Abstract

Purpose: As a minimal invasive device for benign prostatic hyperplasia (BPH) treatment, prostatic urethral lift (PUL) is widely accepted worldwide but not widely used in Korea. We investigated the one-year results of for patients with BPH in Korea.
Materials and Methods: From April 2017 to June 2018, 42 patients with BPH were treated with PUL under local anesthesia with sedation. International Prostate Symptom Score (IPSS) and maximum urinary flow rate and post-void residual (PVR) were evaluated preoperatively and 1, 3, 6, and 12 months later.
Results: Mean age was 69.57±8.58 years old, and mean prostatic volume was 37.17±12.19 cc. Preoperative total IPSS and quality of life (QOL) were 19.94±7.81 and 3.69±1.30, respectively. Total IPSS improved to 11.26±7.22 (p<0.001), and QOL was 2.42±1.43 (p=0.01) after one month. Patients showed no evidence of inflammation related to the implants. IPSS and QOL were somewhat worse after 3 months but were better than baseline at 6 and 12 months. Preoperative maximum flow rate (Qmax) was 9.71±5.45 ml/sec, and one month after surgery, it had improved to 12.63±7.33 (p=0.01); it remained good at 3, 6, and 12 months (12.63±7.38, 12.45±7.39, 14.73±9.67). PVR was not significant at any points postoperative (80.61±67.91 to 43.95±8.19, p=0.119). No patient reported retrograde ejaculation, erectile dysfunction or urinary tract infection.
Conclusions: We evaluated the one-year efficacy of PUL for BPH treatment in Korea, and found significant improvement of IPSS, QOL and Qmax. It is expected that not only the improvement of voiding symptom but also the preservation of sexual function with a low risk of adverse events.
