These stones can get stuck in the kidneys, bladder, or anywhere in the urinary tract. Most people with cystinuria have recurring stones. It is a lifelong condition that can be controlled, but not cured.
What is the cause of cystinuria?
Cystinuria is caused by too much cystine in the urine. Normally, most cystine dissolves and returns to the bloodstream after entering the kidneys. People with cystinuria have a genetic defect that interferes with this process. As a result, cystine builds up in the urine and forms crystals or stones.
What does cystinosis mean?
Cystinosis is a rare genetic, metabolic, lysosomal storage disease caused by mutations in the CTNS gene on chromosome 17p13 which results in an abnormal accumulation of the amino acid cystine in various organs and tissues of the body such as the kidneys, eyes, muscles, pancreas and brain.
What is a normal urine pH?
According to the American Association for Clinical Chemistry, the average value for urine pH is 6.0, but it can range from 4.5 to 8.0. Urine under 5.0 is acidic, and urine higher than 8.0 is alkaline, or basic. Different laboratories may have different ranges for “normal” pH levels.
How are cystine stones formed?
Cystine stones are caused by a collection of the amino acid cystine. This occurs in people with a condition called cystinuria. Cystinuria is passed down through a family. Cystine forms crystals that combine to create stones in the urine.
What is Hartnup's disease?
Hartnup disease (also known as “pellagra-like dermatosis” and “Hartnup disorder”) is an autosomal recessive metabolic disorder affecting the absorption of nonpolar amino acids (particularly tryptophan that can be, in turn, converted into serotonin, melatonin, and niacin).
What is black urine disease?

What are the symptoms of cystinosis?
Signs and symptoms of nephropathic infantile cystinosis include the following: Multiorgan involvement: May be mild to severe. Polyuria, polydipsia, dehydration, vomiting, metabolic acidosis. Hypophosphatemic rickets. Constipation. Failure to thrive, poor/loss of appetite.
What is the life expectancy of someone with cystinosis?
Nephropathic and intermediate cystinosis were once progressively fatal disorders, with a lifespan for the infantile form of less than 10 years. However, the development of cystine depleting therapies along with improvements in kidney transplantation have extended the lifespan well into adulthood.
Why does urine smell like Sulphur?
