The measurement of fluid energy loss during flow.
Urethral resistance is related to fluid energy degradation during flow. Hydrodynamic theory predicts that fluid energy loss can be estimated by measuring total fluid pressure during flow. In vitro experiments using a microtransducer catheter show the feasibility of this approach.
