left-sided UPJ obstructions. All operations were performed by the transperitoneal route using either three or four ports. RESULTS: Sixteen patients underwent dismembered (Anderson-Hynes) pyeloplasty, while three had a nondismembered Foley's Y-V pyeloplasty. Mean operative time was 198 minutes (range 105-300 min). Mean estimated blood loss was 45 mL (range 30-130 mL). Mean length of stay was 4 days (range 3-5 d). Mean followup was 13.8 months (range 2-30 mos). Postoperatively, one child had a urinary tract infection that necessitated hospital admission and administration of intravenous antibiotics. Eighteen of 19 patients demonstrated improved drainage with no evidence of obstruction on diuretic renography and/or excretory urography. One patient is awaiting follow-up. There was no conversion to open surgery. CONCLUSION: Laparoscopic pyeloplasty in children is a safe, minimally invasive treatment option that duplicates the principles and techniques of definitive open surgical repair. It is technically challenging; with increasing expertise, operative times are reduced significantly.
