Urine is cloudy
What is cloudy urine?
Cloudy urine is the urine with a turbid, cloudy-flocculent appearance, that means there is a large number of insoluble substances suspended in the urine. In healthy people, the fresh urine is clear and transparent; The urine color ranges from colorless, to a pale yellow to a bright yellow. If lots of cells, pus, mucus, bacteria, free fat globules or urate crystals are present in the urine, there is a cloudy urine. Sometimes, the normal urine can also be allowed a little cloudy; If you notice that your urine is occasionally a little cloudy, it does not mean you have health problems. Only a sustained, or very cloudy urine proves that you have urinary problems.
What does it mean when your urine is cloudy?
When you have cloudy urine, you are often worried and want to know: "why is my urine cloudy?". This has to be the most asked question urology physicians receive. That's because those suffering from the cloudy urine are in doubt that whether or not themselves are having some diseases from urinary tract, kidney, bladder, urethra, or even blood. Cloudy urine can be caused by a variety of causes, that may be harmless, disease, or even fatal. Fortunately, you don't have to worry about your urine is cloudy, if it is just an accidental cloudy urine, or you have always been healthy and there is no other symptoms or discomfort sensations when you pee: Occasional cloudy urine is usually harmless.
On the contrary, If your urine is persistently or repeatedly cloudy, hazy or milky for several days, it is usually an indication that you may have an urinary tract infection, but may also be other diseases. In addition, if your cloudy urine with odor (ammonia smell) or you have symptoms such as frequent urination, painful urination, burning sensation, They may be the strong evidence for the urinary tract infection (UTI). You'd better require medical attention to clarify the cloudy urine causes.
What causes cloudy urine?
Bacteriuria and pyuria are both the most common types of cloudy urine. They are both white, turbid, cloudy, or even with smelly odor. The bacteriuria means bacteria in urine, that always keeps typically cloudy even if left standing; The pyuria contains white blood cells or pus cells in urine, if left standing, there are flocculent sediments. Regardless of heating or adding acid to urine, the cloudiness will not disappear. They are both indicators of urinary tract infections.
Urinary tract infections (UTI) are the most common causes of cloudy urine, including kidney infection (pyelonephritis, renal tuberculosis), bladder infection (cystitis), urethritis. When you get a UTI, especially chronic urinary tract infection, you will have white cloudy urine, which contains lots of bacteria, white blood cells, pus cells, or secretions. For male patients with prostatitis, their prostate secretion fluid may be mixed in the urine. For adult women with vaginitis or cervicitis, they have their urine contaminated if the vaginal secretions mixed with urine. There are many factors that can promote urinary tract infections and ultimately lead to cloudy urine:
- If urine flow is blocked, you get UTI and cloudy urine; The obstruction factors includes kidney stones, bladder stones, renal pelvic tumor, bladder tumor, enlarged prostate, chronic prostatitis, congenital female urethral abnormalities, congenital ureteral stenosis, and neurogenic bladder.
- Chronic disease can reduce the body's resistance, thus urinary tract infections and the subsequent cloudy urine can occur. If you have a long-term diabetes, anemia, chronic liver disease, chronic kidney disease, malnutrition, congenital immunodeficiency, tumor, or long-term use of immunosuppressive therapy, the probability of getting urinary tract infections and cloudy urine is greatly increased.
- Pregnant women prone to urinary tract infection, therefore cloudy urine is very common; and the enlarged uterus often squeezes the ureter, to lead to a slow urine flow.
- Sometimes, urinary tract infections and cloudy urine occasionally may also be caused by operations, such as long-term indwelling catheter and fistula, urethral dilation, or prostate biopsy, cystoscopy due to improper operation.
If the cloudy urine causes are urethritis, vaginitis, or bacterial prostatitis, the patient's urine can contain mucus secretions, vaginal discharge or prostatic secretions; Especially vaginal discharge secretions, it often makes the cloudy urine foul smell.
An acute pyelonephritis, acute cystitis and kidney stones also often lead to red blood cells in urine; The urine is pink, not transparent, turbid. Strictly speaking, the "blood in urine" does not belong to "cloudy urine".
Crystalluria (crystals in urine) is also a type of cloudy urine, in which a lot of salts are precipitated from urine, such as uric acid, calcium oxalate, uric acid salts, bilirubin, amino acids, cholesterol, phosphate, sulfa drugs. The crystalluria color is varied, based on the composition of the crystalline substance, being white, red, yellow, brown, black. Cloudy urine caused by crystal deposition may be meaningless, harmless, normal, transient, or indicates the possible existence of some diseases, such as kidney stones, bladder stones, kidney disease, liver disease, infections, poisoning, etc.
