目的: To report the preliminary experience and results of the treatment of benign prostatic hyperplasia (BPH) by transurethral resection of the prostate with straight hair green laser ablation (PVRP).
 
 

方法: This study included 20 patients with BPH who underwent PVRP treatment of the bladder neck in the First Affiliated Hospital of Nanjing Medical University from September 2017 to March 2018. During the operation, the whole body was used to remove the prostate. The green laser energy was adjusted to remove (vaporization) 100W, hemostasis 40W, and a small transverse groove was cut from the 1cm level above the fine sputum. The depth reached the prostate surgical envelope level at the tip of the prostate. Cut into the sides, respectively, combined with the sheath sheath peeling, retrogradely cut the gland to the direction of 12 o'clock, do not enter the bladder, retain the bladder neck, completely remove the entire gland and push it into the bladder, switch to tissue The pulverizer attracts the excised prostate tissue block and pulverizes it and sucks it out. Clinical data were analyzed before and 6 months after surgery.
 
 

结果: All 20 patients were successfully treated with PVRP. The mean prostate volume was 75±26 ml; the mean total operative time and gland removal time were 74.8±21.9 and 44.5±15.4 min, respectively; the average resected prostate weight was 54.3±17.7 g. The estimated perioperative blood loss was 42.1±13.7 mL. , no blood transfusion. No prostate resection syndrome occurred in all patients. Compared with preoperative, the international prostate symptom score and urine residual volume were significantly reduced (23.1 ± 2.84 vs 12.5 ± 3.39, P < 0.001; 61.1 ± 30.8 vs 21.8 ± 8.8, P < 0.001), and the maximum urine flow was significantly increased （7.45±1.42 vs 20.63±1.42 ，P <0.001）.
 

结论: : 、、It is safe and effective to treat patients with BPH by monolithic method and PVRP with bladder neck preservation technique.
