Toward efficient urography

A survey of intravenous urography in Nova Scotia shows a lack of consistency in timing and number of films used. Dehydration is still practiced in most centres and tomography is not used routinely. A revised protocol for urography is suggested, consisting of three films with additional views added as necessary. The three would include a single tomographic section when available. Dehydration procedures should be discontinued. Such a protocol might lead to a reduction in radiation exposure and patient risk and Canada-wide savings of more than three million dollars annually.
