A total of 20 men awaiting elective prostatectomy for bladder outflow obstruction underwent conventional medium filling cystometry and ambulatory monitoring of bladder pressures during natural bladder filling. Total bladder capacity was similar during both tests (medium filling cystometry 256 +/- 138 ml. and ambulatory monitoring 248 +/- 120 ml., p not significant) as was the voided volume (medium filling cystometry 180 +/- 100 ml. and ambulatory monitoring 179 +/- 88 ml., p not significant). However, the peak urinary flow rate at the end of medium filling cystometry (4 +/- 6 ml. per second) was significantly lower than during ambulatory monitoring (9 +/- 4 ml. per second, p less than 0.05). The bladder contraction pressure during medium filling cystometry (79 +/- 44 cm. water) was significantly lower than during ambulatory monitoring (107 +/- 39 cm. water, p less than 0.005). Bladder pressures during voiding recorded after natural filling were significantly greater than after artificial filling. This finding may have significant implications for the use of conventional cystometry to study conditions such as outflow obstruction.
共有20名因膀胱流出道梗阻等待择期前列腺切除术的男性患者，接受了传统的中等容量膀胱测压，并在膀胱自然充盈过程中对膀胱压力进行动态监测。在两项测试中，膀胱总容量相似（中等容量膀胱测压为256±138毫升，动态监测为248±120毫升，p值无统计学意义），排尿量也相似（中等容量膀胱测压为180±100毫升，动态监测为179±88毫升，p值无统计学意义）。然而，中等容量膀胱测压结束时的最大尿流率（每秒4±6毫升）显著低于动态监测时（每秒9±4毫升，p<0.05）。中等容量膀胱测压时的膀胱收缩压（79±44厘米水柱）显著低于动态监测时（107±39厘米水柱，p<0.005）。自然充盈后记录的排尿过程中的膀胱压力显著高于人工充盈后。这一发现可能对使用传统膀胱测压法研究诸如流出道梗阻等情况具有重要意义。
