Holmium laser enucleation of the prostate (HoLEP) is routinely performed with a 24F, 26F, or a 28F scope. Proponents of the larger scopes propose that a bigger sheath size allows for superior flow and visibility leading to a more efficient operation and better hemostasis. Those utilizing the smaller scopes suggest that the smaller sheath is less traumatic, resulting in lower stricture rates and temporary incontinence. We sought to compare outcomes of ambulatory HoLEP using the 24F and 28F laser scope. From May 2022 to March 2023, we randomized patients undergoing HoLEP (<200 cm in size) 1:1 to either a 24F or 28F scope. The primary outcome was differences in surgical duration between groups (minutes). Secondary outcomes included surgeon scope evaluation and postoperative patient results. There was no difference in patient characteristics in those randomized to 28F ( = 76) 24F ( = 76) ( > 0.05) scopes. Procedural duration and efficiencies were not different between groups (all > 0.05). The 28F scope was associated with improved surgeon-graded irrigation flow and visibility ( < 0.001). Patients treated with the 28F scope were more likely to achieve effective same-day trial of void (SDTOV) (28F 94.3% 24F 82.1%, = 0.048) and have a shorter length of stay (LOS) (28F 7.0 24F 11.9 hours, = 0.014), however, rates of same-day discharge (SDD) were not statistically different (28F 87.8% 24F 78.4%, = 0.126). There was no difference between the cohorts in rates of 90-day emergency room presentations, re-admissions, complications, or functional ouctomes ( > 0.05). We identified no clear advantage of scope size with regard to intraoperative or postoperative outcomes at 3-month follow-up due to scope size. However, if SDD is part of your postoperative pathway, the 28F scope may shorten LOS and increase rates of effective SDTOV. NCT05308017.
