Holmium: YAG Versus Cold Knife Internal Urethrotomy in Management of Short Urethral Strictures: A Randomized Controlled Trial
Holmium: YAG Versus Cold Knife Internal Urethrotomy in Management of Short Urethral Strictures: A Randomized Controlled Trial
Urethral stricture disease is defined as narrowing of the urethral lumen because of fibrosis, which occurs in urethral mucosa and surrounding tissues. The etiology could be congenital, iatrogenic, infectious, or idiopathic.
Several techniques are currently available for minimally invasive treatment of urethral strictures, including cold-knife incision, electrocautery, and various types of laser incisions. An incision with the cold knife does not cause any thermal effect on surrounding tissues but should create a mechanical injury that may lead to recurrence in long term. An incision with the electrocautery should cause a significant thermal effect on healthy surrounding tissues resulting in recurrent strictures during follow-up. Laser treatment modalities have gained popularity in the last two decades.
the aim of this trial is to evaluate the safety and efficacy of endo-urethrotomy with Holmium laser and cold knife endo-urethrotomy
Urethral stricture disease (USD) is the narrowing of the urethra from scar tissue, related to genitourinary tract infections, inflammatory skin conditions, traumatic urethral injury, pelvic radiation, and urinary tract instrumentation. It has an estimated prevalence rate of 0.6%.1-3 USD is a common and challenging problem for urologists. Multiple treatment modalities are available for the management of urethral strictures depending on the site and length of stricture, this includes simple urethral dilatation, urethral stenting, endoscopic visual internal urethrotomy (VIU), or open reconstruction.
Since 1974, Sachse's internal urethrotomy has been considered the treatment of choice for USD which is fast and simple to carry out and is associated with a short recovery time. The success rates are 33%-60%.
Bulow et al in 1979 introduced the laser for internal urethrotomy. The obvious dominance of Ho: YAG are clear vision, less bleeding, precise incision and ablation of scar tissue, and short hospital admission, however, most literature assessing the adequacy of the laser in contrast to cold-knife urethrotomy show no difference in final results.
The aim of this trial is to assess the efficacy, safety, complications, and results of Holmium laser urethrotomy and cold knife internal urethrotomy for urethral stricture.
