This study explored the use of ureteral catheter placement to prevent injury during laparoscopic gynaecologic surgery. Sixty patients who underwent laparoscopic surgery were randomly divided into test and control groups. The operative time, amount of intraoperative bleeding, time until return to routine activity, time until recovery of gastrointestinal function, length of hospital stay, need for postoperative analgesia, and incidence rate of ureteral injury were evaluated in the two groups. There were no ureteral injuries in the test group, but 1 patient in the control group had a ureteral injury (3.6%) (P<0.05). The operative time and amount of intraoperative bleeding were significantly different between the two groups (P<0.05), but there were no statistically significant differences in need for postoperative analgesia, time until return to routine activity, time until recovery of gastrointestinal function, and length of hospital stay (P>0.05). Pre-operative placement of a ureteral catheter can prevent injury during laparoscopic gynaecologic surgery, decrease the amount of intraoperative bleeding, and reduce the operative time. Preoperative ureteral catheter placement should be routinely performed in laparoscopic gynaecologic surgery, especially in patients with pelvic adhesions.
