Abstract

Objective: To assess the effectiveness of visual laser ablation treatmentwith holmium:yttrium-aluminum-garnet (Ho:YAG) laser in pediatricswith urethral strictures and to compare the results with those obtained inpatients treated with visual internal urethrotomy(VIU) urethrotomy.Materials and Methods: From January 2010 to January 2013, 32 malepatients aged 2 to 70 years (mean age 10.2) with primary urethralstrictures 0.5 to 1.5 cm long qualified for the study. 19 cases with thestricture length less than 1 cm and in 13 cases the length was more than1.0 cm .17 cases with the stricture in anterior urethra and 15 cases withthe stricture in posterior urethra The patients were treated using visuallaser ablation of urethral strictures (VLASU) with holmium:YAG laser.All the patients were investigated preoperatively by uroflowmetry andascending cystourethrogram with micturating urethrogrm and werefollowed up postoperatively with uroflowmetry and ascendingcystourethrogram at 3 months and 6 months. Urethrotomy was made atthe 12 o’clock position by retrograde vaporization of the scarred tissuethrough the total length of the stricture with the aid of a metal guidewire.Results: At 6-month follow-up, 21 cases (65.6%) did not requirerepetition of the procedure. The mean operation time was 30.8 minutes(range 20–45 minutes). The mean peak urinary flow rate (Qmax) was6.41± 1.78 l/s. the mean Qmax postoperative at 3 months was 17.26±5.9and at 6 months postoperative was 15.7±7.21Conclusion: VLASU can be used as a method of treatment of thisdisorder. It is an effective, modern, low-invasive, and repeatabletechnique and is technically simple and easy to master with resultscomparable to those of conventional urethrotomy.
