What is the cause of the double kidney echo enhancement?

Color Doppler ultrasound showed enhanced echo of bilateral kidney parenchyma, which may be caused by acute pyelonephritis, chronic kidney disease or early B-ultrasound manifestation of glomerulonephritis. Further examination is required, including urine routine, urine culture, 24-hour endogenous creatinine clearance rate, urine osmotic pressure and urine microprotein. These indicators are clearly diagnosed and then targeted treatment. If acute pyelonephritis is /confirm/ied, the renal parenchyma echo will return to normal after oral sensitive antibiotics, such as nitrofurantoin tablets and sulfadiazine tablets, for 2-4 weeks. If chronic kidney disease or glomerulonephritis is confirmed after examination, it is necessary to take Jinshuibao capsules or Bailing capsules orally for at least 3-6 months before the disease can be controlled.
