title: Role of preoperative urography in benign prostatic hyperplasia.
abstract: The excretory urograms of 184 consecutive patients admitted to hospital with a diagnosis of benign prostatic hyperplasia who subsequently underwent prostatectomy were reviewed to determine the usefulness of preoperative urography. Of 184 urograms reviewed, 10 were normal, 136 showed changes consistent with benign prostatic hyperplasia, and 38 revealed other abnormalities. Twenty-seven of 184 urograms (14.7 per cent) revealed significant pathologic conditions requiring further consideration, investigation, or treatment, of which 23 would not have been suspected without this radiologic examination.
