Microscopic examination of the urine for evidence of hematuria or pyuria is a critical part of the evaluation of a patient with lower urinary tract symptoms and suspicious for acute urinary tract infections (UTIs). One retrospective study found that 67% of patients with ureterolithiasis had more than 5 red blood cells (RBCs) per high-power field (HPF), and 89% of patients had more than 0 RBCs/HPF on urine microscopic examination.[1] Chen et al. provided an interesting point of view that when presenting with acute UTI symptoms, patients with a high urine RBC median but lower urine WBC median are correlated with a higher probability of having urolithiasis disease. They found that the WBC median lower than 7.75 per HPF in urinalysis is a predictor for urolithiasis. While patients presented with UTI symptoms and lower urine WBC counts, a further image study, such as KUB or abdominal sonography, is required to identify other cause of UTI symptoms. However, in the present study, no further information about the correlation of lower urine WBC counts with the location or the size of urolithiasis. Further information on physical examination or detailed history taking is required to prevent computed tomographic scan and further high-dose radiation exposure.
