Abstract

Background/aim: Transanal total mesorectal excision is a useful technique while performing lower rectal cancer and deep pelvic surgery. However, it is a relatively difficult procedure, and unique complications such as urethral injury have been reported. Although there have been a few reports on urethral visualization, we investigated whether it is possible to visualize the urethra using a fluorescent urethral catheter.

Patients and methods: We retrospectively examined the background and short-term surgical outcomes in 17 patients who, between April 2022 and December 2023, underwent transanal total mesorectal excision and transperineal total mesorectal excision with fluorescent ureteral catheters in place due to high risk of urethral injury.

Results: The urethra was recognized in one out of 11 patients (9.1%) in laparoscopic abdominoperineal resection and all three patients (100%) in laparoscopic total pelvic extenteration. No urethral injury was observed.

Conclusion: Visualization of the urethra by inserting a fluorescent ureteral catheter may prevent urethral injury in patients undergoing transanal/transperineal total mesorectal excision who are at high risk of urethral injury.

期刊介绍： ANTICANCER RESEARCH is an independent international peer-reviewed journal devoted to the rapid publication of high quality original articles and reviews on all aspects of experimental and clinical oncology. Prompt evaluation of all submitted articles in confidence and rapid publication within 1-2 months of acceptance are guaranteed. ANTICANCER RESEARCH was established in 1981 and is published monthly (bimonthly until the end of 2008). Each annual volume contains twelve issues and index. Each issue may be divided into three parts (A: Reviews, B: Experimental studies, and C: Clinical and Epidemiological studies). Special issues, presenting the proceedings of meetings or groups of papers on topics of significant progress, will also be included in each volume. There is no limitation to the number of pages per issue.
