To compare and evaluate manually performed timed micturition in a domestic setting with registrations made using a home flowmeter.
Forty-six randomly selected men without voiding symptoms performed timed micturition at home both by hand and with a Da Capo home flowmeter. Statistical comparison using the Wilcoxon signed-rank test and regression analysis of the differences was performed to evaluate whether the two methods were comparable.
In two cases, there was a large discrepancy between the two methods. For the remaining 44 men, there were no statistically significant differences between the two methods. The median (range) timed micturition was 7 s (3-35 s) for manual measurements and 6.5 s (3.5-28 s) for electronic measurements. For each individual, the difference between the manually and electronically obtained medians was calculated. The average individual difference was 0.06 s (SD 1.6 s).
Approximately 95% of men are able to measure timed micturition at home manually without statistically or clinically significant differences from electronically obtained measurements. One has to be aware that in a small proportion of cases timed micturition measured at home may be falsely long.
比较并评估在家中手动进行的定时排尿与使用家用流量计进行记录的情况。
46名随机选取的无排尿症状的男性在家中分别通过手动和使用达科波家用流量计进行定时排尿。采用威尔科克森符号秩检验进行统计比较,并对差异进行回归分析,以评估这两种方法是否具有可比性。
在两例中,两种方法之间存在较大差异。对于其余44名男性,两种方法之间无统计学显著差异。手动测量的定时排尿中位数(范围)为7秒(3 - 35秒),电子测量为6.5秒(3.5 - 28秒)。计算了每个个体手动和电子获得的中位数之间的差异。个体平均差异为0.06秒(标准差1.6秒)。
大约95%的男性能够在家中手动测量定时排尿,与电子测量结果相比,在统计学或临床上无显著差异。必须注意的是,在一小部分情况下,在家中测量的定时排尿可能会错误地偏长。
