经尿道双极等离子体前列腺电切术治疗良性前列腺增生症526例

Transurethral bipolar plasmakinetic resection of prostate for treatment of benign prostatic hyperplasia:a report of 526 cases

目的探讨应用经尿道等离子体双极电切术（TUPKRP）治疗良性前列腺增生（BPH）的有效性和安全性。方法总结应用TUPKRP治疗526例有梗阻症状的BPH患者的临床资料。结果切割时间17～130（50．2士31．7）min；切除前列腺组织重量12～150（26．3±23．2）g；术中出血量23～240（75．5±32．8）mL，无1例输血。7例发生包膜穿孔，无电切综合征发生。术后3个月最大尿流率（Qmax）由术前的（7．8±2．9）mL／s上升至（19．4±1．4）mL／s；剩余尿量（RU）由术前（90．8±30．7）mL下降至（16．5±12．0）mL；国际前列腺症状评分（IPSS）由术前（24．5±4．5）分下降至（4．7士3．4）分；生活质量评分（QOL）由术前（5．7士2．1）分下降至（1．5±0．4）分。结论TUPKRP治疗BPH具有安全有效、并发症少、费用相对较低等优点，值得推广。

Objective To assess the efficacy and safety of transurethral bipolar plasmakinetic resection of prostate（TUPKRP） for the treatment of benign prostatic hyperplasia（BPH）. Methods To summarize the data of 526 cases of benign prostatic hyperplasia（BPH） with obstructive symptom treated by TUPKRP. Results The duration of the procedure was 17- 13（50. 2±31. 7） min, and resected tissue weighed 12 - 150 （ 26.3 ±23.2 ） g ; the intraoperative blood loss was 23 - 240 （ 75.5± 32.8） mL and no blood transfusion was required. Seven cases had perforation of prostatic capsule, no transurethral resection syndrome occurred. The peak urinary flow rate（Qmax） increased from （7.8 ± 2.9） mL/s preoperatively to （ 19.4 ± 1.4） mL/s 3 months postoperatively. The residual urine（RU） decreased from（ 90.8 ± 30.7） mL preoperatively to（ 16.5± 12.0） mL. The international prostate symptom score （IPSS） decreased from（24.5±4.5） preoperatively to（4.7±3.4）. The scores of quality of life（QOL） decreased from（5.7±2.1） preoperatively to（1. 5 ± 0.4）. Conclusion Transurethral bipolar plasmakinetic resection of prostate for the treatment of benign prostatic hyperplasia is effective and safe with few complications and lower expense,and is worth promoting.
