Prostate Symptom Score (IPSS), a quality-of life (QoL) score, prostate-specific antigen (PSA) level, and prostate volume measured by transrectal ultrasonography (TRUS).
RESULTSThe mean ( SD , range) duration of PVP was 81.6 (22.9, 39-150) min, the mean energy used for PVP was 278 (60, 176-443) kJ and the mean duration of catheterization after PVP was 23.0 (17.1, 0-72) h. The mean ( SD ) maximum urinary flow rate improved from 8.0 (3.1) to 18.2 (8.1), 18.5 (9.2), 17.9 (7.8) and 19.3 (9.8) mL/s at 3, 6, 12 and 24 months, respectively. The IPSS and QoL scores showed similar improvements, and there was a statistically significant reduction in PSA level and prostate volume after PVP. There was no major complication and no patient had transurethral resection syndrome or a blood transfusion.
CONCLUSIONSThe 80 W KTP laser PVP offers rapid tissue ablation in patients with BOO caused by a large prostate. The short-and medium-term outcomes show that this technique can be a viable alternative to open prostatectomy.
