当院における光選択的前立腺蒸散術 （PVP） の臨床的検討

Recently, photoselective vaporization of the prostate （PVP） has become an increasingly popular option for the treatment of lower urinary tract symptoms （LUTS） secondary to benign prostatic hyperplasia （BPH）, due to the associated lower morbidity. In the present study, we present the results of our experience with １２０-W high-performance system （HPS） laser PVP. From July ２０１２ to March ２０１５, a total of ６０ consecutive patients, with a mean age of ７０．０ years, underwent PVP. The mean prostate volume, the mean operative duration, and the mean hemoglobin decrease was ５８．８ cm３, ９３．５ minutes and ０．４ g/dl, respectively. Significant improvements were observed postoperatively in the International Prostate Symptom Score, quality of life score, maximal urinary flow rate, and postvoid residual urine volume. All of ７ patients with chronic urinary retention have become catheter-free. No major complication occurred intraoperatively or postoperatively. Although ７ patients （１１．７％） required recatheterization postoperatively, the catheters were able to be removed from all of them in a few days. The mean postoperative catheterization time including
recatheterization was ３４．１ hours. PVP with a １２０-W HPS laser is considered to be effective and safe for treatment of LUTS secondary to BPH.
