Sonographic assessment of postvoid residual urine volumes in patients with benign prostatic hyperplasia.

Abstract

With the above equation, we consider conventional transabdominal ultrasonography a reliable method for assessing the residual urine volume in patients with benign prostatic hyperplasia. This equation, though complex when compared to some of the pre-existing formulas, can be integrated into the memory of modern ultrasound machines for easy and faster computation.
