What is the Normal Range for Renal Parenchymal Thickness?

The thickness of renal parenchyma is approximately 1.5 to 2.5 cm. In normal individuals, the kidney is about the size of a fist, with a length of 10 to 12 cm, a width of 5 to 7 cm, and a depth of 2 to 3 cm. As people age, renal function gradually decreases, leading to thinning of the renal parenchyma. In the presence of chronic kidney disease, the thickness of renal parenchyma gradually decreases, resulting in decreased renal function and elevated serum creatinine levels.

Generally speaking, acute kidney injury may lead to enlargement of the kidneys, while chronic kidney injury may result in kidney atrophy. Therefore, in addition to ultrasound examination, further testing of renal function and urine routine is necessary to assess any abnormalities detected on ultrasound. Clinically, color Doppler ultrasound of the renal parenchyma can be used to distinguish between chronic and acute kidney diseases.

Nephrotic syndrome is a serious condition that requires appropriate treatment measures in elderly patients. Nursing and treatment are crucial in daily life. In cases of severe edema and hypoalbuminemia, bed rest should be promptly initiated, and a correct diet with high-quality protein should be provided to ensure adequate caloric intake. Additionally, patients with hyperlipidemia should adhere to a low-fat diet, which constitutes the most basic treatment approach for nephrotic syndrome.

When symptoms of nephrotic syndrome become evident, prompt medical intervention is necessary. Diuretics may be prescribed to reduce edema, and low doses of medication may be used to control the condition. In cases of significant edema and pleural effusion, salt and water intake may be restricted initially. If the effect is not apparent, diuretics may be prescribed to reduce extracellular fluid. This treatment approach can effectively reduce the level of urinary protein in patients.

Adrenal glucocorticoids play a crucial role in the treatment of nephrotic syndrome. When using these medications, patients must strictly follow the doctor's instructions for regular treatment. It is imperative to adhere to the prescribed dosage and avoid arbitrary changes or discontinuation of medication, as this can lead to significant side effects. To effectively manage the condition, it is essential to comply with the doctor's recommendations.
