Catheters, Rectal, Manometric
Definition : Rectal catheters designed for measurement of pressure in the rectum and anal sphincter. These catheters may consist of tubes that require infusion of water at a constant rate, with ports through which flow rate is changed according to rectal or sphincter contractions (hydraulic manometry); these changes are converted into electrical signals by external sensors. Other catheters include several miniature built-in pressure transducers, avoiding the need of water perfusion. Manometric rectal catheters can evaluate the rectal musculature and anal sphincter functioning; they are mostly used in the diagnoses of fecal incontinence and constipation.
