ABSTRACT
The determination of the residual urine volume is an essential part of the investigation of many urological patients. particularly those with suspected urinary outflow obstruction. In 31 patients, we measured 3 internal bladder diameters ( height, width and depth) by transabdominal ultrasonography and calculated the residual urine volume by formula for ellipsoid (V= phi /6 xH xW xD).The real volume was obtained by the catheterization and compared with the sonographic measurement. There was a best correlation (r=0.9748) between calculated and true volumes provided a correction factor of 1.15 was applied. The advantages of ultrasonography for assessing residual urine volume are that it is simple, quick, harmless, non-invasive and readily repeatable. If the basic equipment is available, the ultrasonography should replace the catheterization.
