[Application of robotic-assisted versus conventional laparoscopy in ureteral reimplantation with psoas hitch].

Abstract

OBJECTIVE: To compare the efficacy of robotic-assisted laparoscopic and conventional laparoscopic ureteral reimplantation with psoas hitch. METHODS: We retrospectively analyzed the data of 10 patients undergoing robotic-assisted laparoscopic ureteral reimplantation with psoas hitch and 6 undergoing conventional laparoscopic ureteral reimplantation between June, 2013 and December, 2014 in the General Hospital of PLA. The indications, surgical techniques and outcomes of the two procedures were compared. RESULTS: All the patients completed the laparoscopic procedures without conversion to open surgery. Robotic-assisted and conventional laparoscopic procedures were comparable in terms of the mean operation time (165.50=52.57 vs 152.50=73.60 min), mean volume of blood loss (81.00=69.35 vs 46.67=31.41 mL), mean duration of catheter retention (6.75=1.74 vs 7.50=2.43 days), and mean postoperative hospital stay (7.10=2.08 vs 8.67=3.14 days). The patients were followed up for a mean of 13.5 months, during which none of the patients experienced anastomotic leak, vesicoureteral reflux or hydronephrosis. CONCLUSION: There are no significant differences in surgical indications, surgical techniques or postoperative effect between robotic-assisted and conventional laparoscopic procedures of ureteral reimplantation with psoas hitch, but robotic-assisted laparoscopy can reduced the complexity in operation and increase the surgical precision in patients with a history of pelvic surgery, pelvic adhesion or secondary reimplantation.
