Experience of ۱۳۸ Transurethral Urethrotomy With Holmium:YAG Laser

Abstract Introduction: Many valid option modalities are available for the management of urethral stricture disease (USD), such as internal urethrotomy which has the success rates of ۳۳%–۶۰%. The aim of this study was to assess the outcome of holmium: YAG (Ho: YAG) laser urethrotomy (HLU).Methods: One hundred thirty-eight patients with urethral stricture with the mean age of ۴۸±۳.۰۳ years old treated by HLU from March ۲۰۱۱ to August ۲۰۱۷. The main purpose of this investigation was to evaluate mean operation time, stricture recurrence rate and post-operation Qmax and complications of transurethral HLU.Results: The most common cause of USD was trauma in ۸۲ (۵۹.۴%) patients. Mean laser operation time, mean hospital stay and mean postoperative duration of catheterization were ۲۳.۰۸ ± ۹.۱ minutes, ۱۹.۰۲ ± ۱۰.۷ hours and ۱۰.۳ ± ۱.۰۵ days respectively. The mean Qmax was ۸.۳ ± ۲.۰۷ mL/s before surgery and ۱۶ ±۳.۱ mL/s afterward. At the end of ۱۲ months follow-up, a total of ۳۷ (۲۶.۸%) patients developed recurrence of the stricture. Patients with posterior, longer urethral strictures and previous history of interventions have more recurrence rate of the stricture.Conclusion: HLU is minimally invasive and seems to be an effective and safe management option for primary, short, urethral strictures. The hospital stay is remarkably short and complications are negligible. Keywords: Urethral stricture Internal urethrotomy Holmium YAG laser Laser urethrotomy
