Objective:
To compare operative efficiency of Holmium laser enucleation of the prostate (HoLEP) using both the standard multi-incisional approach and en-bloc enucleation with early apical release during the initial learning curve.
Materials And Methods:
We retrospectively reviewed the initial 95 consecutive men who underwent HoLEP between April 2019 and September 2020 by a single surgeon. We compared patient demographics, and pre-, intra-, and post-operative metrics between both groups. Differences between groups were evaluated with Mann-Whitney U and Kruskal-Wallis tests.
Results:
Forty-nine patients underwent the standard HoLEP approach, and 46 patients underwent the en-bloc approach. Compared to a standard HoLEP, the en-bloc approach was associated with decreased operative time (131.11 minutes vs 153.59 minutes, P = .007) with similar weights of tissue removed. Operative efficiency, as measured by grams of prostate tissue removed per minute, was greater for the en-bloc approach (0.49 g/min vs 0.36 g/min, P = .005). There was no difference in length of stay (0.91 days vs 0.96 days, P = .383), laser efficiency (4.41 kJ/g vs 4.83 kJ/g, P = .200), or number of post-operative complications (10 vs 6, P = .236) between the groups.
Conclusion:
Utilization of the en-bloc technique during the initial learning curve allows for a faster, more efficient operation without any difference in functional outcomes or major complications compared to a standard HoLEP.
