To observe the effect of "four-step"bladder neck-sparing plasma prostatectomy in the treatment of benign prostatic hyperplasia (BPH).

86 patients with BPH who underwent "four-step" bladder neck-sparing plasma prostatectomy in our hospital from January 2017 to October 2017 were enrolled in the observation group, and 83 patients with BPH who underwent transurethral bipolar plasma prostatectomy from March 2016 to December 2016 were enrolled in the control group. The operation time, gland resection time, postoperative irrigation time, indwelling catheter time and hospitalization time were compared between the two groups. All patients were followed up for 6 months. The residual urine volume (RUV), maximum urinary flow rate (Qmax), international prostate symptom score (IPSS) were used to evaluate the improvement of symptoms and urethral stricture. The incidence of complications such as urinary incontinence was compared.

The rate of gland excision in the observation group was higher than that in the control group[(74.63±10.92)% vs (60.08±12.49)% (P<0.05)]. The RUV and IPSS of the observation group and the control group after operation were (18.43±2.19) ml, (19.27±2.65) ml and (7.18±0.39), (7.56±0.42) respectively, which were significantly lower than those before operation (P<0.05). The Qmax of observation group 6 months after operation was (19.63±2.71) ml/s , which was significantly higher than that of preoperative (7.51±0.93) ml/s and control group (18.17±2.46) ml/s (P<0.05). The incidence of intraoperative complications and postoperative complications in the observation group were 2.33% and 24.42% respectively, which were lower than those in the control group (12.05% and 53.01%), (P<0.05).

Four-step bladder neck-sparing plasma prostatectomy is a safe and effective method for the treatment of benign prostatic hyperplasia.
