Kidney stones do not cause urine protein, for kidney stones and urine protein are two completely different issues, clinically kidney stones and urine protein belong to two different departments, kidney stones belong to urology, urine protein belongs to nephrology. The following is an introduction to these two diseases. Kidney stones refer to the presence of stone components in the collecting and excretory systems of the kidney, and the most important clinical manifestations are colic and hematuria. Colic refers to the spasm of the ureter during the process of stone discharge downward, so it will show colic. This is one of the main clinical manifestations of kidney stones, but kidney stones do not cause urine protein. The appearance of urine protein is mainly due to the kidney parenchymal lesions, such as in the nephrology clinic often see some diseases, glomerulonephritis, nephrotic syndrome, etc., these parenchymal lesions will cause the appearance of urine protein, so it is not the same as kidney stones, the treatment is also completely different.
