The flexed condition of the urethral and the posterourethrovesical angle can be clearly confirmed by the urethral locus indicating member, and the position of an exterior urethral opening member, and position of an exterior urethral opening can be surely grasped by the marking member which can be roentgenographed and which is positioned on the urethral locus indicating member and that it is prevented from penetrating into the uretra and this assists in examining of the external urethral opening during roentgenography of the urethral locus indicating member of the catheter.
