Blood in Urine (Hematuria)

Sangre en la orina

Also: Hematuria (regional variant)

What it means

Blood in the urine is called hematuria. There are two types: gross hematuria, when you can see the blood in your urine, and microscopic hematuria, when you cannot see the blood but it can be seen under a microscope or is found with a urine test called a urinalysis. Gross hematuria makes urine look pink, red, or brown. Reasons for blood in the urine include infection or inflammation of the bladder, kidney, urethra, or prostate, urinary tract stones, and vigorous exercise; more serious reasons include cancer of the bladder, kidney, or prostate. Urine can also turn red from certain medicines, beets, or other foods. MedlinePlus says never to ignore blood you see in your urine and to get checked by a provider.

hematuriaGeneralMedical term: MedlinePlus en español says the presence of blood in the urine is called hematuria, and NIDDK heads its Spanish page "Hematuria (sangre en la orina)".
orina con sangreGeneralUsed in the running text of the MedlinePlus en español article where the English version says "bloody urine".

Sangre en la orina is a name MedlinePlus en español lists together with hematuria among the alternative names of its article, and NIDDK puts both in its page heading, Hematuria (sangre en la orina). Sangre and orina are feminine (la sangre, la orina), and so is the medical term: la hematuria. The MedlinePlus article also says orina con sangre where the English version says "bloody urine."

The two types are hematuria macroscópica (gross hematuria, when the blood can be seen) and hematuria microscópica. NIDDK describes the color of the urine as rosa, rojo o marrón. Related words on those pages: análisis de orina (urinalysis), coágulos de sangre (blood clots), vías urinarias (urinary tract), vejiga (bladder), riñones (kidneys) and cálculos or piedras (stones). "To urinate" is orinar, and the noun micción appears in micción frecuente (frequent urination).

Your right to an interpreter in the United States

If English is not your primary language and you have difficulty communicating in English, you may need an interpreter or a translated document when you visit a doctor or dentist, go to the emergency room or pick up a prescription. The U.S. Department of Health and Human Services Office for Civil Rights states that two federal laws, Title VI of the Civil Rights Act of 1964 and Section 1557 of the Affordable Care Act, require programs that receive its funding to provide language access services free of charge.

You can ask when you make the appointment or at the front desk: "I need an interpreter, please." «Necesito un intérprete, por favor.»
