Fresh urine should be clear and transparent, without any special odor, and may have a small amount of foam, but it disappears quickly. Abnormalities in urine may indicate certain diseases.
1.Cloudy urine
Discharged urine is not clear and can be seen in urinary tract infections, filariasis, etc.
2.Urine odor
The odor of urine can be related to diet, especially after eating some stimulating foods such as onion and garlic, urine can have an abnormal odor, which should not be considered abnormal.
If the urine smells like ammonia, it can be seen in some diseases such as cystitis, urinary retention, etc. which are caused by holding urine for a long time, or poor urine discharge.
If urine has a foul odor, it is commonly seen in infected pus in some parts of the urinary system, such as pyelonephritis and cystitis; it is also seen in patients with vesicovaginal fistula.
If the urine smells like rotten apples, it may indicate diabetes.
3, foamy urine
People often think that a large amount of foam when urinating is an indication of good health, but this is actually incorrect. The foam is often caused by the presence of protein in the urine. Physiological proteinuria can occur under conditions such as strenuous exercise, fever, cold, mental stress, and sympathetic excitement. In addition to this, the appearance of foamy urine often indicates kidney disease, most commonly glomerulonephritis, tubulointerstitial nephritis, diabetic nephropathy, etc.
4.Hematuria
If there is 1 ml of blood in 1000 ml of urine, and the urine looks blood-like or washboard-like to the naked eye, this is called hematuria of the naked eye. During routine urine examination, if there are more than 5 red blood cells in a high-powered field of view under the microscope, or if the 12-hour urine Eddy count of red blood cells exceeds 1 million, and cannot be detected by the naked eye, this is called microscopic hematuria.
After finding hematuria, do not panic, first of all, you should distinguish whether it is true hematuria or pseudohematuria. Some medications can cause hematuria, such as aminopyrine, rifampin, and phenol red.
Other common causes of hematuria, include:
(1) Urinary system diseases: such as various kinds of nephritis, stones, congenital malformations, trauma, tumors, etc.
(2) Systemic diseases: such as bleeding disorders, leukemia, vitamin C and K deficiency, etc.
(3) Physicochemical factors: such as food allergy, radiation exposure, toxins, after strenuous exercise, etc.
To clarify which disease is causing the abnormal urine, we also need to conduct relevant examinations according to the symptoms and signs, so please seek medical advice promptly to avoid delaying the disease.

Hematuria
If there is 1 ml of blood in 1,000 ml of urine and the urine looks blood-like or washboard-like to the naked eye, this is called hematuria of the naked eye. During routine urine examination, if there are more than 5 red blood cells in one high magnification field under the microscope, or if the 12-hour urine Eddy count exceeds 1 million red blood cells and cannot be detected by the naked eye, this is called microscopic hematuria.
