Ureteral advancement in patients undergoing laparoscopic extravesical ureteral reimplantation for treatment of vesicoureteral reflux.
OBJECTIVE
Laparoscopic extravesical ureteral reimplantation for vesicoureteral reflux has gained acceptance as a feasible treatment associated with minimal morbidity. However, ureteral advancement with this technique has not been attempted. We examined the usefulness of ureteral advancement via laparoscopy.


METHODS
A total of 30 patients with 51 refluxing ureters underwent laparoscopic extravesical ureteral reimplantation for treatment of vesicoureteral reflux between August 2009 and September 2011. Mean ± SD patient age was 60.8 ± 48.6 months. During the procedure 15 patients underwent ureteral advancement (advancement group), while 15 did not (nonadvancement group). We compared operative times and postoperative rates of urinary tract infections and persistent reflux between the groups.


RESULTS
There was no significant difference in operative times in unilateral (mean ± SD 110 ± 25 vs 125 ± 42 minutes) and bilateral cases (mean ± SD 214 ± 52 vs 203 ± 40 minutes) between the nonadvancement vs advancement groups. All patients underwent voiding cystourethrography 3 to 4 months postoperatively. Reflux resolution rate for ureters was significantly higher in the advancement group (100%) than in the nonadvancement group (85%, p <0.05). No patient in the advancement group had postoperative urinary tract infection. Fixation of the ureter with the bladder muscularis at the proximal limit of the detrusor defect and/or a percutaneous hitch stitch placed in the ventral side of the proximal limit of the detrusor defect facilitated ureteral advancement.


CONCLUSIONS
Ureteral advancement is a simple and feasible procedure in laparoscopic ureteral extravesical reimplantation and may improve the resolution rate of vesicoureteral reflux.
