Sensation of filling can be defined as normal, increased (too strong, at small capacity), reduced (only one sensation—desire to void, or sensation only when the bladder is strongly filled), or as absent (as one of the signs of complete neurologic lesion).
Detrusor function during filling cystometry can be defined as normal with non-involuntary contraction during filling and no high pressure rise, as showing NDO or as detrusor areflexia.
Compliance is calculated (ml filling /cm H2O pressure rise) between two standard points, which need to be determined: i.e. first point at start of filling, and second point just before the last involuntary detrusor contraction, or at first leakage, or at cystometric capacity, or at desire to void. Calculating between start and the maximum measured contraction pressure does not represent bladder compliance, as indication of expendability and related to bladder filling.
