Electrovaporization of the prostate consists of the use of a high energy section current to destroy hyperplastic prostatic tissue. The authors present the preliminary results obtained with this new technique.
15 patients presenting indications for transurethral resection of the prostate were included in this prospective study. Three patients were in complete retention. Three patients presented a high operative risk (ASA 3). Electrovaporization of the prostatic tissue was performed according to the plans of resection using a round loop and a pure section current of 250 to 300 W.
The mean operating time was 22 min (+/- 13) for a mean prostatic weight of 43 g (+/- 7.7). No immediate postoperative haematuria was observed. The duration of catheterization was 2.2 days, and the mean hospital stay was 2.8 days (range: 2-4 days). With a minimum follow-up of 6 months, all patients were improved with an average flow rate of 22.17 +/- 8.6 mL/s, and a score less than 7. Two patients developed haematuria on D5 and D7, one patient developed resorption hyponatraemia and one patient died on D2 from acute respiratory failure.
EVP is an effective new resection technique designed to limit postoperative morbidity and the length of hospital stay, which uses inexpensive material. A randomized study versus loop resection should allow identification of the advantages of this technique.
前列腺电汽化术是利用高能切割电流来破坏增生的前列腺组织。作者介绍了这项新技术的初步结果。
15例有经尿道前列腺切除术指征的患者纳入了这项前瞻性研究。3例患者完全尿潴留。3例患者手术风险高(美国麻醉医师协会分级3级)。使用环形电极和250至300瓦的纯切割电流,按照切除计划对前列腺组织进行电汽化。
平均前列腺重量为43克(±7.7),平均手术时间为22分钟(±13)。术后未观察到即刻血尿。导尿时间为2.2天,平均住院时间为2.8天(范围:2 - 4天)。最少随访6个月,所有患者情况均有改善,平均尿流率为22.17±8.6毫升/秒,评分低于7分。2例患者在术后第5天和第7天出现血尿,1例患者发生吸收性低钠血症,1例患者在术后第2天死于急性呼吸衰竭。
前列腺电汽化术是一种有效的新切除技术,旨在限制术后发病率和缩短住院时间,且使用的材料成本低廉。与环形电极切除术进行随机对照研究应能明确该技术的优势。
