The RevoLix 2 micron continuous wave laser vaporesection for the treatment of high-risk patients with benign prostatic hyperplasia.

OBJECTIVE

To evaluate the safety and efficacy of the RevoLix 70W 2 micron continuous wave laser vaporesection in the treatment of high-risk patients with benign prostatic hyperplasia (BPH).

BACKGROUND DATA

Forty-six high-risk patients (mean age, 82.6 y old) with BPH underwent 2-μm continuous wave laser vaporesection.

MATERIALS AND METHODS

The operative time, drop in hemoglobin, drop in serum sodium, indwelling catheterization time, operative complications, international prostatic symptom scores (IPSS), quality of life (QoL), urinary flow rate (Qmax), and post voiding residual urine volume (PVR) were observed.

RESULTS

All 46 patients recovered without incident. The mean operative time was 68 ± 16.3 min. Occasional venous hemorrhage occurred during the operation, but no arterial hemorrhage was observed. Hemoglobin decreased from preoperative 15.0 g/dL to postoperative 14.3 g/dL, serum sodium decreased from preoperative 142.4 mmol/L to postoperative 141.6 mmol/L. IPSS decreased from preoperative 22 ± 6.2 to postoperative 9 ± 3.3, QoL scores decreased from 5.1 ± 0.7 to 2.1 ± 0.7, Qmax increased from 8.4 ± 5.2 to 21.2 ± 12.3 mL/sec, PVR decreased from 94.2 ± 60.2 to 21.6 ± 6.4 mL. The parameters were significantly different between pre- and postoperative results.

CONCLUSIONS

The RevoLix 70W 2-μm continuous wave laser vaporesection is safe and effective in the treatment of high-risk patients with BPH.
