Shining a Spotlight on Kidney Health | World Kidney Day 2024

 

Since the 21st century, chronic kidney disease has become one of the enemies threatening the health of people worldwide. Therefore, the International Society of Nephrology and the International Federation of Kidney Foundations jointly advocate for the establishment of World Kidney Day, designating the second Thursday of March each year as "World Kidney Day" starting in 2006.

March 14, 2024 marks the 19th World Kidney Day. Currently, on average, one in every ten adults globally suffers from chronic kidney disease. In China, the number of chronic kidney disease patients has exceeded 100 million, emphasizing the urgent need for kidney health awareness.


Anatomy of the Kidneys

The kidneys are vital organs located bilaterally on each side of the spine in the retroperitoneal space, outside the peritoneum. Resembling beans, each kidney measures approximately 10 cm in length, 6 cm in width, and 4 cm in thickness, with a weight ranging from 134-148g. Due to the compression from the liver, the right kidney is positioned about 1-2 cm lower than the left kidney.

 


 

How to Assess Kidney Health Using Ultrasound?  

(to detect structural issues such as variations, ectopia, stones, cysts, hydronephrosis, atrophy, etc.)

Bilateral two-dimensional ultrasound: The kidneys exhibit normal size and shape, smooth contours, homogeneous renal parenchymal echoes, well-arranged collecting systems, and no apparent separation or hypoechoic areas.

The kidneys display normal size and shape, smooth contours, homogeneous renal parenchymal echoes, with a cystic echo measuring approximately 47mm X 48mm at the lower pole, clear borders, regular morphology, well-arranged collecting systems, and no apparent separation or hypoechoic areas. (Renal cyst)

The kidneys demonstrate normal size and shape, smooth contours, homogeneous renal parenchymal echoes, with a strong echo measuring approximately 8mm X 5mm at the lower pole, accompanied by posterior acoustic shadowing, well-arranged collecting systems, and no apparent separation or hypoechoic areas. (Renal stone)

How to Maintain Kidney Health

The kidneys, often referred to as the foundation of innate vitality and the source of life, are essential organs responsible for waste excretion and the regulation of fluid and acid-base balance. In daily life, we can preserve kidney health through the following methods:

1. Maintain a Good Sleep Schedule: Adequate sleep is crucial for the repair and detoxification functions of the kidneys. The hours between 11 PM and 3 AM are considered the kidneys' rest and repair period, so it is advisable to try to fall asleep during this time.

2. Adopt a Balanced Diet:

- Low-Salt Diet: Excessive salt intake can lead to edema and increase the burden on the kidneys. Minimize the consumption of fast food and processed foods, which usually contain high levels of salt.

- High-Quality Protein: Consume foods rich in high-quality protein, such as fish, meat, eggs, and dairy products, to ensure the normal functioning of the kidneys.

- Adequate Fluid Intake: Maintain sufficient fluid intake to aid kidney detoxification and maintain fluid balance. Drink at least eight cups of water per day and avoid concentrated urine.

3. Engage in Moderate Exercise: Moderate aerobic exercise helps improve renal blood flow and promote waste excretion. Engage in 3-5 sessions of moderate-intensity exercise, such as walking, jogging, swimming, etc., for 30-60 minutes per session, per week.

4. Avoid Misusing Medications: Many medications require renal metabolism, and their excessive use can damage the kidneys. When using non-prescription drugs, always follow the doctor's advice and avoid long-term excessive use.

5. Undergo Regular Check-ups: Regular kidney ultrasound examinations and kidney function tests, such as creatinine and urine protein levels, help detect early signs of kidney disease and allow for timely intervention.

6. Control Chronic Diseases: Individuals with chronic diseases such as hypertension and diabetes should closely monitor their kidney function and promptly control their condition to reduce the risk of kidney disease progression.

By following these methods, we can effectively maintain kidney health and preserve overall well-being. In daily life, cultivating good habits and caring for our kidneys are crucial for our health.
