Urine routine is fine does not mean the kidneys are fine. Some patients with normal urine routine examination, but the kidney may have been damaged, commonly found in diabetic nephropathy, hypertensive nephropathy, polycystic kidney, urinary stones and other diseases. 1. Diabetic nephropathy: diabetic nephropathy patients in the early urine routine examination may be normal, but through the urine albumin and other tests will be found to increase urine albumin, this time the kidney function has been damaged. 2. Hypertensive nephropathy: patients with hypertensive nephropathy will mostly show normal in the early urine routine examination, but the glomerular filtration rate will be found to be reduced in the perfect glomerular filtration rate examination. 3. Polycystic kidney: urine routine examination of patients with polycystic kidney usually does not show abnormalities such as proteinuria and hematuria, but the diagnosis of polycystic kidney can be clarified through ultrasonography. 4. Urinary stones: if patients with urinary stones do not have urinary tract infections and urinary tract obstruction, the urine routine may be normal, but the diagnosis of urinary stones can be made through imaging tests. Urine routine does not mean that the kidneys are fine, so it is recommended to improve the relevant tests under the guidance of the doctor to clarify the diagnosis, and timely standardized diagnosis and treatment.
