Renal echogenicity is an ultrasound descriptor that often indicates the possible presence of renal space-occupying lesions such as kidney stones, complex renal cysts or intracystic calcifications, and tumors. If kidney echogenicity is detected by ultrasound, it is most likely due to kidney stones. When crystalline material in the urine decreases in solubility or increases in concentration due to a variety of factors, and eventually collects in the kidneys to form stones, patients with kidney stones usually experience symptoms such as lower back pain, painful urination, or inability to urinate. Renal cysts with higher density of some of the cystic fluid may also present with the imaging feature of strong echogenicity of the kidney; similarly with renal tumors, benign tumors are usually not life-threatening and have good postoperative outcomes, while malignant tumors require radical renal transplantation or nephrectomy. If you find strong echogenicity in the kidney, we suggest you to seek further medical advice to clarify your condition and treat it under the guidance of your physician.
