B超对神经原性膀胱合并尿道内括约肌松弛的诊断

B Ultrasound Diagnosis of Neurogenic Bladder Associated with Relaxation of Intraurethral Sphincter

应用实时Ｂ超仪探测了１１８例神经原性膀胱患者的尿道上段，并与Ｘ线膀胱造影及手术进行了对照。结果显示：实时Ｂ超能准确的反应尿道内括约肌张力情况，并能根据其肌松弛情况将其分为轻、中、重三度，从而使神经原性膀胱是否合并尿道内括约肌松弛于手术前即可确定诊断，进而术前确定手术方式，可避免部分病人不必要尿道损伤。

Real time B ultrasound was used to examine the upper urethral segments of 118 patients with neurogenic bladder. The findings were compared with those in cystogram and at operation. The results showed that B ultrasornd could evaluate the tension of intra urethral sphincter accurately and there by divided the degree of intraurethral relaxation, into mild, moderate and severe, as it was possible to diagnose unequivocally whether the neurogenic bladder of the patients were assocated with ralaxation ofo intra urethral sphincter and to determine the method of surggry before operation, thus avoid unnecessary damage to the urethra in a portion ofpatients.
