Kidney Health: GFR at 84.1 with No Proteinuria Concerns

The glomerular filtration rate (GFR) is measured at 84.1, and the urinalysis shows no proteinuria?

Hello Dr.
Wu: This year's health check report shows a creatinine level of 1.0, and the estimated glomerular filtration rate (eGFR) is approximately 84.1.
I have a history of chronic urethritis and chronic prostatitis, but the urinalysis results were negative.
Prostate massage did not yield any results, so I had to test the semen, which was reported as normal.
Currently, the physician has diagnosed me with benign prostatic hyperplasia (BPH).
I am taking Harnal Ocas, and my urination has become very smooth, although there is slight urinary retention.
The doctor advised me to continue the medication for 1.5 months before undergoing an ultrasound.
Will this affect my kidneys? Should I take medication or undergo further testing?

Based on your inquiry, your creatinine level is 1.0, and your estimated glomerular filtration rate (eGFR) is 84.1.
Given your age, this indicates a slight decrease in kidney function (normal eGFR > 90).
However, you are currently being treated for benign prostatic hyperplasia, which may be affecting your urinary flow and resistance.
It is possible that your kidney function will return to normal in your next check-up.
Additionally, if you have any issues with the "three highs" (hypertension, hyperglycemia, and hyperlipidemia), it is important to manage them effectively, as they can cause far more damage to the kidneys than the current issue with benign prostatic hyperplasia.
Thank you for your inquiry, and the nephrology department at Changhua Hospital is here to support you.

Understanding kidney health is crucial, especially when interpreting lab results such as the estimated glomerular filtration rate (eGFR) and serum creatinine levels. Your recent lab results indicate an eGFR of 84.1 and a serum creatinine level of 1.0, which are generally considered within the normal range for kidney function. The eGFR is a key indicator of how well your kidneys are filtering waste from your blood. An eGFR above 60 is typically viewed as normal, while values below that may indicate some degree of kidney impairment.

Given that you have a history of chronic urinary tract infections and benign prostatic hyperplasia (BPH), it is understandable to have concerns about how these conditions might affect your kidney health. BPH can lead to urinary retention and obstruction, which, if severe and untreated, could potentially impact kidney function over time. However, since your current eGFR is still within a normal range and you are experiencing improved urinary flow with medication (Harnal Ocas), it suggests that your kidneys are currently functioning well.

The absence of proteinuria in your urine tests is also a positive sign. Proteinuria, or the presence of excess protein in urine, can be an early indicator of kidney damage or disease. Since your urine tests returned negative for protein, this further supports the notion that your kidneys are functioning properly at this time.

In terms of your current treatment for BPH, it is essential to follow your physician's recommendations. The medication you are taking is designed to help alleviate symptoms associated with an enlarged prostate, including urinary retention and difficulty urinating. Regular follow-ups, including ultrasound examinations, will help monitor your condition and ensure that any changes in your prostate or urinary function are addressed promptly.

As for your concerns about whether you need to take additional medications or undergo further testing, it is best to discuss this directly with your healthcare provider. They can assess your symptoms, review your lab results, and determine if any further action is necessary. If your urinary symptoms improve and your kidney function remains stable, additional interventions may not be needed.

In the meantime, maintaining a healthy lifestyle can support kidney health. This includes staying hydrated, eating a balanced diet low in sodium and processed foods, managing blood pressure, and avoiding excessive use of over-the-counter pain medications, which can sometimes affect kidney function. Regular exercise and avoiding smoking can also contribute positively to your overall health.

In summary, your current eGFR of 84.1 and absence of proteinuria are encouraging signs of kidney health. Continue to monitor your urinary symptoms with your physician, and maintain a healthy lifestyle to support your kidneys. If you have any new symptoms or concerns, do not hesitate to reach out to your healthcare provider for further evaluation.
