Evaluation of the adult with asymptomatic hematuria

BPH: benign prostatic hyperplasia; CT: computed tomography; HPF: high-power field; RBC: red blood cell; WBC: white blood cell.

* Abdominopelvic CT without contrast using a low radiation dose is recommended in most patients. For additional recommendations, refer to UpToDate topics on diagnosis of nephrolithiasis.

¶ Some patients with gross hematuria cannot empty their bladder due to severe clots and therefore develop urinary retention. Such patients should undergo prompt imaging and urology evaluation.

Δ Patients age <35 with noncontrast CT positive for nephrolithiasis may not need postcontrast imaging. For patients with contraindications to iodinated contrast, refer to UpToDate content for imaging options.
