传递到薄膜外,引起性神经的损伤,可以将术后性功能障碍的发病率降到2.3%。 TUBVP是双极切割,靠高聚焦的等离子体进行局限精确切割,术中使用生理盐水,对机体内环境干扰小;切割不是加热过程(切割面温度约40℃~70℃),热穿透浅(深层凝固坏死仅0.5~1mm),对勃起神经损伤小;由于前列腺包膜的阻抗与前列腺组织不一样,使前列腺组织很易被切除,而切到包膜时出现切不动的“打滑”现象,提醒手术者已到达包膜,可以避免切穿包膜损伤性神经;术中出血少,创面整洁,使尿道修复快。其性功能障碍的发生率较低,国外报道为2%[12]。我们的研究表明,TUBVP性功能障碍的发病率为5%,仍高于国外水平,可能与我们的病人就诊时年龄大,病程长及BPH引起的下尿路症状重有关。 本研究表明,前列腺手术对性功能和性激素的影响是存在的;手术损伤大,持续时间长,病人年龄大则术后性激素的变化大。前列腺不同的手术方式所引起的性激素水平变化,不是导致术后性功能障碍的直接因素;而手术方式则与术后性功能障碍直接相关。对机体损伤小,性神经影响小的TUBVP术后发生性功能障碍率最低,优于TURP和SPP。【参考文献】 1 Lue TF.Impotence after prostatectomy.Urol Clin North Am,1990,17:613-620. 2 朱积川.男子勃起功能障碍诊治指南.中国男科学杂志,2004,18(1):68-72. 3 吴阶平.吴阶平泌尿外科学.济南:山东科学技术出版社,2004,1130. 4 应俊,姚德鸿,蒋跃庆,等.前列腺增生症手术前后雄性激素变化的研究.中国男科学杂志,2002,16(3):233-235. 5 Kassabian VS.Sexual function in patients treated for benign prostatic hyperplasia.Lancet,2003,361(9351):60-62. 6 Uygur MC, Gur E, Arik AI, et al.Erectile dysfunction following treatments of benign prostatic hyperplasia:a prospective study.Andrologia,1998,30(1):5-10. 7 Deliveliotis C, Liakouras C, Delis A, et al.Prostate operations:long-term effects on sexual and urinary function and quality of life.Comparison with an age-matched control population.Urol Res,2004,32(4):283-289. 8 Aktan AO, Buyukgebiz O, Yegen C, et al.How minimally invasieve is laparoscopic cholecystectomy?
