Study on 2 μm laser vaporesection of the prostate for the treatment of benign prostatic hyperplasia (BPH) with large volume

[Objective]To study the safety and the short-term effect of transurethral resection of the prostate 2 μm laser treatment of benign prostatic hyperplasia (BPH) with large volume.[Methods]25 cases of BPH (ranged from 80 to 100 g) were treated with 2 μm continuous wave laser vaporesection. Laser power was 70 W. Surgery in all patients before and after 3 months respectively international prostate symptom score (IPSS), maximum urinary flow rate (Qmax) and residual urine volume (RUV). Operative time, bleeding volume and electrolyte changes were recorded for patients in each group. The time after removal of catheter, bladder washing time and Length of Stay was observated.[Results]All patients were successfully completed surgery, postoperative obstruction of lower urinary tract symptoms was in varying degrees of ease. Preoperative and postoperative 3 months IPSS, Qmax and RUV had statistical difference (P 0.01). Operative time was (110±33) min, decreased hemoglobin levels was (10±7) g/L, and all without blood transfusion, meanwhile none of the patients with electrolyte disturbance, which resulted in the surgery was safe during peroperative period. The time after removal of catheter (3±0.9) d, bladder washing time (6 h) and Length of Stay (4±1.4) d was short after operation. There was no further surgery, urinary incontinence, and complications such as urethral stricture postsurgery. [Conclusion]2 μm continuous wave laser vaporesection is the treatment of BPH with large volume in an effective manner, and it can be significantly improved of symptoms of BPH patients with lower urinary tract obstruction.
