Randomized comparison of transurethral electroresection and holmium: YAG laser vaporization for symptomatic benign prostatic hyperplasia.

OBJECTIVE: To evaluate the safety and efficacy of holmium:YAG laser vaporization v transurethral electroresection (TURP) for benign prostatic hyperplasia. PATIENTS AND METHODS: Thirty-six patients were randomized. Two laser procedures (60 to 80 W) were performed for one TURP. Symptom Score, peak flow rate, potency, and ejaculation status were measured at baseline and at 1, 3, 6, and 12 months. RESULTS: The mean operative time was 75 minutes for laser and 56 minutes for TURP (P = 0.0407). With a mean laser energy delivered of 103.6 kJ, hemostasis was satisfactory during vaporization. The mean catheterization time was 1.7 and 2.1 days in the laser and TURP group, respectively. For the laser and TURP groups, the mean AUA Score improved from 20 preoperatively to 7 and from 24.1 to 5, respectively, at 12 months. The mean peak flow increased from 8.4 to 19.5 mL/sec and from 7.6 to 16.8 ml/sec, respectively, at 12 months. These results are not statistically different. No significant initial dysuria occurred. No significant difference between the groups appeared in potency or ejaculatory status during the follow-up. One patient in the laser group (Day 5) and two in the TURP group (2nd and 6th month) had to undergo a second procedure to relieve obstruction. CONCLUSION: Although taking slightly longer to accomplish, holmium:YAG laser vaporization of BPH provides early results very similar to those of TURP with a shorter catheterization time and no initial dysuria or pain.[1]
