Does urine that is the color of black tea mean blood in the urine?

When the color of urine is like black tea, the corresponding disease is medically called hematuria. There are many conditions and causes of hematuria. The occurrence of hematuria is often closely related to kidney lesions. When hematuria occurs, it should be taken seriously and it is best to go to the best nearby hospital for examination. In daily life, you should also quit smoking, drinking and spicy food.

Causes of hematuria

1. Urinary stones:

These include stones in the kidneys, ureters, bladder, or urethra.

2. Nephritis:

These include acute and chronic nephritis, focal nephritis, benign acute hemorrhagic nephritis, etc.

3. Urogenital Tumors

There are kidney tumors, ureter tumors, bladder tumors, prostate tumors, etc.

4. Urinary and reproductive system infections:

Such as prostatitis, urethritis, pyelonephritis, renal tuberculosis, cystitis, etc.

5. Other urinary system diseases:

Such as kidney ptosis, wandering kidney, congenital polycystic kidney, etc.

If hematuria occurs at the beginning of urination but the later urine is normal, it is usually caused by urethral disease. For example, if the beginning of urination is normal but hematuria occurs when urination is about to end, it is usually caused by cystitis and prostate disease. If hematuria occurs throughout the whole process and the blood is dark red, it is usually caused by kidney disease.

Common causes of red urine:

Red urine can be seen in many situations, such as hematuria, elevated bilirubin in urine, etc. It can be seen in liver disease and kidney disease, and further examination is needed to confirm the diagnosis. It is recommended to do a routine urine test first to see the cause of the redness. If it is elevated bilirubin, consider liver problems, and then further test liver function. If there is occult blood, consider kidney problems, and a color Doppler ultrasound of the kidneys, ureters, and bladder is needed.

Complications of hematuria

① If hematuria is accompanied by nose bleeding, bleeding gums, and skin bleeding, this may be due to a systemic bleeding disease, such as thrombocytopenia, allergic purpura, hemophilia, or even leukemia. Hematuria is just a manifestation of systemic bleeding.

②If hematuria is accompanied by fever, joint swelling and pain, skin lesions, and multiple organ damage, it may be a connective tissue disease (such as systemic lupus erythematosus, nodular arteritis, etc.).

③If hematuria is accompanied by hypertension, edema, and proteinuria, it is mostly glomerulonephritis.

④ If hematuria is accompanied by dull pain in the waist and abdomen, urgency, frequency, and pain when urinating, it is mostly urinary tract infection or tuberculosis.

⑤ If hematuria is accompanied by distension and pain in the lower back or abdominal cramps on one side, kidney or ureteral stones are most likely the cause. Especially if the patient is in so much pain that he cannot turn around in bed, it is most likely ureteral stones.

⑥ If hematuria is accompanied by difficulty, strain, and dripping of urine, in elderly men, it is mostly due to prostate hypertrophy, while in middle-aged men, urethral stenosis, urethral stones, or bladder tumors should be considered.
