[Comparative determination of the vesico-urethral angle in incontinence via ultrasound and lateral urethro-cystogram (author's transl)].

Pre-operative diagnostic procedures in evaluating stress urinary incontinence in women became increasingly important within the last years. In many clinics the measurement of the posterior vesico-urethral angle using lateral urethro-cystograms has become an eminent criterion for the selection of the operative method applied. Until now, this angle could be measured by employing X-ray examination techniques. In this paper, an ultrasonic examination with the same accuracy as in X-ray. The technique of both methods and their advantages and disadvantages are discussed.
