Kidney stones can cause hematuria and a small amount of proteinuria, if there is a large amount of proteinuria, there may be a combination of nephritis or a combination of other nephrogenic diseases, which need further examination to determine. Kidney stone if caused by the local mucous membrane rupture, this can cause another bleeding, belong to the more common situation. Often cause microscopic hematuria, but the amount of bleeding is more, can cause naked eye hematuria. When the kidney stone is combined with infection, it can cause the local bacterial protein content to increase, and can also lead to a decrease in the amount of protein reabsorbed by the renal tubules, which can cause an increase in the protein content of the urine. However, this increase in protein content is mild and does not cause significant proteinuria. Generally, 24-hour urine is retained for quantitative protein testing, which is less than 150mg/24h or less. If the standard is obviously exceeded, it is recommended to further check the renal function, whether there are stones combined with nephritis. Urine routine dynamic observation and active treatment of the primary pathology, that is, active treatment of kidney stones can be carried out regularly.
