Cystinuria is a rare etiology of nephroliathiasis but must be considered in the pediatric population and in those patients with recurrent nephrolithiasis. We describe a patient with an unusually large cystine stone burden and our successful multimodality therapy.

Urology, 1980
We report on 9 patients, 5 men and 4 women, with cystine stones. Eight were seen previously at other hospitals, and a total of 18 operations were performed for stones before the diagnosis of cystinuria was made and medical treatment instituted. The pathogenesis and rational for medical treatment is reviewed, and the need for early diagnosis is ...

Abstract The appearances of a cystine kidney stone undergoing dissolution therapy suggested the presence of calcium salts. Contaminants in cystine urinary stones have been investigated by X-ray crystallography. Of 29 stones, four contained sufficient insoluble material to present problems in therapy.

Abstract 35 S- l -cystine was injected intravenously into anaesthetised dogs, and the rate of disappearance of radioactive cystine was measured. Cystine was isolated from the plasma by two different techniques before determination of the radioactivity.

Cystine calculi are radiopaque
American Journal of Roentgenology, 1980Cystine calculi are said to be either radiolucent or radiopaque. In the past, contamination of the calculi with calcium has been given as the reason for a radiopaque appearance. However, most cystine stones are pure cystine and contain essentially no calcium.

Current Opinion in Structural Biology, 1995
Recent reports of the crystal structure of the glycoprotein hormone human chorionic gonadotrophin show that cystine knots are proving to be versatile structural motifs that enable the construction of a variety of proteins with different functional properties.

Journal of Urology, 1986
Historically, cystine stone chemolysis has been approached with 2 different categories of compounds--alkalizing agents (sodium bicarbonate and tromethamine) and, more recently, protonated thiols and disulfide compounds (alpha-mercaptopropionylglycine, N-acetylcysteine and penicillamine).

Cystine Urolithiasis in Ferrets
Veterinary Clinics of North America: Exotic Animal Practice, 2020Urolithiasis in captive domestic ferrets has previously been predominantly struvite uroliths, although more recent laboratory submissions show a shift to predominantly cystine uroliths. Genetic mutations for cystinuria have been identified in dogs, and it is suspected that underlying genetic mutations are partly responsible for this disease in ferrets.

Uptake of cystine by cystine-depleted fibroblasts from patients with cystinosis
Biochemical and Biophysical Research Communications, 1981Abstract [ 35 S]L-cystine uptake was measured in cultured skin fibroblasts from patients with nephropathic cystinosis, pretreated with cysteamine to deplete their cystine pools. The uptake was greater in the cystinotic cells than in normal cells.

Comparative Uptake of Selenium by Low Cystine and High Cystine Proteins
Canadian Journal of Biochemistry, 1971Purified preparations of skin collagen, tendon gelatin, and thymus histones, isolated from various animals administered 75Se-labeled selenite, contained only a trace of cystine (plus [Formula: see text]-cystine) and incorporated very little 75Se activity.
