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 the detection of urinary stones.
CT
CT urography may be helpful in the diagnosis of bladder cancer in a patient with gross hematuria without any obvious etiology. However, ultrasonography plus cystoscopy are usually enough, less costly, and safer as opposed to CT which includes the use of contrast material[1]. 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.[2] 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.[3]
Advantages
- Distinguish equivocal cases, for planning treatment options and determining the nature of small renal parenchymal lesions.[2]
- Has a high specificity and sensitivity for investigating the causes of hematuria.
Disadvantages
- CT is expensive, time-consuming, carries a high radiation exposure, and includes contrast material.[1]
