title: Comparison of a radionuclide method and catheterization for the measurement of residual volume of urine in the bladder.
abstract: Residual urine volume in the bladder was measured using a gamma camera and Tc-99m DTPA labeling of the urine and was compared to urethral catheterization in 21 male patients. The results of the radionuclide method did not differ significantly from the catheterization (P less than 0.001) and a good correlation was found between the two methods (r = 0.98). The results suggest that the simple, safe radionuclide method may be used instead of catheterization to measure residual urine volume in the bladder.
