Use of radioisotope renography and intravenous pyelography in carcinoma of the cervix

Radioisotope renography has proved uniquely useful in following patients with cervical cancer because of the ease of performance of the test, lack of need for special preparation, and ability to contribute information in many patients with azotemia. Serial renograms seem to give the most sensitive index to changes in renal function, particularly in patients who are under observation for recurrence of cancer after surgical or radiation therapy. In the patient with iodine hypersensitivity, the renographic technique may be the only procedure which will provide insight into the functional integrity of the urinary tract. However, when direct anatomic information is needed, intravenous or retrograde pyelography must be used.
