AB068. Transperitoneal laparoscopic dismembered pyeloplasty for ureteropelvic junction obstruction in children

BACKGROUND: To explore the clinical value of transperitoneal laparoscopic dismembered pyeloplasty for ureteropelvic junction obstruction (UPJO) in children. METHODS: The clinical data of 28 cases with UPJO were respectively reviewed. Among the cases, 19 cases were male and 9 cases were female. Their ages ranged from 8 to 14 years old. The diagnosis was set up by color ultrasonography and CTU and MRU. All the cases had hydronephrosis, with 10cases moderate, 18 cases severe. Twenty-eight patients with UPJO underwent transperitoneal laparoscopic dismembered pyeloplasty. RESULTS: All the operations were performed successfully, without conversions to open surgery. The average operation time was 120 minutes (range, 90–210 minutes), the average blood loos was 15 mL (range, 10–25 mL), and the postoperative hospital stay was 8 days (range, 6–11 days). Two cases occurred urinary leakage and recovered 7 and 50 days later respectively. Twenty-six cases were followed-up for 3 to 36 months, examined by color ultrasonography or CTU or MRU. Two cases occurred ureteral stenosis and cured by ureteroscopic needle electrode. Hydronephrosis disappeared in 10 cases, decreased in 12 cases, stabilized in 2 cases. CONCLUSIONS: Transperitoneal laparoscopic dismembered pyeloplasty could be a mini-invasive, effective, and easy operating procedure for the treatment of UPJO in children.
