Overview

ObjectivesTo report the safety and efficacy of holmium laser and compare its results with cold knife visual internal urethrotomy (VIU) in the management of short segment urethral stricture.MethodsThis prospective randomized study included 66 male patients aged more than 18 years, with short segment bulbar urethral strictures < 2 cm from March 2020 to March 2022. The patients were randomized into two groups each containing 33 patients. In group A (Cold knife group), Sachse cold knife was used for stricture treatment. In group B (Holmium group), internal urethrotomy was done with Ho:YAG laser. Patients were evaluated before the operation and followed up after the operation at 1, 3, 6 and 12 months by physical examination, IPSS, PVR, Qmax and retrograde urethrography.ResultsThere was significant improvement in the mean values of IPSS, PVR and Qmax in both groups. There was no significant difference between both groups in the mean values of IPSS, PVR and Qmax during follow-up visits. However, at the end of follow-up at one year there was statistically significant difference between both groups in the mean values of IPSS, PVR and Qmax due to higher recurrence rate in cold knife group than laser group. The overall complication rate is significantly lower in laser group (p = 0.014).ConclusionHolmium laser VIU is an effective and safe treatment option for short segment urethral stricture with shorter operative time, less complication rate and less recurrence than cold knife VIU.
