A method is described for the semiquantitative assessment of the strength of the detrusor contraction during any voiding for which the detrusor pressure, flow rate, and residual urine are measured. A computer is used to produce plots of detrusor pressure vs detrusor shortening velocity throughout voiding. The adequacy of the contraction can be followed through micturition until the bladder is nearly empty. In some cases the isovolumetric detrusor pressure and the maximum potential velocity of shortening of the detrusor can be estimated. The ranges of values found are comparable with those deduced from the stop test, although there are slight discrepancies. The median values of these two parameters form the basis of the routine method that can be used for any detrusor contraction.
