Abstract
A system and method tests the gastric valve and urethral sphincter in a patient. A contrast agent is administered into the esophagus of a patient followed by inducing an involuntary reflex cough epoch within the patient to isolate the gastric valve from the lower esophageal sphincter (LES) and isolate the external urethral sphincter from the internal urethral sphincter. An imaging sensor detects the flow of the contrast agent during the involuntary reflex cough epoch and determines whether stomach reflux occurred indicative of a malfunctioning gastric valve. A determination is made if urine leakage occurs indicative of stress urinary incontinence (SUI).
