[Cysto-urethroscopy in the diagnosis of stress incontinence]

61 patients with a urinary stress incontinence of different degrees were examined by cysturethroscopy at a bladder volume of 300 ml in supine position and also by lateral urethrocystography in standing position. With increasing subjective stress incontinence, they showed an increasing dilation of the bladder neck in cysturethroscopy and lateral urethrocystography. At the same time the urethral closure pressure at the proximal urethra diminished. These observations offer new possibilities in the diagnosis of urinary stress incontinence.
