Abstract:
Objective To investigate the clinical outcome of modified laparoscopic extravesical ureteral reimplantation for primary obstructive megaureter(POM).Methods A retrospective analysis was made on 11 cases of POM treated with modified laparoscopic extravesical ureteral reimplantation(Lich-Gregoir method)from December 2020 to October 2023.The patients were aged from 7 months to 10 years and 5 months old(mean,57.6±41.9 months).Intraoperatively,a tunnel was created longitudinally from the posterior bladder wall and the ventral end of the new tunnel was used as the ureteral anastomosis.Results All the 11 laparoscopic operations were successful with no intraoperative complications and no conversions to open surgery.The operation time was 105-145 min(mean,125.5±13.9 min).The 11 cases were followed up for 4-25 months(mean,16 months).None of them had difficulty in urination or urinary tract infection.The distal ureter maximum diameter and hydronephrosis were significantly reduced at 3-6 months after surgery than those before surgery[the distal ureter maximum diameter reduced from(23.0±10.0)mm to(5.2±3.4)mm(P=0.000),and the maximal separation value of the renal collecting system reduced from(35.2±21.1)mm to(11.6±6.9)mm(P=0.001)].Conclusion Modified laparoscopic extravesical ureteral reimplantation is easy to perform and can be one of the treatment options for primary obstructive megaureteropathy in children.
