Aim: In this study, we aimed to compare the efficacy of Holmium YAG laser (Ho YAG) and cold knife incision in the literature. Material and Methods: Bladder neck stenosis was retrospectively screened in our hospital between January 2018 and January 2019. Recurrence time was defined as the maximum flow rate below 15 ml/s and/or when it became symptomatic. The patients were divided into two groups. The first group consisted of 14 patients with bladder neck stenosis who underwent cold knife procedure. The second group consisted of 17 patients with bladder neck stenosis who underwent Holmium laser. Results: In the group where laser ablation was applied due to bladder neck stenosis, the postoperative 6th month maximum flow rate was significantly higher (p =, 001), while post voiding residual (PVR) values were significantly lower (p = 0.029). When the groups were compared in terms of flow rate and PVR, there was no significant difference in terms of urine flow rate and PVR at 3 months, respectively. Nevertheless, the flow rate and PVR amount at 6 months were statistically significant in favor of the laser ablation group. Discussion: The use of holmium laser for bladder neck stenosis is promising in first-line treatment protocols with minimally invasive treatment modality, high success rates, low recurrence, and complication rates.
