Photoselective sharp enucleation of the prostate with a front-firing 532-nm laser: an innovative surgical technique for benign prostatic hyperplasia-a single-center study of 475 cases.

PSEP is effective and safe for the treatment of benign prostatic hyperplasia. The innovative technique integrates the excellent hemostatic property of the 532-nm laser and the high efficiency of enucleation. It decreases the occurrence of postoperative incontinence associated with "blunt" enucleation of 532-nm laser and eliminates the lack of tissue samples problem associated with photoselective vaporization of the prostate.
