The total cost of a comprehensive kidney examination, which mainly includes blood creatinine and urea as well as urine routine, 24-hour urine protein quantification, urological ultrasound, and ECT of both kidneys, is about 700-1200 yuan. For kidney examination, the early ones are urine routine as well as urine creatinine and urine protein ratio, which can often detect early kidney disease. Ultrasound of the urinary tract can look for kidney abscesses and symptoms of kidney stones. For the middle and advanced kidney disease, because of the decreasing kidney function, there will be elevated creatinine and urea, accompanied by clinical symptoms of edema and hypertension, then the ECT of both kidneys can be examined, and the examination can clearly indicate the glomerular filtration function. For different periods, the treatment is also different. The treatment of early kidney disease and nephritis can stabilize the kidney function for a long time only by protecting the kidney and reducing the application of urine protein drugs. If there is an elevation of creatinine and urea, or even to the stage of uremia, renal replacement therapy, such as hemodialysis and peritoneal dialysis, is needed.
