Overview
Computed tomography(CT) of the kidneys and urinary tract is better than ultrasound in detecting stones in patients with hematuria, and it has the highest sensitivity, at 94% to 98%. Noncontrast helical CT is excellent for detection of urinary stones.
CT
CT urography has been increasingly supplanting intravenous urography when a urological cause for hematuria is suspected, as a result of its higher accuracy in detecting lesions in the renal parenchyma and the rest of the urinary tract.[1] CT urography involves the injection of iodinated contrast media, with subsequent high-resolution nephrogenic phase and delayed phase imaging to evaluate the renal pelvis, ureter, and bladder.[2]
Advantages
- Distinguish equivocal cases, for planning treatment options and determining the nature of small renal parenchymal lesions.[1]
- Has a high specificity and sensitivity for investigating the causes of hematuria.
Disadvantages
- CT is expensive, time consuming and carries a high radiation exposure.
