许多人深受肾结石之痛苦,但并非所有的肾结石都归因于胱氨酸尿症,因此在治疗开始前采取适当的诊断是极其重要的。胱氨酸尿症的特点是肠和肾对二元氨基酸如胱氨酸、赖氨酸、鸟氨酸和精氨酸转运异常结果。造成尿中胱氨酸过多,由于胱氨酸溶解度低,从而在肾脏和尿道形成胱氨酸结石。胱氨酸尿症是氨基酸转运异常病症中最常见的一种。 Many are afflicted with kidney stones, but not all kidney stones are due to cystinuria, so it is extremely important to take proper diagnosis before treatment begins. Cystineuria is characterized by intestinal and kidney abnormalities in the transport of binary amino acids such as cystine, lysine, ornithine and arginine. Caused by excessive cystine in the urine, due to low solubility of cystine, thereby forming cystine stones in the kidney and urethra. Cystineuria is the most common form of abnormal amino acid transport.
