Figure 2: An example of a condom catheter measurement: The upper trace shows the pressure measured in the condom, the middle trace the urinary flow rate, and the bottom trace the voided volume. The numbered flags indicate the position of the valves in a binary code. 0 means all valves are open, outflow resistance is minimal. 7 means all valves are closed, effectively interrupting the urinary flow. Intermediate values offer intermediate resistance to flow.
