A sphincterogram device used with radiographic equipment for measuring a patient's anal canal length, anal canal pressure, anorectal angle, and fatigability of the anal musculature. The sphincterogram device comprises an elongated expandable balloon having a flexible tubular catheter disposed substantially therein. The balloon is adapted for insertion into the patient's anal canal. The catheter has a plurality of openings spaced along a substantial portion of its length for communicating between the interior of the balloon and the interior of the catheter. The sphincterogram device also includes at least one fluid supply reservoir and at least one fluid flow line interconnecting the reservoir and the balloon for flow of fluid therebetween. The fluid supply reservoir is adapted for adjusting fluid pressure therein and for adjusting fluid pressure and volume in the catheter and balloon, and calibrations are provided for determining fluid pressure within the balloon. Additional aspects of this invention include a two reservoir system having two one way valves for exercising an anal sphincter; a method for measuring anal canal length, anal canal pressure, anorectal angle, and fatigability of the anal musculature; and a method for exercising the anal sphincter.
