URODYNAMICS OF FEMALE URINARY-INCONTINENCE WITH EMPHASIS ON STRESS-INCONTINENCE

More than 500 female patients with urinary incontinence were studied by simultaneous recordings of urethral pressure at 2 levels, bladder pressure, intra-abdominal pressure, and by uroflowmetry and cine-fluoroscopy. Urethral pressure profile under basal conditions was compared to that in patients with a full bladder, under the stress of sharp or sustained increase in intra-abdominal pressure, voluntary perineal muscle activity and patient's position. From these studies stress and urge incontinence, and neurogenic varieties (or a combination of several types) could be differentiated. The clinical application of the findings is discussed.
