Ambulatory surgery for Moses™ holmium laser enucleation of the prostate A prospective, real-practice study from a single center.

Introduction: Use of ambulatory holmium laser enucleation of the prostate (HoLEP) is uncommon among Canadian urologists. Our objectives were to determine the feasibility (ambulatory success rate) and safety (early complication rate) of ambulatory HoLEP in a Canadian population.

Methods: We prospectively evaluated consecutive patients from June 2020 to May 2022 presenting for ambulatory HoLEP using Moses™ technology at our institution (MoLEP). Ambulatory success was defined as no hospital admission within 48 hours following the procedure. Thirty-day adverse events were also identified and graded according to the Clavien-Dindo (CD) classification. All procedures were planned to be ambulatory regardless of prostate size or anticoagulant treatment. We generated a logistic regression model to identify factors associated with ambulatory failure.

Results: A total of 61 patients underwent MoLEP, 52 of whom met the eligibility criteria. The mean age was 71.0 years (standard deviation 6.2). Most patients (67%, 35/52) were catheter or self-catheterization-dependent. The ambulatory success rate was 87% (45/52); 6/52 (11.5%) required hospitalization following MoLEP and one patient (2%) was re-admitted within 48 hours of the procedure. Hematuria was the sole cause of ambulatory failure. Thirty-day major complication rate (CD ≥3) was 6% (3/52) and the minor complication rate (CD <3) was 37% (19/52). The identified adverse events included hematuria (10/52), urinary retention (6/52), and cystitis (4/52). Based on univariate analysis, we did not identify factors significantly associated with ambulatory failure.

Conclusions: The MoLEP ambulatory success rate is high, and the 30-day major adverse event rate is low. In this small, Canadian cohort, ambulatory MoLEP seems feasible and safe.
