Method for obtaining and displaying urethral pressure profiles
First Claim
1. A method for performing urodynamic testing on mammals, the method comprising the steps of:
- (a) inserting a pressure sensor to a first position within a urethra of the mammal, said pressure sensor adapted to transmit the pressure within the urethra to a data monitoring device;
(b) measuring the pressure within the urethra of the mammal while the mammal undergoes at least one stress maneuver;
(c) selecting one of said at least one stress maneuvers as an accepted stress maneuver;
(d) selecting a first urethral pressure measured prior to the accepted stress maneuver, a maximal urethral pressure measured during the accepted stress maneuver, and an intermediate pressure measured between the first urethral pressure and the maximal urethral pressure, said intermediate pressure occurring at a time interval from the start of said stress maneuver;
(e) moving the pressure sensor to a second position within the urethra;
(f) repeating steps (b), (c), and (d) at the second position; and
(g) displaying a timewise representation of urethral pressures at the first position and the second position during the pressure events on a display derived from the urethral pressures determined in step (d).

Abstract
A method for performing urodynamic testing on mammals. A pressure sensor, adapted to transmit the pressure within the urethra to a data monitoring device, is placed a first position within a urethra of the mammal. The urethral pressure is measured while the mammal undergoes at least one stress maneuver. A first, maximal and intermediate urethral pressure is measured during the stress maneuver. The pressure sensor is then moved to a second position within the urethra and the steps of performing the stress maneuver, selecting a stress maneuver and selecting the first, maximal and intermediate urethral pressures are performed at this second position. After completion of these steps a timewise representation of urethral pressures at the first position and the second position during the pressure events is displayed on a display derived from the first, maximal and intermediate urethral pressures.

26. A method for displaying urethral pressure profiles for mammals comprising the steps of:
-
(a) obtaining pressure measurements at a plurality of locations within the urethra of a mammal while the mammal undergoes a stress maneuver, said pressure measurements being plottable on a pressure-time graph as a stress profile;
(b) selecting a first pressure measurement obtained in step (a) from each location within the urethra used in step (a), said first pressure measurements selected such that they occur at substantially corresponding points in the respective stress profiles, said first pressure measurements forming a first set of profile pressures;
(c) selecting a second pressure measurement obtained in step (a) from each location within the urethra used in step (a), said second pressure measurements selected such that they occur at substantially corresponding points in the respective stress profiles, said second pressure measurements forming a second set of profile pressures;
(d) plotting each of said first pressure measurements on a first graph of pressure as a function of urethral location;
(e) plotting each of said second pressure measurements on a second graph of pressure as a function of urethral locations; and
(f) displaying each of said graphs in sequential manner. - View Dependent Claims (27, 28, 29, 30)
