The most recent advance in laser treatment of benign prostatic hyperplasia (BPH) is the introduction of a high-performance system (HPS) 120-W laser.
The HPS laser beam at a wavelength of 532~nm is highly absorbed by oxyhemoglobin in the tissue and maintains focus with negligible divergence up to 3 mm from the fiber and with limited divergence at 5 mm. This study is designed to evaluate the three-year clinical efficacy and safety of photoselective vaporization of the prostate (PVP, n=100 cases) with GreenLight HPS laser compared with transurethral resection of the prostate (TURP, n=100 cases) for treatment of BPH. The results showed that the mean operating time, catheterization time and admission time were significantly shorter in the PVP group, respectively. There were dramatic improvements in International Prostate Symptom Score (IPSS), quality of life (Qol), maximum flow rate (Qmax) and postvoid residual (PVR) compared with preoperative values and the degree of improvements was comparable in both groups. The intraoperative complications were lower in PVP group. In summary, PVP is an effective technique in patients with BPH, when compared to TURP, producing equivalent improvements in IPSS, Qmax, Qol and PVR with the advantages of markedly reduced catheterization time, admission time and adverse events.
