To investigate the accuracy of uroflowmetry with disposable Q(Single) compared to measurements with a home-based digital device and compared to a single clinical measurement.
60 men with lower urinary tract symptoms were included in a prospective, open-label, multicenter study. Uroflowmetry measurements were done using three devices/methods: single clinic-based method, followed by up to 12 measurements using the disposable home-based Q(Single) and up to 12 measurements using a home-based digital device. Subjective data on ease of use of Q(Single) and preference of patients was investigated and objective measures of Q(max) and voided volume from the three devices were compared.
Mean Q(max) values of 12, 13 and 16 ml/s were achieved with the Q(Single) device, standard clinic method, and digital device, respectively. Mean Q(max) obtained with the Q(Single) device did not differ from that obtained with the clinic method. A significantly higher mean Q(max) was recorded for the digital device. Mean voided volumes recorded with each device differed marginally. Handling capabilities of the Q(Single) device were considered good by all subjects.
The accuracy of Q(max) and voided volume mean measurements with Q(Single) was comparable to one standard clinic recording. Q(Single) offers a viable alternative to reduce the number of clinic visits and can be used by other caregivers.
为了研究一次性使用的Q（单通道）尿流率测定仪与家用数字设备测量结果以及与单次临床测量结果相比的准确性。
60名有下尿路症状的男性被纳入一项前瞻性、开放标签、多中心研究。使用三种设备/方法进行尿流率测量：基于临床的单一方法，随后使用一次性家用Q（单通道）进行多达12次测量，以及使用家用数字设备进行多达12次测量。研究了关于Q（单通道）使用便利性和患者偏好的主观数据，并比较了三种设备的Q（最大值）和排尿量的客观测量值。
Q（单通道）设备、标准临床方法和数字设备的平均Q（最大值）分别为12、13和16毫升/秒。Q（单通道）设备获得的平均Q（最大值）与临床方法获得的平均Q（最大值）没有差异。数字设备记录的平均Q（最大值）显著更高。每种设备记录的平均排尿量略有差异。所有受试者都认为Q（单通道）设备的操作性能良好。
使用Q（单通道）测量Q（最大值）和平均排尿量的准确性与一次标准临床记录相当。Q（单通道）为减少门诊就诊次数提供了一种可行的替代方法，并且可供其他护理人员使用。
