膀胱内压测量法是检查下泌尿道功能最广泛的方法,能直观见到膀胱内压力变化及漏尿倾向。检查结果可确定①真性应力性失禁:无逼尿肌不稳定者当膀胱内压超过最大尿道压力时不自觉漏尿。②逼尿肌不稳定:在充满期自发地存在或刺激逼尿肌收缩而病人正企图抑制排尿。但实际上逼尿肌不稳定症状(尿频、夜尿、尿急紧迫失禁和应力失禁)和对治疗的反应同试验结果不相关,例如有尿急症状的75人中36人膀胱内压测量为稳定膀胱,即试验
Bladder pressure measurement is the most widely used method of examining the lower urinary tract function, which can directly visualize changes in bladder pressure and leakage of urine. The test results can be determined ① true stress incontinence: no detrusor instability when the bladder pressure exceeds the maximum urethral pressure unconscious urine leakage. Detrusor instability: spontaneous presence or stimulation during detrusor contraction and the patient is trying to suppress urination. In fact, detrusor instability symptoms (frequent urination, nocturia, urinary incontinence and stress incontinence) and response to treatment are not related to the test results. For example, 36 of the 75 patients with urinary urgency had measurements of intravesical pressure Stabilize the bladder, that is, test
