title: A catheter withdrawing apparatus for clinical urethral pressure profile studies.
abstract: An apparatus for withdrawing a urethral catheter at a constant speed is described. The motor and the puller assembly are separate components so that the puller assembly can be autoclaved. By matching pulling speed to recorder chart speed a reproducible representation of urethral length can be obtained without using a displacement transducer. The apparatus has been used clinically for measuring urethral pressure profiles.
