Abstract
A method for identifying and analyzing physiopathological parameters that characterize the condition of the lower urinary tract in patients in which computer generated theoretical urodynamic flow curves are generated, manipulated and compared with curves based on measured flow data for the patient. The method provides a means to determine the physiological condition of a patient without resort to, or with only minor, invasive techniques.
Claims10
A method for non-invasively identifying the functional status of the lower urinary tract comprising:
- recording urodynamic and pressure data of a patient during micturition,
- plotting said recorded data as curves,
- calculating theoretical models based on standard physiological parameters and plotting said models as curves,
- applying said theoretical model curves to said recorded data curves, and
- modifying values of said theoretical models to bring said theoretical model curves into coincidence with said recorded data curves,
- whereby physiological parameters affecting micturition are determined according to the values modified and the degree of modification necessary to achieve coincidence.
A method for non-invasive evaluation of the functional status of the human lower urinary tract comprising performing a direct comparison of recorded urodynamic data and theoretical models describing an ideal urinary tract using a computer and operating software to produce said theoretical models from supersonic flow calculations based on parameters consistent with characteristics for a healthy human urinary tract whereby the difference between said recorded data and said theoretical models is indicative of the functional status of said urinary tract.
