In investigation of hematuria the aim is as much to exclude serious illness as to establish the diagnosis. Hematuria which is demonstrated by a test strip should always be verified by examination of sediment. The further investigation comprises depiction of the kidneys with ultrasound examination together with cytological inspection of the urine and cystoscopy. The investigation is supplemented at need with computer tomography or angiography. Hematuria and simultaneous proteinuria or the incidence of pathological cylinders indicate parenchymatous kidney disease where the diagnosis is verified by renal biopsy. Hematuria in young individuals is usually due to infection, concrement or parenchymatous kidney disease. Already at age 40, however, cancer must be considered.
