Urethral and vaginal sensibility has been tested in 90 patients with urinary incontinence by means of urethral catheter and vaginal electrodes. Monophasic rectangular impulses with a frequency of 2 Hz, a duration of 2 msec and a variable intensity were used. The urethral sensibility threshold was 10.5 mA in patients with urge incontinence and 14.8 mA with stress incontinence. The vaginal sensibility threshold was by 20 mA higher and correlated well with the urethral one in its differentation of stress and urge incontinence. Because the big scattering of the values there was no statistical significance. Therefore this method is only valid to clarify patients complaints and to define impulse parameters for therapeutic intravaginal electric stimulation.
通过尿道导管和阴道电极对90例尿失禁患者进行了尿道和阴道敏感性测试。使用频率为2Hz、持续时间为2毫秒且强度可变的单相矩形脉冲。急迫性尿失禁患者的尿道敏感性阈值为10.5毫安，压力性尿失禁患者为14.8毫安。阴道敏感性阈值高20毫安，在区分压力性和急迫性尿失禁方面与尿道敏感性阈值相关性良好。由于数值离散度大，无统计学意义。因此，该方法仅适用于明确患者的主诉并确定阴道内治疗性电刺激的脉冲参数。
