OBJECTIVETo explore the recent clinical safety and efficacy of photoselective vaporization of prostate (120 W) for the treatment of large gland benign prostatic hyperplasia.

METHODSThe clinical data of 112 cases who accepted photoselective vaporization of prostate (120 W) for the treatment of severe benign prostatic hyperplasia (the weight of prostate > 75 g) from July 2010 to January 2012 was statistical analyzed. Relief symptoms and complications were observed around surgery, and the recent clinical efficacy was analyzed.

RESULTSAll the operations were smooth. There were not transurethral resection syndrome. No cases need transfusion intraoperative and postoperative. The operation average time was (52.6 ± 12.1) minutes, and the average amount of bleeding was (27.4 ± 18.5) ml. The postoperative bladder irrigating time was (19.4 ± 7.3) hours, the mean postoperative indwelling catheter time was (3.2 ± 0.6) days, and the mean postoperative hospital stay was (4.8 ± 1.3) days. Postoperative international prostate symptom score (t = 52.24 - 59.10), quality of life (t = 48.42 - 53.63), maximum flow rate (t = -31.01 - -24.23) and residual urine volume (t = 9.85 - 12.53) compared with preoperative are significantly improved (P < 0.01).

CONCLUSIONSWith the safe operation of photoselective vaporization of prostate (120 W) for the treatment of large gland benign prostatic hyperplasia, it is less bleeding, recent efficacy is significant, and it is especially appropriate to elderly patients at high risk of large gland.
