More Details· Cystine tends to precipitate out of urine and form stones (calculi) in the urinary tract. Small stones are passed in the urine. However, big stones remain in the kidney (nephrolithiasis) impairing the outflow of urine while medium-size stones make their way from the kidney into the ureter and lodge there further blocking the flow of urine (urinary obstruction).
More DetailsKidney stones can have a variety of compositions such as calcium, uric acid, struvite and cystine stones. They are formed by deposition of toxic compounds in the kidneys . An increased deposition of toxic compounds may result in the formation of large-sized kidney stones…
More DetailsKidney stones, also called nephrolithiasis, urolithiasis, or renal calculi, can form in the kidneys, but also in the ureters, bladder, or the urethra. They appear when solutes in the urine precipitate and crystalize.
