Coffee-colored discharge in urine

We all know that yellow urine may be caused by recent severe inflammation or a mild urinary tract infection. However, if the color of the urine is very dark and accompanied by coffee-colored phenomena, it may be caused by kidney inflammation or urethral disease. You can also observe the symptoms during urination. Generally, patients with inflammation will experience urethral pain and sore urination when urinating.

Normal fresh urine is light yellow in color because it contains a yellow pigment called urochrome.

However, the color of urine can also be dark or light depending on the amount of water you drink. If you drink more water and urinate more, the proportion of urochrome in the urine will be smaller, and the color will be lighter; if you drink less water, the proportion of urochrome in the urine will be larger, and the color will appear yellow. If urine is left for some time, its color will become darker. This is because some of the urochrome in the urine has been oxidized into urochrome. The waste produced by the human body and the urine pigments excreted every day are generally relatively constant, so the color of urine will not change much. 96%-99% of urine is water, and most of the rest is waste, such as uric acid, creatinine, etc. The normal daily urine volume of a person is 1000-2000 ml, among which men produce 1500-2000 ml per day. 1000-1500 ml for women. The urine is light yellow in color, transparent, and has no precipitation or turbidity. Fresh urine has a special grassy aroma, but after being left for a long time, it will produce ammonia due to decomposition.

Most abnormalities in the human body can cause changes in urine.

(1) Abnormal urine color

●Colorless urine may be a sign of diabetes, chronic interstitial nephritis, or diabetes insipidus. If it is not caused by drinking too much water, you should be careful to identify it.

●White urine White urine is common in purulent urine, chyluria and salt urine.

Purulent urine is caused by severe purulent urinary tract infection, and the urine is milky white. Purulent urine is common in pyelonephritis, cystitis, renal abscess, urethritis, or severe renal tuberculosis.

Chylous urine is one of the main symptoms of filariasis, and the urine is white like milk. Because the chyle (liquid after fat saponification) absorbed by the intestine cannot be drained into the blood circulation from the normal lymphatic vessels, it can only flow back into the lymphatic vessels of the urinary system, causing increased pressure in the lymphatic vessels in the urinary system, varicose veins and rupture, allowing the chyle to overflow into the urine, resulting in chyluria. Chylous urine is usually paroxysmal. When there are red blood cells in chyluria, it is called chylous hematuria. Microfilaria (i.e. young filaria) can sometimes be found in the blood and urine of patients with chylous hematuria.
