ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the efficacy and safty of photoselective vaporization of prostate (PVP) in the treatment of benign prostatic hyperplasia with obstruction within 5 years.</p><p><b>METHODS</b>From December 2004 to December 2009, there were 782 cases have been except for neurogenic bladder dysfunction and prostate cancer, who received PVP surgical treatment of BPH. The surgical conditions and postoperative follow-up data were recorded and the follow-up cut-off time for surgery after 5 years.</p><p><b>RESULTS</b>A total of 782 patients with BPH who underwent PVP were included in this retrospective study. The operation in 740 cases was successfully completed at one time. But in other 42 cases, the twice operation was performed. The mean operation time was (85 ± 38) minutes, and the mean energy delivery was (355 ± 124) kJ. The mean catheterization and postoperative hospitalization time was (2.3 ± 1.7) days and (5.2 ± 2.6) days, respectively. No severe intraoperative complications were observed. The mean follow-up was (44.1 ± 19.3) months. The shortest follow-up was 6 months. The longest follow-up was 5 years. Complete follow-up data were available for 398 of the 782 patients. Of the 398 patients followed up for 5 years, the mean international prostate symptom score after 5 years was 12.8 ± 6.9, quality of life score was 2.2 ± 1.6, maximal flow rate was (14.5 ± 2.4) ml/s, and residual urine volume was 58 ml (M50). The retreatment rate because of BPH was 2.3% (9/398). Urethral stricture and bladder neck contracture were observed in 1.5% and 0.5% of the patients, respectively.</p><p><b>CONCLUSIONS</b>PVP has demonstrated remarkably consistent results for objective and subjective voiding parameters. Its late complication is rare and retreatment rate is low.</p>
