Ureteral complications with operative gynecologic laparoscopy

Abstract

Objective: The study assessed the incidence, diagnosis, management, and causes of ureteral injuries during major laparoscopic operations at our department in a 6-year period.

Study design: The study was a chart review of 790 consecutive major laparoscopic procedures in 711 patients (mean age 37.4 +/- 11.6 years, mean weight 64.3 +/- 29.1 kg).

Results: There were four ureteral complications in three patients during or after laparoscopic operations: three of 711 patients (0.42%) and four of 790 procedures (0.38%). All three ureteral complications (one transection and a total of three ureterovaginal fistulas in two patients) occurred during laparoscopically assisted vaginal hysterectomies, for an incidence of 4.3%. There were no ureteral injuries in 291 salpingo-oophorectomies, 414 ovarian cystectomies, and 15 colposuspensions. Both delayed ureteral complications occurred in the lower segment of the ureter after laparoscopic bipolar coagulation and division of the cardinal ligament.

Conclusion: We conclude that in laparoscopic surgery the ureter is most at risk when the cardinal ligament is dissected and divided below the uterine vessels.
