We analyzed the perioperative parameters, postoperative urinary status, and complications of 200 patients who underwent photoselective vaporization of the prostate (PVP) with the 180W-X-ray photoelectron spectroscopy (XPS) for benign prostatic hyperplasia at our hospital. In addition, we compared perioperative parameters and complications, as well as the rate of decrease in prostate-specific antigen (PSA) and prostate volume at 3 and 12 months after surgery, with those of the last 200 patients who underwent PVP with the 120W-high-performance system (HPS). The results showed significant differences between methods in operative time (XPS: 67.9±29.0 minutes, HPS: 95.2±32.1 minutes, p＜0.05), laser exposure time (XPS: 41.4±17.8 minutes, HPS: 60.1±19.7 minutes, p＜0.05), and laser dose (XPS: 385,937±180,872, HPS: 300,316±105,528, p＜0.05). In addition, there were significant differences in the rates of decrease in PSA and prostate volume in the 180W-XPS group compared with the 120W-HPS group. The transpiration efficiency of the 180W-XPS was higher than that of the 120W-HPS.
