Urological Urine Examination

I have been experiencing chronic lower abdominal pain and lower back pain for over a year, along with frequent, unpredictable body aches, skin twitching, and a sensation of something crawling on my skin.
I first consulted a urologist who arranged for a urinalysis and bladder and kidney ultrasound to rule out any issues in that area.
I would like to know what items are typically checked in a urinalysis?

It is not possible to test all urine parameters; it still depends on the clinical need.
If there are any unclear points, feel free to ask again, and we can discuss and research further.
Online responses can only serve as a reference; if necessary, it is still important to seek medical care at a healthcare facility.

More Info

Urinalysis is a crucial diagnostic tool in evaluating urological health and can provide valuable insights into various medical conditions. Given your symptoms of chronic lower abdominal pain, back pain, and unusual skin sensations, it's wise to undergo a thorough urinalysis and imaging studies like ultrasound to rule out any underlying urological issues.

Key Components of Urinalysis
A standard urinalysis typically includes several key tests that assess different aspects of urine composition and can help identify potential health problems:
1. Physical Examination:
- Appearance: The urine should be clear; cloudiness may indicate the presence of bacteria, crystals, or other substances.

- Color: Normal urine color ranges from pale yellow to amber. Dark urine may suggest dehydration, while very light urine could indicate overhydration.

- Specific Gravity: This measures urine concentration. Normal values range from 1.003 to 1.035. Low specific gravity may indicate overhydration or kidney issues, while high values could suggest dehydration.

2. Chemical Analysis:
- pH Level: Normal urine pH ranges from 4.5 to 8. A high pH (alkaline) may indicate a urinary tract infection (UTI) or certain metabolic conditions, while a low pH (acidic) could suggest dehydration or a high-protein diet.

- Protein: The presence of protein (proteinuria) can indicate kidney damage or disease. Normal urine should have negligible protein.

- Glucose: Glucose in urine (glycosuria) can be a sign of diabetes or renal glycosuria.

- Ketones: Ketones in urine may indicate uncontrolled diabetes, fasting, or a low-carbohydrate diet.

- Bilirubin and Urobilinogen: These substances can indicate liver disease or hemolysis if present in abnormal amounts.

- Nitrites and Leukocyte Esterase: The presence of nitrites and white blood cells can suggest a urinary tract infection.

3. Microscopic Examination:
- Red Blood Cells (RBCs): The presence of RBCs (hematuria) can indicate various conditions, including infections, stones, or tumors.

- White Blood Cells (WBCs): Elevated WBCs can suggest infection or inflammation.

- Casts: These are cylindrical structures formed in the kidney tubules and can indicate kidney disease.

- Crystals: The presence of crystals can indicate kidney stones or metabolic disorders.

Importance of Urinalysis in Your Case
Given your symptoms, urinalysis can help identify potential causes of your discomfort. For instance, if your urinalysis shows signs of infection (like elevated WBCs or nitrites), it could explain your abdominal and back pain. If protein or blood is present, it may suggest kidney involvement, which warrants further investigation.

Next Steps
If your urinalysis results indicate abnormalities, your healthcare provider may recommend additional tests, such as:
- Imaging Studies: Ultrasound of the kidneys and bladder can help visualize any structural abnormalities, stones, or masses.

- Blood Tests: These can assess kidney function (e.g., serum creatinine, blood urea nitrogen) and check for diabetes or other metabolic conditions.

- Referral to a Specialist: Depending on the findings, you may be referred to a nephrologist or urologist for further evaluation and management.

In conclusion, urinalysis is a vital first step in diagnosing urological issues and can provide essential information about your overall health. Be sure to discuss your symptoms and test results with your healthcare provider to determine the best course of action for your situation.

It's good that the results are only (+-), which does not indicate any issues. It is recommended to wait for a period of time (not during menstruation) and then consult a urologist for a follow-up examination, as well as to perform an ultrasound check of the kidneys.
