[Transurethral resection of the prostate combined with 2-micron continuous-wave laser vaporesection for benign
Objective:
To sum up the clinical experience in the management of benign prostatic hyperplasia (BPH) with the prostate weighing over 80 ml by transurethral resection of the prostate (TURP) combined with 2 μm continuous-wave laser vaporesection (LVR).
Methods:
We retrospectively analyzed the clinical effects of TURP combined with 2 μm LVR in the treatment of 46 cases of BPH with the prostate volume > 80 ml.
Results:
All the operations were successfully accomplished. The operation time and intraoperative blood loss were (112.0 ± 20.0) min (range 86-176 min) and (77.9 ± 25.9) ml (range 50-200 ml), respectively. The catheters were withdrawn at 7 days after surgery. Transient urinary incontinence occurred in 6 cases and secondary hemorrhage was found in 2 postoperatively. Six-month follow-up revealed no urethral stricture or other complications. Compared with the baseline, the international prostate symptom score (IPSS) was significantly decreased at 6 months after operation (26.3 ± 1.8 vs 11.6 ± 1.7, P <0.05), and so were the quality of life (QOL) score (5.3 ± 0.7 vs 1.3 ± 1.1, P <0.05) and post-void residual urine (PVR) ([115.5 ± 55.6] ml vs [19.9 ± 11.6] ml, P <0.05). However, the maximum urinary flow rate (Qmax) was remarkably increased from (4.1 ± 2.6) ml/s to (16.2 ± 1.7) ml/s (P <0.05).
Conclusion:
TURP combined with 2 μm LVR is safe and effective for the treatment of BPH with the prostate volume >80 ml.
