Microscopic Hematuria: New Recommendations

The American Urological Association has evolved from recommending a uniform standard (computed tomography and cystoscopy for everyone) to suggesting a risk-based approach to evaluation.

Sponsoring Organization: American Urological Association (AUA)

Background

A 2012 AUA guideline recommended that all patients older than 35 with microscopic hematuria undergo computed tomography (CT) urography plus cystoscopy. Now, the AUA presents a more nuanced approach, based on both new evidence and recognition that the previous approach subjected many low-risk patients to unnecessary testing.

Key Points

Microscopic hematuria still is defined as ≥3 red cells per high-power field (RBC/HPF) on urinalysis. A urine dipstick that is positive for blood, without ≥3 RBC/HPF, does not constitute microscopic hematuria.
Patients with microscopic hematuria should be divided into low-, intermediate-, and high-risk categories for genitourinary malignancy, …
