在12名健康受试者中进行了两种充盈率（50和100 ml min-1）的连续膀胱测压和逐步膀胱测压（连续快速容量输注，然后进行膀胱壁松弛）。耻骨上导管用于输注和记录膀胱周围和膀胱内压力。在充盈速率分别为50和100 ml min-1时获得的连续膀胱测压图在排尿欲望、跨壁压增加或膀胱容量方面没有差异。逐步膀胱测压允许膀胱充盈到比连续膀胱测压稍大的体积，但只有在膀胱扩张非常大时才具有相对较低的跨壁压。在连续和逐步膀胱测压中，跨壁压有相当大的个体差异。与常规临床膀胱测压相比，逐步膀胱测压似乎没有提供任何关于正常人膀胱压力-容积关系的重要额外信息。
Continuous cystometry at two filling rates (50 and 100 ml min-1) and stepwise cystometry (successive rapid volume infusions followed by bladder wall relaxation) were performed in 12 healthy subjects. Suprapubic catheters were used for infusion and recording of perivesical and intravesical pressures. The continuous cystometrograms obtained at filling rates of 50 and 100 ml min-1, respectively, did not differ with respect to desire to void, transmural pressure increase or bladder capacity. Stepwise cystometry allowed the bladders to be filled to a slightly larger volume than during continuous cystometry, but with comparatively lower transmural pressures only at very large distension of the bladder. There was considerable inter-individual variation in transmural pressure at both continuous and stepwise cystometry. Stepwise cystometry did not appear to provide any important additional information about pressure-volume relationship in the normal human bladder than could be obtained at routine clinical cystometry.
