经尿道等离子束前列腺切除治疗良性前列腺增生297例报告

目的:探讨经尿道等离子束双极电切治疗良性前列腺增生的安全性与有效性。　方法:采用经尿道等离 子束双极电切行前列腺切除(PKRP)297例。前列腺重量35～102g,平均52g。　结果:PKRP手术时间40～65 min,平均51min。切除前列腺组织重量34～80g,平均46g。无电切综合征发生。术后4～5d拔除留置导尿管, 全部病例排尿通畅。国际前列腺症状评分由术前31.5分降至术后6.8分(P<0.001)。最大尿流率术前平均6.3 ml/s升至术后18.6ml/s(P<0.001)。术前残余尿平均97ml,术后降至平均10ml。术后出现暂时性尿失禁4例, 继发性前列腺出血2例,尿道狭窄1例。　结论:经尿道等离子束双极电切术治疗良性前列腺增生安全有效。

Transurethral Prostatectomy with the Bipolar Plasmakinetic Technique for Benign Prostate Hyperplasia: a Report of 297 Cases

Objective: To evaluate the effect and safety of transurethral prostatectomy with the bipolar plasmakinetic technique (PKRP) in the treatment of benign prostate hyperplasia(BPH). Methods: Two hundred and ninty-seven BPH patients underwent transurethral prostatectomy with the bipolar plasmakinetic technique. The preoperative estimated weight of the prostate ranged from 35 g to 102 g, averaging 52 g. Results: The operation lasted 40~65 min, averaging 51 min. The resected tissues weighed 40~80 g, averaging 46 g. During the operation no transurethral resection (TUR) syndrome occurred. The catheter was removed 4~5 days after the operation, all with fluent urination. The patients were followed up for 2~33 months. IPSS decreased from average 31.5 preoperatively to average 6.8 postoperatively (P< 0.001). Average maximum flow-rate (Qmax) decreased from 6.3 ml/s preoperatively to 18.6 ml/s postoperatively (P< 0.001). Preoperative average residual urine was 97 ml and reduced to average 9 ml after the operation. Temporary incontinence occurred in 4 cases, perioperative hemorrhage in 2, and urethral stricture in 1. Conclusion: Transurethral prostatectomy with the bipolar plasmakinetic technique is a safe and effective means for the treatment of BPH.
