25% Kidney Atrophy: Functionality, Surgery, and Care Tips

A 25% reduction in kidney size indicates atrophy, but the kidney may still retain some function. Whether surgery is necessary for removal depends on various factors, including the underlying cause of the atrophy, the remaining kidney function, and any associated symptoms. A thorough evaluation by a healthcare professional is essential to determine the best course of action?

Hello Dr.
Chen,
I am a kidney stone patient.
Two years ago, a friend introduced me to traditional Chinese medicine, which helped me pass a significant number of stones.
I haven't had any issues for the past two years, so I stopped taking the herbal medicine.
Recently, I had an ultrasound and discovered that my left kidney has atrophied by 25%.
The doctor advised me that the left kidney has lost its function and recommended a left nephrectomy due to concerns that the compromised kidney could lead to a bacterial infection affecting my healthy right kidney.

I would like to ask for your professional advice and information regarding the following:
1.
Does the left kidney, which is 25% atrophied, still have any functional capacity? If it has no function, is removal necessary? What are the risks involved?
2.
Should I take any medications, and are there treatment options available?
3.
Are there specific precautions I should take in my daily life?
4.
What could have caused this condition?
5.
Since I only have one functioning kidney, should my daily dietary intake be halved compared to someone with two healthy kidneys? For example, if a normal person drinks 1000cc of water a day, should I limit myself to 500cc? However, I also have a stone issue, so I am confused about how much water I should be drinking.

I am very worried and would greatly appreciate your help in answering these questions.
Thank you very much!

More Info

Understanding kidney atrophy, particularly a 25% reduction in kidney size, is crucial for managing your health effectively. Kidney atrophy can occur due to various reasons, including chronic conditions, previous infections, or obstruction, such as from kidney stones. Here’s a comprehensive overview addressing your concerns:
1. Functionality of the Atrophied Kidney: A 25% atrophy in the kidney indicates a significant reduction in its functional capacity. While the kidney may still perform some functions, its efficiency is compromised. If your doctor has advised that the left kidney has lost its functionality, it may be due to irreversible damage. In such cases, the risk of infection or complications can increase, which is why your doctor may recommend surgical removal (nephrectomy) to protect the healthy kidney.

2. Surgical Considerations: Nephrectomy is generally safe and can prevent potential complications from an atrophied kidney, such as infections that could affect the remaining kidney. However, like any surgery, it carries risks, including bleeding, infection, and complications related to anesthesia. Discuss these risks with your healthcare provider to make an informed decision.

3. Medication and Treatment Options: There are no specific medications that can reverse kidney atrophy. However, if there are underlying conditions contributing to kidney damage, such as hypertension or diabetes, managing these conditions is critical. Your doctor may prescribe medications to control blood pressure or manage blood sugar levels, which can help protect the remaining kidney function.

4. Daily Care and Lifestyle Adjustments: After losing a kidney, it’s essential to adopt a healthy lifestyle to support the remaining kidney. Here are some tips:
- Hydration: While staying hydrated is crucial, especially with a history of kidney stones, you should consult your doctor about the appropriate amount of fluid intake. Generally, individuals with one kidney may not need to drastically reduce their fluid intake, but they should avoid excessive consumption.

- Diet: Focus on a balanced diet low in sodium and protein, as excess protein can strain the kidneys. A nutritionist can help tailor a diet plan that meets your needs, especially considering your history of kidney stones.

- Regular Check-ups: Regular follow-ups with your healthcare provider are essential to monitor kidney function and overall health. Blood tests to check creatinine levels and other kidney function markers will be important.

5. Causes of Kidney Atrophy: The atrophy could be due to chronic kidney stones, previous infections, or other underlying health issues. It’s essential to address the root cause to prevent further complications. If kidney stones were a significant issue, you might need to explore preventive measures to avoid future stone formation.

6. Fluid Intake Confusion: It’s understandable to feel confused about fluid intake. While it’s true that individuals with one kidney may need to be mindful of their hydration, the recommendation to drink less than a person with two kidneys is not absolute. The key is to find a balance that keeps you hydrated enough to prevent kidney stones while not overloading your remaining kidney. Your healthcare provider can help you determine the right amount based on your specific circumstances.

In conclusion, while a 25% atrophy in your kidney is concerning, proactive management and lifestyle adjustments can help maintain your health. Discuss all your concerns with your healthcare provider, who can guide you through the decision-making process regarding surgery and post-operative care. Remember, maintaining a healthy lifestyle and regular monitoring are vital for preserving the function of your remaining kidney.
