bladder compliance
Measure of the bladder's ability to accommodate increasing volumes at low pressure during filling.
Full Definition
Bladder compliance is a urodynamic parameter that quantifies the bladder's capacity to store increasing volumes of urine while maintaining low intravesical pressure. It is calculated as the change in volume divided by the change in pressure (ΔV/ΔP) and expressed in mL/cmH2O. Normal compliance indicates a bladder that accommodates filling with minimal pressure rise, while poor compliance suggests a stiff bladder that generates high pressures during filling. In pediatric urology, poor compliance can lead to upper tract deterioration and requires intervention to protect kidney function.
Usage
Usage note: Always specify units (mL/cmH2O) when reporting numerical values.
