title: Holmium laser urethrotomy for urethral stricture.
abstract: A prospective cross-sectional study was carried-out in the department of urology, Dhaka Medical College Hospital (DMCH) to evaluate the outcome of Laser urethrotomy for the treatment of urethral stricture. For this purpose, 30 male patients aged 15 to 60 years with short segment anterior urethral stricture (>2cm) were treated by HO:YAG Laser. The energy used for this purpose was 0.8 to 1.5 joules by LISA 80 Watt Holmium Laser machine. All patients were catheterized for less than 24 hours and were followed up for 6 to 12 months postoperatively by uroflowmetry and by retrograde with voiding cystourethrogram 3 monthly. The study revealed that out of 30 patients, 27(90%) showed good flow of urine (Qave>16.0 ml/sec) and adequate caliber urethra in retrograde urethrogram (RGU). Only 3(10%) patients showed narrow stream of urine (Qave<8.0 ml/sec) and recurrent stricture in RGU which were managed by optical internal urethrotomy (OIU) and clean intermittent self catheterization (CISC). The study showed satisfactory results in 90% cases with short term follow up. The study concludes that HO:YAG Laser urethrotomy for the treatment of short segment urethral stricture is highly effective. The study further reveals that the method is simple, safe and thus, it can be considered favorably as a new therapeutic option for the treatment of urethral stricture. However, long term follow up is necessary for making a final comment on this issue.
