Endoscopic Surgery of Urethral Strictures: Laser Versus Knife
Journal Title: The New Journal of Urology / Yeni Üroloji Dergisi - Year 2020, Vol 15, Issue 1
Abstract
Objective: We aimed to compare the efficiency of cold knife urethrotomy and laser urethrotomy in endoscopic surgery of urethral strictures. Material and Methods: A total of 171 patients were evaluated retrospectively. A 118 patients with complete data were divided into two groups (group 1; n = 53 cold knife urethrotomy, group 2; n = 65 laser urethrotomy) in the study. Length of the stricture, operation time, preoperative and postoperative 3rd, 6th and 12th-month Qmax values, recurrence and the presence of complications (such as bleeding, extravasation, fever etc.) were compared in terms of the two groups. Results: The operation time was found to be shorter in patients who underwent cold knife urethrotomy (14.01 ± 3.86 min vs 25.03 ± 4.43 min, p=0.001). The Q max values at the postoperative 3rd, 6th and 12th months were observed to be higher in patients who underwent laser urethrotomy (p=0.03, p=0.001, p=0.001). At the end of a one-year follow-up, recurrence was determined in 28 (52.83%) patients in group 1 and 12 (18.46%) patients had a recurrence in group 2 (p=0.01). No statistically significant difference was observed between the two groups in terms of postoperative complications. (p=0.209). Conclusion: In this study, it was determined that laser urethrotomy technique was a more successful surgical method than cold knife urethrotomy in the endoscopic surgery of urethral strictures as it has higher Qmax values and lower recurrence rate. The results should be supported by prospective, randomized studies.
