[Computer-assisted analysis of urethral pressure profiles in the woman]

The regular urethral stress profile which is applied for the diagnosis in urinary stress incontinence has been modified in two respects: Volley-like increasing pressure and a final spline-interpolation. With this method it is possible to analyze virtual standards for any variable of the profile. Measurements were carried out in 20 stress incontinent female patients compared with 10 healthy women. Urinary stress incontinence could not be verified through regular profiles (i.e. methods) in each of the 20 impaired patients. After the stress profile had been modified we proved that 11 Aases auf twenty definitely suffered from urethral insufficiency, 6 patients showed a deterioration of the profile and 3 had no change. It is possible to prove urinary stress incontinence by tracing the dynamics of the urethral pressure response which shows an irregular pattern in incontinent women.
