Additionally, it is poor at detecting stone disease, which is a common etiology of microscopic hematuria. The appropriate upper tract imaging method should be determined by clinical circumstances, patient preferences, and available resources. A more limited or alternative evaluation may be sufficient in some low-risk patients, particularly those younger than 35 years without other risk factors in whom the risk of malignancy is low. A full workup should be completed after delivery and after persistent infection and gynecologic bleeding have been resolved.
Cystoscopy is recommended in all patients with asymptomatic microscopic hematuria who present with risk factors for malignancy, regardless of age Table 2.
In patients younger than 35 years, the probability of urinary tract malignancy is low; therefore, in the absence of risk factors, cystoscopy should be performed at the discretion of the urologist. If appropriate workup does not reveal nephrologic or urologic disease, then annual urinalysis should be performed for at least two years after initial referral. However, if asymptomatic microscopic hematuria persists on follow-up urinalysis, a full repeat evaluation should be considered within three to five years of the initial evaluation.

Hematuria may be visible with the naked eye gross hematuria or visible only under a microscope microscopic hematuria. The urine may look normal in patients who have have microscopic hematuria. Older patients and smokers have higher rates of hematuria. Smokers are also at an increased risk of genitourinary cancer. Hematuria can be caused by a number of different things, some of which are bladder or kidney stones; kidney disease; urinary tract infection, cystitis bladder infection , or pyelonephritis kidney infection ; cancers of the urinary tract kidney, bladder, prostate ; trauma, injury, or urinary tract instrumentation; rigorous exercise; benign prostatic hyperplasia enlarged prostate ; and blood thinners aspirin, warfarin, etc.
Hematuria can be confused with other urine discoloration caused by something other than blood in the urinary tract, such as foods like beets, bleeding from menstruation, blood from the gastrointestinal system, or medications. If you see blood in your urine, you should tell your primary care doctor. Otherwise, hematuria is usually detected during routine evaluation and without any other signs or symptoms. Sometimes, this happens with a dipstick urine test, which can have high false-positive result rates.
Therefore, all cases of hematuria must be confirmed in a laboratory by seeing 3 or more red blood cells in a sample under a microscope. Doctors generally use practice guidelines as an aid to evaluation. At this time, national guidelines recommend a complete evaluation in all patients aged 35 years or older who have hematuria without an obvious benign cause. Patients are typically referred to a urologist a surgeon of the urinary tract and sometimes a nephrologist a kidney specialist for this evaluation.
A timely and complete evaluation of hematuria is essential because a delay in diagnosis can be serious. Your treatment team should coordinate an evaluation of the entire urinary system. This will likely include urinary tract imaging and a cystoscopy to help determine the cause of the hematuria.
Imaging of the urinary tract usually consists of a computed tomography x-ray scan or an ultrasound.
