The practical value of ultrasonography as a rapid means to determine accurately residual urine volume was assessed.
Transverse and sagittal bladder diameters, as well as areas from longitudinal and transverse images, were measured with real-time ultrasonography in 324 men immediately after voiding. Calculated bladder volumes using measured diameters and areas for each of 11 formulas in the literature were compared to the corresponding measured total residual urine volumes.
The lower limit of ultrasonographic visualization of urine in the bladder was approximately 48 ml. No correlation existed between ultrasound calculated bladder volumes and measured residual urine for any of the 11 formulas.
Ultrasonography cannot rapidly measure bladder volumes accurately to date. Catheterization remains the most accurate method of assessing post-void residuals but in many cases it may not be the best approach to patient care.
评估超声检查作为一种快速准确测定残余尿量的方法的实用价值。
对324名男性排尿后立即进行实时超声检查，测量膀胱的横径和矢状径，以及纵向和横向图像的面积。将使用文献中11种公式通过测量直径和面积计算出的膀胱体积与相应测量的总残余尿量进行比较。
膀胱内尿液超声可视化的下限约为48毫升。11种公式中的任何一种，超声计算的膀胱体积与测量的残余尿量之间均无相关性。
迄今为止，超声检查无法快速准确地测量膀胱体积。导尿仍然是评估排尿后残余尿量最准确的方法，但在许多情况下，它可能不是患者护理的最佳方法。
