The evolution of laser medical devices for benign prostatic hyperplasia (BPH) treatment aims to enhance vaporization, coagulation, or tissue removal. In this study, we aim to evaluate the effectiveness and safety of the innovative application of insulated-gate bipolar transistor (IGBT) xenon lamp-pulsed drive technology holmium laser in endoscopic prostate enucleation operations using canine models. Six canines were used as an experimental unit, the breed of the canine unit used was beagle. Each canine served as its own control to minimize the number of experimental units. Endoscopic enucleation, performed by a single surgeon, involved enucleating the left hemi-prostate, leaving the right hem-prostate untouched to serve as the control. Throughout the study period, all canines maintained good health. No adverse events were observed in all six canines. Postoperatively, there were no indications of redness, swelling, or other adverse effects at the surgical sites. No abnormalities were observed in the appearance and morphology of major organs. The prostate and bladder, removed for further pathological evaluation, exhibited no abnormalities in size, color, or texture. No abnormalities or inflammation were observed, and the tissues were free of adhesions, indicating successful healing. In conclusion, our comparison of preoperative and postoperative parameters in canines suggests that the IGBT pulsed laser, at a power setting of 100 W, demonstrates characteristics of safety, efficacy, minimal tissue damage, and no major postoperative complications. This study establishes a theoretical foundation for future applications in human settings, encouraging further exploration of the IGBT holmium laser's potential in clinical practice.

To explore the surgical effect and cost-effectiveness of day surgery versus inpatient surgery for photoselective vaporization of the prostate (PVP) in Chinese population. We retrospectively collected 240 patients undergoing day-surgery PVP (April 2016 to March 2018) and 156 patients undergoing inpatient-surgery PVP (May 2014 to March 2016). Differences between groups in demographics, perioperative outcomes, complications, and postoperative changes were calculated. Economical results in terms of hospital stay and relevant preoperative, intraoperative, and postoperative cost were evaluated. There was no significant difference in operative time, incidence of postoperative complications, and other functional outcomes between two groups (P > 0.05), but the waiting time for admission and the hospital cost including the drug charges, bed fee, nursing fee, laboratory test, and imaging fee of day-surgery group were significantly lower than that of inpatient-surgery group (P < 0.05). Day surgery of PVP has firm and well accepted position in ambulatory surgery of urology. It could significantly reduce the waiting time for admission and hospitalization costs in BPH patients.
