The noncontrast-enhanced phase is optimal for detecting stones in the urinary tract; the nephrographic phase is useful for detecting renal masses, such as renal cell carcinoma; and the delayed phase outlines the collecting system of the urinary tract and can help detect urothelial malignancies of the upper urinary tract.9 Although the delayed phase can detect some bladder masses, it should not replace cystoscopy in the evaluation for bladder malignancy.9 After a negative microscopic hematuria workup, the patient should continue to be followed with yearly urinalysis until at least two consecutive normal results are obtained.5, In patients with microscopic hematuria, repeating urinalysis in six months or treating empirically with antibiotics could delay treatment of potentially curable diseases. Normal USG can range from 1.003 to 1.030; a value of less than 1.010 indicates relative hydration, and a value greater than 1.020 indicates relative dehydration. For the patient in case 1, because of his age, clinical history, and lack of other clear causes, the most appropriate course of action is to obtain blood urea nitrogen and creatinine levels, perform computed tomographic urography, and refer the patient for cystoscopy.5 An algorithm for diagnosis, evaluation, and follow-up of patients with asymptomatic microscopic hematuria is presented in Figure 1.5 The AUA does not recommend repeating urinalysis with microscopy before the workup, especially in patients who smoke, because tobacco use is a risk factor for urothelial cancer (Table 3).5, A previous article in American Family Physician reviewed the American College of Radiology's Appropriateness Criteria for radiologic evaluation of microscopic hematuria.8 Computed tomographic urography is the preferred imaging modality for the evaluation of patients with asymptomatic microscopic hematuria.5,8 It has three phases that can detect various causes of hematuria.
