本篇研究係針對臨床上主訴有應力性尿失禁病人，於治療前給予尿流動力學的檢查。32位女性病人，年齡分佈由32歲至79歲，平均是53.6歲，接受尿流動力學檢查，包括尿流速，膀胱容積壓力以及應力緎尿道壓力檢查。在應力性道壓力檢查，有25位(78%)患者有負值尿道閉合壓力，但其中34%的患者同時合併有其化不正常的尿流動力學檢。其餘7位(22%)患者，呈現正值的尿道閉合壓力。其中有2位具不安定性的膀胱，1位有低的膀胱容積壓力適應力，另有1位患者有675毫升的殘尿，以上種種不定常的表現，可能是他們尿常禁的原因。所以由以上的結果分析，我們認為尿流動力學檢查，對於臨床上主訴有應力性尿失禁的婦人，在治療前有其診斷及評估的意義存在。

From October 1988 to December 1989, thirty-two female patients with subjective symptoms of involuntary urine loss during abdominal straining underwent urodynamic studies of lower urinary tract. The urodynamic evaluation included uroflowmetry, cystometry and stress urethral pressure profilometry (SUPP). Cystometry showed 88% (28/32) of the patients had stable bladder storage function, 6% (2/32) had detrusor instability and 6% (2 had low bladder compliance. The uroflowmetry showed low flow in 26% (6/32) and normal uroflow in 74% (17/32). Seventy-two percent (23/32) of the patients were found to have incomplete bladder emptying. SUPP revealed 78% (25/32) of the patients had negative urethral closure pressure during cough. The percentage of patients with abnormal urodynamic findings other than positive SUPP revealed 78% (25/32) of the patients had negative urethral closure pressure during cough. The percentage of patients with abnormal urodynamic findings other than positing cough. The percentage of patients with abnormal urodynamic findings other than positive SUPP only was 47. Thus it can be concluded that urodynamic studies are useful in making diagnosis and preoperative evaluation for patients with stress urinary incontinence.
