本研究的目的是要探討受測者的各種特性是否會影響利用膀胱超音波掃瞄(Bladder Scan)來監測餘尿量的準確性，並評估膀胱超音波掃瞄與導尿兩者在時間及人力的消耗上之差異。本研究對象為住院及門診接受復健的71位病人，每位受測者在排尿後先以BladderScan BVI 3000掃描測量餘尿量，然後接著給予導尿。以重複測量變異數分析(Repeated-measure ANOVA)檢定，結果發現膀胱超音波及導尿所得餘尿量無統計上顯著差異，再以性別、診斷、姿勢、腹部脂肪厚度、膀胱形狀、尿量、操作間隔時間等因素做重複測量變異數分析檢定亦無統計上顯著差異。同時測量兩種花費護理時數：膀胱超音波掃瞄平均為45秒（17-119秒），導尿平均為293秒（136-664秒），膀胱超音波掃瞄與導尿所費護理時數相差3-8倍。本研究結果顯示，對於不同的對象，膀胱超音波掃瞄都可以掃描出正確的餘尿量，先以膀胱超音波掃瞄測量餘尿量可以減少不必要的導尿次數及節省醫療人力成本。

The aims of the present study were to investigate the impact of research subjects' characteristics on the accuracy of the BladderScan when the latter is used to measure post-void residual urine volume, and to evaluate differences between BladderScan and catheterization in terms of the expenditure of time and of human and material resources. Subjects in the present study were 71 patients undergoing inpatient or outpatient rehabilitation therapy. Post-void residual urine was measured with the BladderScan BVI 3000, followed by intermittent catheterization. Repeated-measures ANOVA revealed no statistically significant difference between the post-void residual urine volume measured by the bladder ultrasound and that of catheterization, or among the factors: sex, diagnosis, body position, thickness of abdominal fat, bladder shape, urine volume, and time intervals between operations. The BladderScan averaged 45 seconds (range =17-119 seconds), while catheterization averaged 293 seconds (range =136-664 seconds); the time required for catheterization was 3 to 8 times that for the BladderScan. The BladderScan gave accurate measurements of post-void residual urine volume for all of the subjects. Using the BladderScan first to measure post-void residual urine volume can reduce the frequency of catheterization, and can save medical human resources costs as well.
