Cystinuria is a condition that is caused by the accumulation of cysteine, an amino acid that is produced in the kidneys, bladder, and ureters. It is a rare and inherited disease passed to the children when both the parents have the condition.
Kidneys are important for the proper functioning of the body. It does the important function of flushing out toxins from the body through urine, maintaining your body’s overall fluid balance, and releasing hormones that help in bone health and regulating blood pressure.
In individuals with the condition, cysteine gets accumulated in the kidneys, bladder, and ureters. It is a painful condition and appropriate treatment is important. If you have small stones, medications can help them pass through urination. But if you have large stones, a surgical procedure is needed.
Cystinuria is a condition that can occur in individuals of all age groups.
But the symptoms of the condition are mostly seen in individuals between 10 and 30 years of age. Common symptoms of the condition include:
The cause of cystinuria is the defect in SLC3A1 and SLC7A9. These two genes are responsible to provide instructions to your body to produce certain protein complexes present in the kidneys.
These proteins are responsible for regulating the reabsorption of certain amino acids. Defects in even one of the genes can influence the ability of the protein complex to reabsorb amino acids. This further leads to the accumulation of amino acids in the kidneys and the formation of cystine stones.
You are likely to get the condition only if both your parents have a defect in SLC3A1 or SLC7A9 genes.
If you have any symptoms associated with cystinuria, consult your doctor. Your doctor will ask you about your symptoms, frequency of the symptoms, and family history of the condition.
Doctors diagnose cystinuria with the help of the following medical tests:
In most cases, the diagnosis of the condition is done when an individual has kidney stones. The kidney stones are tested to understand if they are cystine stones.
It is important to treat the condition as soon as it is diagnosed. The condition if left untreated can cause severe complications. Some of the complications caused by the condition include infection in the kidneys, damage of kidneys or bladder due to cystine stones, urinary tract infections and, blockage of the ureters.
The main aim of the treatment is to relieve symptoms and prevent the damage as well as the formation of more stones.
Treatment options include:
Increase your fluid intake – The first suggestion your doctor would give you is to increase your fluid intake. Your doctor will help you with the right amount of fluid you need to intake in a day. In some cases, your doctor may even recommend increasing the intake of fluid with the help of IV.
Medications – Your doctor may prescribe you medications that will help the cystine stones to dissolve with the urine. Make sure you take the medications as prescribed by your doctor and only for the recommended period. The medications may cause certain side effects. If you experience any unusual changes after consumption of the medications, make sure you inform your doctor about it.
Your doctor may even prescribe medications to relieve pain.
Surgery – Your doctor may recommend surgical procedures when medications and lifestyle measures are not effective. Surgical procedures are also recommended when you have severe pain or the cystine stones are large.
If both your parents have the condition, you are more likely to get the disease. Even though it is difficult to prevent, you may take the help of certain lifestyle measures and make the condition less painful and prevent further damage.
Some of the lifestyle measures you may consider include:
