Abstract
The catheter includes an inner tubular member and an outer sleeve member into which the inner tubular member is freely movably received. The inner tubular member has a section with calibrated markings. The calibrated section is spaced from the end adapted to be received in the urethra, by a distance equal to the length of the outer sleeve member. The outer sleeve member has an outwardly flared end adapted to be situated adjacent the external urethral meatus. The non-flared end of the sleeve member is used as a pointer against the calibrated markings to determine the length of the urethra.
