Introduction

Introduction of Cystinuria:
Cystinuria denotes the pathological condition in which urine of the patient has cystine found in it by laboratory assessment which is indirectly because of the presence of cysteine stones in kidney. Cystinuria is a condition that gets passed down in families with kidney stones made up of an amino acid called cysteine. These stone can get formed in the kidney, ureter, and bladder.

History

Causes, incidence, and risk factors of cystinuria:
You have symptoms of cystinuria; you must have inherited the faulty gene from both of your parents! This is the simple rule that goes on with the idea of genetics of cystinuria. Cystinuria is caused and detected by excess of an amino acid called cystine in the urine. In kidneys, most of the cystine normally dissolves and goes back to blood. In patients of cystinuria there is a genetic defect that interferes with this normal physiology. Eventually the level of cysteine builds up in the urine and forms stones or sometime crystals, which get stuck anywhere in the way from kidneys, ureters, to bladder. About one in every 10,000 people has cystinuria and this is alarming.
