In 26 patients with detrusor-sphincter dyssynergia after a spinal cord injury the resting posterior urethra at cystography was found either closed as in normal subjects or open to a varying degree. Highest intravesical pressure measured at cystometry during uninhibited detrusor contraction was statistically significantly related to the degree of dilatation of the resting posterior urethra. An even higher correlation coefficient was found between the dilatation of the resting posterior urethra and an arbitrary score calculated on the basis of highest cystometric pressure and duration of disease since spinal cord injury. The possible importance of this finding in relation to incontinence after urethral sphincterotomy is discussed.
在26例脊髓损伤后出现逼尿肌-括约肌协同失调的患者中，膀胱造影时发现静息状态下后尿道要么像正常受试者一样闭合，要么有不同程度的开放。在无抑制性逼尿肌收缩时膀胱测压所测得的最高膀胱内压与静息状态下后尿道的扩张程度在统计学上有显著相关性。静息状态下后尿道的扩张程度与根据最高膀胱测压压力和脊髓损伤后疾病持续时间计算出的任意评分之间发现了更高的相关系数。本文讨论了这一发现与尿道括约肌切开术后尿失禁相关的可能重要性。
