Most men with benign prostatic hyperplasia (BPH) have bothersome lower urinary tract symptoms (LUTS). This study aimed to investigate the safety and efficacy of high-performance system (HPS) laser photoselective vaporization of the prostate (PVP) for the treatment of BPH in men with detrusor underactivity (DU).


From March 2009, 371 patients with BPH were divided into 2 groups according to the findings of preoperative urodynamic study: 239 (64.4%) patients with bladder outlet obstruction (BOO) and 132 (35.6%) patients with bladder outlet obstruction with detrusor underactivity (BOO+DU). 120 W HPS laser PVP was performed to resolve the BOO. The perioperative data and postoperative results at 1 month and 12 months, including the International Prostate Symptom Score (IPSS), maximum urinary flow (Qmax), and postvoid residual urine (PVR) values, were evaluated.


Compared with the preoperative parameters, significant improvements in IPSS, Qmax, and PVR were observed in each group at 1 and 12 months after the operation. In addition, IPSS, Qmax, and PVR were not significantly different between the BOO and BOO+DU groups at 1 and 12 months after the operation.


Surgery to relieve BOO in the patients with BPH seems to be an appropriate treatment modality regardless of the existence of DU.
