Abstract:
Objective To explore the feasibility and effectiveness of external ureteral clipping and insertion of double J tube in laparoscopic ureterobladder reimplantation. Methods The clinical data of 21 patients with lower ureteral stricture undergoing laparoscopic ureterobladder reimplantation from Mar. 2014 to Mar. 2016 were retrospectively analyzed. Twelve patients receiving conventional laparoscopic ureterobladder reimplantation were assigned to control group, and 9 patients receiving laparoscopy-assisted external ureterobladder reimplantation were assigned to improvement group. The ureter of the patients in the improvement group was separated under laparoscopy, the narrow ureter was severed, and the proximal ureter was taken out from the 12-mm Trocar. Then, the broken end of ureter was clipped under euthyphoria, and the double J tubes were inserted and fixed on the ureteral mucosa with 4-0 absorbable sutures and then sent back to the pelvis. The bladder was mobilized under laparoscopy, and the bladder and ureter were anastomosed. Results The surgery was successfully completed in all the 21 patients without transferring to open surgery or urine leakage after operation. The operation time was significantly shorter in the improvement group versus the control group ([77±17] min vs [104±20] min, P<0.05). All patients were followed up for at least 6 months after operation. Both ultrasonography and intravenous pyelography showed no ureteral anastomotic stricture. The hydronephrosis was alleviated to some extent. Cystography showed that 2 patients had reflux, with 1 case in each group. Conclusion In laparoscopic ureteral reimplantation, external ureteral clipping and insertion of double J tube are minimally invasive, and can shorten operation time and make the surgery less complex.
