Holmium laser enucleation versus transurethral resection of the prostate: 3-year follow-up results of a randomized clinical trial.

OBJECTIVES To report 3-yr follow-up results of a randomised clinical trial comparing holmium laser enucleation of the prostate (HoLEP) with transurethral resection of the prostate (TURP). METHODS A total of 200 patients with urodynamic obstruction and a prostate volume of less than 100 cc were prospectively randomised and assigned to HoLEP or TURP. All patients were assessed preoperatively and followed at 1, 6, 12, 18, 24, and 36 mo postoperatively. American Urological Association Symptom Score (AUA SS), maximum flow rate (Q(max)), and postvoid residual (PVR) [urine] volume were obtained at each follow-up. Perioperative data and postoperative outcome were compared. All complications were recorded. RESULTS AUA SS were significantly better 2 yr postoperatively in the HoLEP group (1.7 vs. 3.9, p<0.0001) and similar at 3 yr (2.7 vs. 3.3, p=0.17). PVR volume was significantly better 2 yr (5.6 vs. 19.9 ml, p<0.001) and 3 yr (8.4 vs. 20.2 ml, p=0.012) postoperatively in HoLEP patients. Q(max) was similar in the HoLEP and TURP groups at 2 yr (28.0 vs. 29.1 ml/s, p=0.83) and at 3 yr (29.0 vs. 27.5 ml/s, p=0.41) postoperatively. Late complications consisted of urethral strictures, bladder-neck contractures, and BPH recurrence; reoperation rates were 7.2% in the HoLEP and 6.6% in the TURP group (p=1.0). CONCLUSIONS After 2 and 3 yr of follow-up, HoLEP micturition outcomes compare favourably with TURP. Late complications are equally low. HoLEP may be a real alternative to TURP.
