title: Intravesical residual urine of patients with benign prostate hyperplasia, sonography accuracy.
abstract: Measurement of intravesical residual urine is experimentally a diagnostic, therapeutic and follow-up criterion in patients with benign prostate hyperplasia. The study aims at evaluating sonography accuracy in measuring intravesical residual urine in comparison with standard and accurate way of measurement through bladder catheterization. The study was conducted on 60 patients hospitalized for benign prostate hyperplasia. Mean age of the patients was 67.10 +/- 8.33 years. In all patients with full bladder and after urination, the post void residue was initially measured by sonography at supine position and then immediately through bladder catheterization. This study evaluated 60 patients with mean age of 67.10 +/- 8.33 years. The difference between measuring through sonography and catheterization was 7.89 +/- 0.86, 14.46 +/- 1.87 and 32.73 +/- 2.99 mL in postvoid residue less than 50, 51-100 and more than 100 mL, respectively. In patients with benign prostate hyperplasia, transabdominal sonography is a non-invasive method to determine postvoid residue amount.
