Patients presenting with prostate gland sizes greater than 200 cc pose a unique surgical challenge to both patients and surgeons. The objective of this study is to critically assess the efficacy and risks associated with performing holmium laser enucleation of the prostate (HoLEP) on glands ≥ 200 cc.
Using a prospective maintained database, all consecutive benign prostatic hyperplasia (BPH) patients with gland size ≥ 200 cc who underwent HoLEP were included. We reported patient preoperative, intraoperative, postoperative outcomes and complications. Subgroup analysis of outcomes was stratified by gland sizes 200-299 cc and ≥ 300 cc. Univariate analysis using Kruskal-Wallis and Fisher exact test was performed to compare the two groups.
There were 88 patients with a mean preoperative gland size of 255.9 cc (200-770 cc). Mean operative (171 vs 182 min) and enucleation time (77 vs 83 min) were not different between the two subgroups (200-299 cc vs ≥ 300 cc). Enucleation efficiency was greater for glands ≥ 300 cc (2.6 cc/min vs 2.0 cc/min, p = 0.04). Morcellation time was longer in the ≥ 300 cc group (74.5 min vs 46.8 min, p = 0.021). Mean length of stay was 1.8 ± 1.2 days and catheter duration was 2.6 ± 2.7 days. 1 (1.1%) patient required retreatment of BPH at last follow-up. The main limitation of this study is the retrospective data analysis.
Holmium laser enucleation for prostate glands volume > 200 cc is feasible with minimal morbidity. These data further reinforce the size independence success of this procedure for BPH.
