The urethral compliance measuring device, consisting of a probe (1, 10) with a tube (2, 11) of diameter (D) containing at least one longitudinal canal (4, 5, 6, 12) and equipped with at least one means of pressure sensing each communicating with its respective canal, a means of fluid supply of the said canal and a means of pressure measurement of the said fluid characterized by the fact that the said means of pressure sensing is made up of an annular component (Z1, Z2, Z3, 15), the largest diameter of which (D1), in active pressure measurement position, is greater than the diameter of the said tube. In one form, the probe consists of at least two rigid, olive-shaped elements of different diameters, each pierced by an orifice communicating with an internal canal supplied with fluid, of which the pressure can be measured. In a second form, the probe consists of a balloon supplied with fluid and pressure-controlled.

Le dispositif de mesure de la compliance urétrale, comprenant une sonde (1,10) avec un tube (2,11) de diamètre (D) percé d'au moins un canal longitudinal (4,5,6,12) et pourvu d'au moins un moyen capteur de pression communiquant chacun avec son canal respectif, un moyen d'alimentation en fluide dudit canal et un moyen de mesure de pression dudit fluide caractérisé en ce que ledit moyen capteur de pression est constitué par un élément annulaire (Z1,Z2,Z3,15) dont le plus grand diamètre (D1), en position active de mesure de pression, est supérieur au diamètre dudit tube. Selon un mode de réalisation, la sonde comprend au moins deux éléments rigides en forme d'olive de diamètres différents et percés chacun d'un orifice communiquant avec un canal interne alimenté en fluide dont on peut mesurer la pression. Selon un second mode de réalisation, la sonde comprend un ballonnet alimenté en fluide et dont on contrôle la pression.
