FIGURE 2. Pressure-flow studies and pressure-volume analyses.
(A) and (B) Representative cystometry measured pre- and post-operatively, respectively (PRE and POST). These cystometry show tracings of the detrusor pressure (Pdet), vesical pressure (Pves), abdominal pressure (Pabd), urethral flow (Flow), infused volume (Vinf), voided volume (Vvod), and intra-vesical volume (Vive). (C) and (D) Pressure-volume analyses established by plotting the Vive against Pdet. The regression line of the filling stage (red dashed line) is marked tilted counterclockwise after TVM that indicates an increased mean compliance (Cm). Moreover, before TVM, the trajectory displays a more infused than voided volume, indicating an amount of post-voided residual volume accumulated in the bladder.
