Abstract］ objective to assess the efficacy and safety of transurethral resection of prostatewith plasmakinetic technique and to improve the qualities of pkrp.methods the data of 273 patients with benign prostatic hyperplasiawere retrospectively studied baseing on the mastering of pkrp.the average maximum urinary flow rate,the average residual urinary volumeand the average international prostate symptom score were analysed.results pkrp was successfully performed on 273 patients.intraoperative blood transfusion was performed in 6 cases,no obturator nerve reflex,transurethral resection syndrome,permanent urinary incontinence occurred and no death cases occurred.the follow-up time was 2～26 months with an average of 5.63 months,postoperative average qmax increased to 15.9 ml/s,and ruv decreased to 16.0 ml/s and the average ipss was 9.compared with those of preoperation,the differences were significant.conclusion pkrp has superior tissue cutting function and hemostasis.it is suggested that transurethral bipolar plasmakinetic resection of prostate be effective and safe.

目的 探讨经尿道双极等离子前列腺切除术的安全性与有效性，提高pkrp质量。方法回顾性分析273例良性前列腺增生患者pkrp资料，比较手术前后最大尿流率、膀胱剩余尿量及国际前列腺症状评分。结果 273例手术均顺利完成，术中输血6例，无闭孔神经反射、永久性尿失禁、经尿道电切综合征及死亡病例，随访2～26个月，平均5.63个月，qmax平均增至15.9 ml/s，ruv平均降至16.0 ml，ipss平均9分。与术前相比，各项指标均有明显改善。结论 pkrp具有良好的组织切割功能及可靠的止血作用，治疗bph安全有效。

The results of silage test show that in each cutting of all treatments, the silaging result of half-hay+BM+PFJ is best, the next is half-hay ferment, result of fresh grass straight fermenting is worst. In each cutting the content of CP between half-hay+BM+PFJ and the raw material grass has tiny difference (respective discrepancy from others 0.18%, 0.60% and 0.94%).

各种处理中，半干+BM+PFJ 组与原料草粗蛋白差异最小，三茬半干+BM+PFJ 处理CP 含量和原料草分别相差0.18%，0.60%，0.94%，该处理青贮料NH3-N 最低，NDF 含量与原料草差异小，pH 最低，评定得分最高，说明半干+BM+PFJ 青贮效果最好，半干草添加PFJ 和BM 后能能促进乳酸发酵，能有效地改善苜蓿青贮的发酵品质，提高青贮饲料质量。

The reasons leading to them were given and the solutions were put forward. Through reducing the pouring velocity, the air gas entrapments and partial shrinkages can be elimiated effectively.
