Comparison of outcomes of holmium laser versus bipolar enucleation of prostates weighing >80 g with bladder outlet obstruction.

Transurethral enucleation of the prostate has been increasingly recognized as an effective minimally invasive technique for management of enlarged prostates. We aimed to compare holmium laser enucleation (HoLEP) and bipolar transurethral enucleation (B-TUEP) of large-volume prostates. A prospectively maintained database in two tertiary referral centers was reviewed for patients with HoLEP and B-TUEP for prostates >80 g. Operative data, perioperative complications, and early postoperative outcomes were compared. The study included 101 patients, 70 who underwent HoLEP and 31 who underwent B-TUEP. The operative enucleation rate (weight of adenoma enucleated in g/min) was higher in HoLEP compared to B-TUEP (P < 0.0001). The operative complication rate, hemoglobin drop, and readmission rate were comparable in both groups (P = 0.13, 0.35, 0.29, 0.59, respectively). The HoLEP arm had a shorter hospital stay and shorter catheterization time (P = 0.001, 0.012). Follow-up data showed a lower International Prostate Symptom Score and serum prostate-specific antigen level in the HoLEP group. The incontinence rate was comparable in both groups. In conclusion, both techniques were effective in managing a high-volume prostate, although HoLEP had a shorter enucleation time, better symptom score, lower postoperative prostate-specific antigen level, shorter catheterization time, and shorter hospital stay compared to B-TUEP.
