Abstract

<p>  From January 2006 to May 2017, a total of 1,500 patients underwent Photoselective Vaporization of the Prostate (PVP) at our hospital. We investigated long-term outcomes of these cases, especially re-treatments, to identify countermeasures for its prevention. Significant improvement of symptoms was maintained for over 10 years after PVP. However, we observed 33 cases (2.2%) requiring re-operation of the prostate. The 10-year re-treatment-free survival rate was 84.7%. In order to prevent reoperation, we consider it important to reduce residual adenoma as much as possible and avoid deep coagulation / the necrosis layer. PVP is a minimally invasive and safe surgery, and further improvement of curability will make it a more effective method.</p>
