Small nodular foci in both kidneys may not necessarily be cancer, but may also be kidney cyst, kidney abscess and other problems. The presence of double kidney nodules cannot be directly judged as a certain disease, and it needs to be further diagnosed by combining physical examination, blood routine, blood biochemistry, urinalysis, MRI, CT, ultrasound and other examinations. If the nodular foci are malignant tumors, they are characterized by rapid growth, burrs on the borders, and lack of a complete periphery, and will spread and metastasize. Small nodular foci in both kidneys may also be renal cysts, such as simple renal cysts, polycystic kidneys; or renal abscesses, such as renal cortical abscess, renal corticomedullary abscess. The appearance of double kidney nodules should actively cooperate with the doctor for treatment, not timely treatment patients may appear hematuria, lumbago, abdominal pain and other symptoms, and even complications such as urinary tract infection, renal failure and other complications, seriously affecting the patient’s life and work. Patients with bilateral renal nodule foci should usually develop good habits, do not stay up late, to ensure sufficient rest time, if the patient’s body temperature, urine volume and other abnormalities, should be timely to the hospital.
