Therapeutic effect of laparoscopic ureteral end-to-side anastomosis at pelvic level for duplication of ureter / 中华实用儿科临床杂志

ABSTRACT

Objective To study the therapeutic effect of laparoscopic ureteral end-to-side anastomosis at pelvic level for duplicate ureteral malformation.Methods Clinical data of 10 children with unilateral ureteral duplication,who received laparoscopic ureteral end-to-side anastomosis at pelvic level at Department of Urology,Affiliated Children's Hospital of Nanjing Medical University from September 2016 to November 2017 were reviewed.There were 6 boys and 4 girls with an average age of 13.9 months(1 month and 21 days to 3 years and 9 months).Ultrasonography,intravenous pyelography and magnetic resonance urography were performed before surgery.There were 6 cases of duplication with hydronephrosis in the upper moiety.The rest 4 cases were complicated with ureteroceles.Presentations included urinary dripping and symptoms caused by urinary tract infections.Urine test,ultrasonography,intravenous pyelography were performed during the 3-16 months follow-ups for all the patients after surgery.Results The laparoscopic ureteral end-to-side anastomosis was performed successfully in all patients at the pelvic level,the average operating time was 98 minutes (60-125 minutes) and mean hospital stay was 7.3 days(7-8 days).All the presentations disappeared after surgery.All the patients were followed up for 3 to 6 months with relieved hydronephrosis.Postoperative examination of intravenous pyelography in 10 cases showed that there was no anastomotic obstruction.Conclusions The laparoscopic ureteral end-to-side anastomosis can be used for duplicate ureter,and it is a safe and effective method for the treatment of ureteral duplication.
