Modified excretory urography in prehysterectomy patients

A retrospective (520 patients) and prospective study (100 patients) of prehysterectomy patients was done to determine the role of preoperative excretory urography. Potentially useful information was provided by the urogram in only a small number of patients (7.4%). It is arguable whether or not preoperative intravenous urography should be done in these patients. However, since most of these patients routinely undergo this study, we suggest that a curtailed urogram consisting of a KUB film, a postinjection 15-minute prone film, and a supine film of the contrast-filled urinary bladder is adequate for preoperative screening, thereby minimizing cost and radiation to the patient.
