[Interpretation of the stress pressure profile in the diagnosis of female stress incontinence].

In 94 stress pressure profiles the electronically measured occlusion pressure under stress with a bladder filling of 100 ml in dorsosacral position and 300 ml in sitting position was compared with the computed value in the proximal and medial thirds of the urethra. Electronic measurement furnishes low, statistically confirmed occlusion pressure values. With a bladder filling of 300 ml in sitting position, urodynamic assessment of incontinence on the basis of the electronic occlusion pressure furnishes corresponding findings in over 70% of patients, while the extent of agreement with the computed values seems unsatisfactory. In stress pressure profiles, in accordance with clinical considerations and radiological studies, the proximal urethra should also be assessed as the first portion of the continence-preserving zones. The occlusion pressure, electronically measured under routine conditions, is the parameter which furnishes the most information for the urodynamic diagnosis of stress incontinence.
