Oxalate in urine is tested through a urine test. Calcium oxalate amount in urine can tell you the status of your kidneys and the deposited oxalates in the body. It can also give information about the chances of stones in the bladder or how much oxalates are passed in the urine. Oxalate is naturally produced during the metabolic procedures of the body. These are the by-products and are toxic to the body. If the oxalates or oxalic acid is not excreted out of the body properly it tends to deposit in the body in the form of crystals. These oxalic acids crystallise into hard stones and create problems inside the organs like kidneys, urinary tract, urinary bladder, gallstones. 

What is a calcium oxalate? And where is it deposited?

Oxalate is a common name of the chemical compound, oxalic acid. The oxalic acid produced in the body during various metabolic reactions including oxaloacetate cycle. The oxalate is mainly located extracellularly and in peroxisomes. Major body organs where it is generated or located are given below. 

Bladder

  1. 1. Kidney
  2. 2. Eye Lens
  3. 3. Intestine
  4. 4. Epidermis
  5. 5. Liver
  6. 6. Pancreas
  7. 7. Fibroblasts
  8. 8. Placenta
  9. 9. Testis
  10.  

Apart from generation of oxalic acid in the metabolic reactions other food sources also contribute in the development and deposition of calcium oxalate crystals in kidneys, urinary bladder, gallbladder, etc. Most common location where calcium oxalate is abundant is in the urinary tract.

Normal calcium oxalate levels in urine

On an average 50 mg of oxalate released in urine is considered normal, however, if there are chances of developing kidney stones or risks of recurrence of kidney stones or bladder stones then it might develop at 25 mg of oxalate excretion per day. Though this much amount of calcium oxalate comes under the normal category, stone formation can occur. 

Calcium oxalate in Urine Indicates 

High Calcium oxalate in urine indicates the condition of stone formed in kidneys. More than 50 mg of oxalate in urine indicates stones in urine or bladder. High amounts of oxalates that are not completely excreted out of the body can lead to toxicity as the oxalates deposit in kidneys and crystallise into kidney stones ultimately damaging the kidneys.  

Calcium Oxalate Stones Diagnosis and Treatment

If you or your doctor want to check your oxalate levels in the body or you want to confirm about the developing kidney stones or bladder stones your doctor will assign you some or all of the tests given below. Or you can personally ask for the tests to check if there are any stones developing in the body. 

Basic diagnostic tests include:

  1. 1. Urine tests
  2. 2. Blood tests
  3. 3. Diagnostic imaging tests like X-rays, ultrasound, CT scan
  4.  

Other examinations that checks for kidney stones or any sign of their accumulation include,

  1. 1. Kidney biopsy
  2. 2. DNA testing
  3. 3. Echocardiogram
  4. 4. Liver biopsy
  5. 5. Bone marrow biopsy
  6.

When the  patient is diagnosed with primary hyperoxaluria, it is a hierarchical condition and can be transmitted in children through genes.

Urine Tests

Urine is the last fluid prepared by kidneys after complete filtration. All the minerals that are filtered by the kidneys are released in the urine. In case of partial filtration or damage in kidneys’ functioning the toxic minerals find it difficult to excrete out and they deposit in other regions of the body including kidneys, urinary bladder, obstruct the urinary tract, etc. Urine can tell the doctor how much minerals are released through urine, and the amount of other metabolites are also checked through it. 

Blood Tests-

To check the functioning of kidneys and its filtered fluids, doctors ask for the blood test. This test also determines the oxalate levels in the blood. It helps in keeping a check over the amount of kidney stones passed out of the body or has dissolved or has been surgically removed. 

Diagnostic imaging tests like X-rays, ultrasound, CT scan

These imaging tests will help doctors to check for any abnormalities or depositions of minerals inside the kidneys, urinary bladder, etc.  

Other examinations that checks for kidney stones or any sign of their accumulation include,

  • 1. Kidney biopsy
  • 2. DNA testing
  • 3. Echocardiogram
  • 4. Liver biopsy
  • 5. Bone marrow biopsy

Calcium oxalate food to avoid

Calcium oxalate stones develop when the oxalate content in the body elevates to an abnormally high level and the kidneys find it difficult to excrete them out of the body. Other reasons include defected filtration processes that tend to retain the oxalates in the kidney itself and hence deposited minerals crystallise in stones. Hence, to avoid development or further deposition of calcium oxalate kidney stones you must follow a diet that is ore of calcium and lacks oxalates. 

Why to Opt for Calcium Rich Diet and Eliminate Oxalate 

Oxalate rich diet increases the amount of oxalate in the body and tends to enhance the oxalate deposition content in the kidneys that result in kidney stones. Calcium binds with oxalate in the stomach and intestine, much before it reaches the kidneys and prevents it from going towards and further deposition. Hence, calcium oxalate stone development can be ceased or prevented through a high calcium diet. 

How to Reduce Calcium Oxalate in Urine

Damaged kidneys defected filtration processes that tend to retain the oxalates in the kidney itself and hence deposited minerals crystallise in stones. Hence, to avoid development or further deposition of calcium oxalate kidney stones you must follow a diet that is ore of calcium and lacks oxalates. Calcium binds with oxalate in the stomach and intestine, much before it reaches the kidneys and prevents it from going towards and further deposition. Hence, calcium oxalate stone development can be ceased or prevented through a high calcium diet.
