title: Ultrasonography should replace intravenous urography in the pre-operative evaluation of prostatism.
abstract: In 48 patients referred for radiological evaluation as part of an investigation for benign prostatism both intravenous urography and ultrasonography were used. Ultrasonography combined with a plain abdominal radiograph was shown to be a better investigation than intravenous urography. Ultrasound was equally sensitive in detecting changes in the upper tracts and post-micturition residual volume and was more accurate in estimating prostate size. Intravenous urography was slightly more sensitive in detecting bladder wall changes, but this was not of clinical significance.
