Comparison of Newly Optimized Moses Technology vs Standard Holmium: YAG for Endoscopic Laser Enucleation of the Prostate

Abstract

Introduction: The purpose of this study was to describe our initial experience of using a newly optimized Moses technology that is part of the second-generation Moses platform specifically designed for holmium laser enucleation of the prostate (M2-HoLEP) and compare it with patients undergoing HoLEP using standard holmium:YAG technology (S-HoLEP).

Materials and Methods: We retrospectively collected data on patients who underwent M2-HoLEP and compared it with the last 50 patients in whom we performed S-HoLEP. Specifically, we compared preoperative symptom scores for lower urinary tract symptoms (LUTS) and erectile dysfunction (ED), preoperative objective voiding metrics, as well as intraoperative characteristics, perioperative characteristics, postoperative complications, postoperative symptom scores for LUTS and ED, and postoperative objective voiding metrics. Additionally, we evaluated the ability for same-day discharge following surgery in the M2-HoLEP group.

Results: We included 104 total patients for analysis. We compared the first 54 patients undergoing M2-HoLEP with 50 patients undergoing S-HoLEP. Both groups had similar age, body mass index, use of anticoagulation medication, LUTS and ED scores, and objective voiding metrics. Operations performed with M2-HoLEP had faster mean hemostasis time (8.7 vs 10.6 ± 6 minutes, p = 0.03) as well as hemostasis rate (0.13 vs 0.30 min/g, p = 0.01). Same-day discharge was achieved in 69.4% of patients in the M2-HoLEP group. Postoperatively, both groups also had similar and low rates of urinary retention and complications. At follow-up, both groups had similar symptom scores for LUTS and ED, as well as similar objective voiding metrics.

Conclusions: The newly optimized Moses pulse modulation technology is safe and efficient for the treatment of benign prostate hyperplasia. Such technologic improvements in the laser have greatly enhanced the feasibility of same-day discharge of patients undergoing HoLEP.
