Ureteral complications with operative gynecologic laparoscopy

Area of Science:

• Urology
• Minimally Invasive Surgery
• Gynecologic Surgery

Background:

• Ureteral injuries are a potential complication of major laparoscopic operations.
• Understanding the incidence and causes of these injuries is crucial for patient safety.
• Laparoscopic procedures have become increasingly common in various surgical fields.

Purpose of the Study:

• To assess the incidence, diagnosis, management, and causes of ureteral injuries during major laparoscopic operations.
• To identify specific laparoscopic procedures associated with a higher risk of ureteral injury.
• To provide insights into preventing and managing ureteral complications in laparoscopic surgery.

Main Methods:

• A retrospective chart review of 790 consecutive major laparoscopic procedures involving 711 patients.
• Data collection focused on ureteral complications, including their timing, type, and association with specific surgical steps.
• Statistical analysis to determine the incidence rates of ureteral injuries.

Main Results:

• Four ureteral complications occurred in three patients (0.42% of patients, 0.38% of procedures).
• All ureteral complications, including one transection and three ureterovaginal fistulas, occurred during laparoscopically assisted vaginal hysterectomies (incidence of 4.3%).
• Delayed complications involved the lower ureter after laparoscopic bipolar coagulation and cardinal ligament division.

Conclusions:

• The ureter is most vulnerable during laparoscopic surgery when the cardinal ligament is dissected and divided below the uterine vessels.
• Laparoscopically assisted vaginal hysterectomy is associated with a significant risk of ureteral injury.
• Careful surgical technique, particularly during cardinal ligament dissection, is essential to minimize ureteral injury risk.
