Abstract

Objective: To determine whether the recently introduced Lumenis Pulse 120H laser platform, which offers a dual-pedal footswitch and preset energy modes to easily switch among laser settings, facilitates a more efficient process in holmium laser enucleation of the prostate (HoLEP) for surgical treatment of benign prostatic hyperplasia. Patients and Methods: Patients at a single institution who underwent HoLEP with the new Lumenis Pulse 120H laser platform were matched 1:2 with patients who underwent the procedure with the previously used 100-watt VersaPulse single-pedal laser platform. Matching was performed by using propensity scores calculated by a logistic model that considered preoperative transrectal ultrasound prostate volume and patient age. The primary outcome was enucleation efficiency of each platform, determined by the weight of prostate tissue resected and enucleation time. The McNemar test and a conditional logistic model were used to associate predictors and cases. Results: Twenty-nine patients who underwent HoLEP with the Lumenis Pulse 120H platform were matched with 58 patients who underwent the procedure with the 100-watt platform. We observed statistically significant differences in operating room total time, procedure time, and enucleation time. Other perioperative and postoperative outcomes were comparable between the 2 groups. Enucleation efficiency was similar between the 2 laser platforms (0.89 g per minute in the control group vs 0.84 g per minute in the Lumenis Pulse 120H group). Conclusion: The efficiency of the new Lumenis Pulse 120H laser platform is comparable to the 100-watt VersaPulse laser platform in HoLEP when comparing g of tissue enucleated per minute.
