"Because many bladder neoplasms will not be detected by MDCT urography and more research is needed to determine the optimal technique for diagnosing bladder cancer, we think that MDCT urography cannot replace cystoscopy at present."

"MDCT urography now has a large role in the evaluation of patients with known and suspected bladder cancer. However, its precise role has not been established. Because many bladder neoplasms will not be detected by MDCT urography and more research is needed to determine the optimal technique for diagnosing bladder cancer, we think that MDCT urography cannot replace cystoscopy at present."

"3-dimensional images do provide another way of displaying the information and may be helpful in understanding complicated process (eg forniceal rupture), and anatomic relationships (eg congenital anomalies). 3-Dimensional images can also be used to help plan surgical and interventional radiology procedures."

- CT Urography: Indications per Society of Uroradiology
- Painless gross and microscopic hematuria
- Suspected transitional cell carcinoma
- Followup of transitional cell carcinoma
- Recurrent UTI’s
- Congenital anomalies
- Renal trauma "Most uroradiologists use CT Urography in their practice today; some no longer perform IV urography. Variability in multidetector-row CT technique suggests that more research is needed to determine the optimal protocol."

"CT Urography is essentially defined as a CT examination of the urinary tract before and after the administration of intravenous contrast material that includes excretory phase images."

"Most uroradiologists perform CT urography using multidetector-row CT aline (79%) and use a 3-phase technique (52%) using a single injection (76%) of contrast media at 3 ml/sec (52%) without a compression devise (81%) and with the patient in the supine position (90%)."

- "The addition of a saline bolus offers no improvement, whereas the addition of enhanced CT digital radiography offers significant improvement in collecting system opacification during CT urography."
