Urine protein (++) is an abnormal condition, suggesting that the patient has proteinuria and further examination is needed to clarify the cause of proteinuria. There are many causes of proteinuria, which can be caused by surgical diseases, such as severe infections and trauma to the kidney. It can also be caused by internal diseases, such as nephrotic syndrome, nephritis or diabetic nephropathy, which can cause the destruction of the filtration membrane of the kidneys and lead to a large amount of protein leakage from the body, resulting in an increase in protein content in the urine. If the proteinuria is caused by a surgical disease, the proteinuria can disappear quickly through active treatment of the primary disease and the kidneys can return to completely normal function. However, if the proteinuria is of immunogenic, vascular origin or destruction of the glomerulus of the kidney itself, a large amount of proteinuria can occur, which is a medical proteinuria and needs to be treated actively. Usually the treatment period is relatively long and requires long-term regular outpatient follow-up treatment.
