YV-plasty in the treatment of patients with recurrent bladder neck stenosis

Abstract

Introduction. Bladder neck stenosis (BNS) is a late complication of surgical treatment for benign prostatic hyperplasia. Available methods of endoscopic correction in primary BNS have limited effectiveness, while in recurrent cases their use does not lead to satisfactory results at all. YV-plasty of the bladder neck (BN) is one of the available methods of treatment for recurrent BNS.Purpose of the study. To evaluate the treatment results of patients with recurrent BNS using endovideoscopic YV-plasty of the BN.Materials and methods. We retrospectively analyzed the treatment results of 8 patients with recurrent BNS who underwent endovideoscopic YV-plasty of the BN in the Urology Division No.1 of the St. Luke St. Petersburg Clinical Hospital from 2019 to 2021.Results. Endovideoscopic YV-plasty of the bladder neck was successfully performed in all 8 patients. The mean preoperative Qmax was 3.7 ml/s (1.8 – 5.7). At 6 months after surgery, the mean Qmax was 21.4 mL/s (16.7 – 24.1). The mean preoperative I-PSS score was 20.5 (17 – 24). The mean I-PSS score 6 months after surgery was 7.1 (5.0 – 9.0). No cases of de-novo stress urinary incontinence were registered.Conclusions. Endovideoscopic YV-plasty of the BN may be an effective and safe method of treatment of patients with recurrent BNS. However, further studies are needed to obtain long-term results.
