Figure 1

Example of two bladder pressure volume (PV) curves. Curve A (black circles) shows the bladder PV curve in a patient with a normal bladder compliance: baseline intra-bladder pressure (IBP; at empty bladder) was 3 mmHg; bladder compliance was 38.3 ml/cm H2O (ΔV/ΔP1). Curve B (grey squares) shows the bladder PV curve in another patient with a low bladder compliance: baseline IBP (at empty bladder) was 10 mmHg; bladder compliance was 10.2 ml/cm H2O (ΔV/ΔP2). The PV curves are shown with the inflation/filling limb (right hand side) and the deflation/emptying limb (left hand side).
