[Introital sonography--a new method in the diagnosis of bladder function].

In this study we introduce a non-invasive sonographic method called "introital sonography" which enables concomitant urodynamic measurements for evaluating the bladder function. During cystometry, urethral pressure profilometry and uroflowmetry, 20 patients with the symptom "loss of urine" and 10 healthy volunteers showed typical sonographic and urodynamic patterns, especially with regard to stress incontinence and urge incontinence. In contrast to video-urethrocystography, the lack of radiation exposure is advantageous. In contrast to perineal sonography, introital sonography allows simultaneous urodynamic measurements with applied catheters avoiding topographic and tonometric artifacts.
