临床上泌尿生殖道脱垂和尿失禁者比正常妇女的盆底肌较薄弱,本文拟对上述三类妇女盆底耻尾肌用单纤维电肌图诊断盆底神经损伤。用逆行膀胱内压测量法诊断105例应力性尿失禁,左侧卧位用sims 窥器在休息或用力时前、后阴道壁或宫颈下降至阴道口诊断为生殖泌尿道脱垂。对照组69例。仰卧位用单针电极从20个不同针点记录的活动电位平均数和获得的肌纤维/神经纤维比率为运动单位纤维密度。单纤维电极经阴道固定在耻尾肌上,在直肠内置入一带气囊(充气50ml)的导管于盆底水平上,用150g 重力牵引诱发肌肉活动(阻留球管下移)记录单纤维肌电图。检查结果对照组未产妇41例的纤维密度随年
Clinically, genitourinary tract prolapse and urinary incontinence are weaker than pelvic floor muscles of normal women. In this paper, the pelvic floor muscle of the three types of women with single muscle electromyography to diagnose pelvic nerve injury. With retrograde measurement of bladder pressure 105 cases of stress incontinence, left lateral decubitus with sims resting or forced before and after the vaginal wall or cervix down to the vaginal opening diagnosed as genitourinary tract prolapse. The control group of 69 cases. Average activity potentials recorded from 20 different needle points in supine position with single needle electrodes and obtained muscle fiber / nerve fiber ratio were movement unit fiber density. Monofilament electrodes were fixed vaginally on shaggy tail muscle. A catheter with air bladder (50ml) was placed in the rectum at the level of the pelvic floor. Muscle activity was induced with 150g gravity traction Figure Inspection results in the control group 41 cases of non-maternal fiber density with years
