ABSTRACT
OBJECTIVE: To determine if MOSES technology improves efficiency and short-term outcomes in holmium laser ablation of the prostate (HoLAP). METHODS: A retrospective review of patients who underwent HoLAP between August 2016 and November 2019 was conducted. All procedures before and after the implementation of MOSES technology at our institution were evaluated. Preoperative patient characteristics and intraoperative data were collected. Postoperative International Prostate Symptom Score, quality of life, and postvoid residual measurements at 6 weeks and 3 months postoperatively were analyzed. RESULTS: This cohort included 65 males who underwent HoLAP, 32 without and 33 with MOSES. Patients in the MOSES group were slightly older, but no other differences in baseline characteristics were observed between the two groups. Ablation time was similar at 49.6 ± 26.1 minutes without and 40.7 ± 41.2 minutes with MOSES (P = .38). However, HoLAP with MOSES had significantly higher ablation efficiency (0.59 ± 0.24 g/min without vs 0.86 0.5 g/min with MOSES, P = .01). On multivariable regression modeling, HoLAP without MOSES added 12 minutes to operating time (estimate 12.3, standard error 3.44, P < .01) after controlling for prostate size and laser energy usage. Duration of catheterization, urinary incontinence and need for reoperation within 3 months were similar. There were no differences between groups in International Prostate Symptom Score, quality of life, or postvoid residual at 3 months postoperatively. CONCLUSION: Utilization of MOSES technology resulted in improved efficiency in HoLAP, translating into time savings in the operating room. Postoperative outcomes out to 3 months were similar among patients who underwent the procedure utilizing either laser pulse mode. Further studies are needed to investigate long-term outcomes as the use of MOSES is likely to become more commonly utilized.
