Blood in urine (hematouria) has to be taken very seriously, especially if it is experienced WITHOUT pain. Several conditions can cause hematouria. Stones, infections and tumors of the urinary tract are the most common. Severe colic pain is typical in patients with stones. The pain is usually associated with frequent and painful urination and little blood in the urine. The most typical symptom of an urinary tract infection is disuria (painful urinating) and frequent urinating. Pain and hematouria appear during severe infections. In tumors, blood in the urine can be the first and the only early symptom. Tumors usually go without pain. If pain does manifest, it is usually a late symptom. Go immediately to an urologist. You need to do blood and urine analyses, an ultrasound examination, and endoscopyc cystoscopya if it is requested.
