[Transvaginal echocystourethrography].
The anatomo-physiologic appearances of female urination obtained with a new ultrasonographic technique is illustrated. The technique is performed using an intravisceral linear probe positioned in the vagina and a special chair which allows the urination in physiological position; at the same time the urination is videorecorded. The results, compared with X-Ray cystourethrography, enabled us to show the normal aspects (both dynamic and morphologic) and several pathologic aspects. Basing upon the direction of the urethra, it is possible to establish the change of the position of the floor and the neck bladder, which are often responsible of stress incontinence. The Authors stress the relative simplicity and noninvasiveness of the echographic technique. X-Ray radiation aren't used: this test is particularly advisable to study the urination disease of women in fertile-age.
