Combined Urethrocystometry and Cinefluorography in Continent and Incontinent Women

Abstract

Intravesical and intra-urethral pressures were recorded in 5 continent women and 10 women with urinary stress incontinence using combined urethrocystometry and cinefluorography. At rest, 2 types of stress incontinence could be recognized; 1 involved widening of the proximal urethra and the other did not. Under stress, the proximal urethra was rather mobile in the incontinent women. Artifacts caused by axial movement of the urethral microtransducer were eliminated by fixation of the catheter against the external meatus.
