Ureteral illuminating catheters were used during gynecological laparoscopic surgeries, clearly visualizing the ureters and aiding dissection and bleeding control with one minor, transient complication.

This paper investigated the usefulness and safety of ureteral illuminating catheters during gynecological laparoscopic surgery, using two patients undergoing laparoscopic-assisted vaginal hysterectomy or laparoscopic hysterectomy. After laparoscope introduction, the catheters were reportedly clearly visualized within the ureters through the pelvic peritoneum, facilitating ureter dissection and control of periureteric bleeding. One patient experienced postoperative lumbar backache that resolved within one day, and no other complications were observed. The authors note that additional cases are needed to better assess safety. The paper’s discussion includes severe endometriosis as an example of technically challenging cases where ureter identification may be difficult, though the study is centrally about preventing ureteral damage during laparoscopic surgery.

Abstract

It has been reported that the incidence of ureteral injury during laparoscopic surgery is higher than during laparotomy. Accordingly, we investigated the usefulness and safety of ureteral illuminating catheters during gynecological surgery. Two patients underwent laparoscopic assisted vaginal hysterectomy and laparoscopic hysterectomy with the use of ureteral illuminating catheters. After introduction of the laparoscope, the catheters were clearly seen within the ureters through the pelvic peritoneum, facilitating dissection of the ureters and control of periureteric bleeding. Regarding the complications of ureteral illuminating catheters, lumbar backache was noted postoperatively in one patient, but it resolved after one day. No other complications were found. This method can be applied for training in laparoscopy at teaching hospitals, as well as in technically challenging cases where identification of the ureters is likely to be difficult, e.g. patients with severe pelvic adhesions, severe endometriosis, and malignant tumours. To assess the safety of ureteral illuminating catheters, we will investigate more cases in the future.
