Your inquiry covers a wide range of topics; here is a brief response.
If you would like to discuss further, please feel free to call (07) 3422121 ext 20501.

Medications that may harm the kidneys include: pain relievers, especially non-steroidal anti-inflammatory drugs (NSAIDs); antibiotics, particularly aminoglycosides; contrast agents used in radiological examinations (commonly in CT scans or angiography); unknown herbal remedies or black pills; and traditional Chinese medicines containing aristolochic acid, such as Stephania tetrandra and Akebia quinata.
The causes of hematuria can be broadly categorized into three main types: (1) diseases of the kidneys themselves, (2) diseases of the urinary tract (non-renal bleeding), and (3) systemic diseases.
The most common causes are inflammation of the prostate or bladder, followed by urinary tract stones, tumors, and glomerulonephritis.
If you experience pain while urinating and see a little blood, along with significant pain in the lower abdomen, it may indicate cystitis or urethritis.
Please consult a urologist or nephrologist for evaluation.
Sincerely,
Dr.
Yao-Min Hung, Attending Physician, Nephrology Department, Kaohsiung Veterans General Hospital.

More Info

Kidney damage can be a serious concern, especially when it is related to medication use. Certain medications are known to have nephrotoxic effects, meaning they can cause damage to the kidneys. Understanding which medications can lead to kidney issues, recognizing the symptoms, and knowing how to address these problems is crucial for maintaining kidney health.

Medications That Can Cause Kidney Damage
1. Non-Steroidal Anti-Inflammatory Drugs (NSAIDs): Commonly used for pain relief, NSAIDs such as ibuprofen and naproxen can lead to acute kidney injury, especially when taken in high doses or over prolonged periods.

2. Antibiotics: Certain antibiotics, particularly aminoglycosides (like gentamicin), can be nephrotoxic. They are often used to treat serious infections but require careful monitoring of kidney function during treatment.

3. Radiocontrast Agents: Used in imaging studies like CT scans, these agents can cause contrast-induced nephropathy, particularly in patients with pre-existing kidney conditions.

4. Herbal Supplements: Some herbal products, especially those containing aristolochic acid (found in certain traditional Chinese medicines), are known to cause kidney damage.

5. Chemotherapy Agents: Drugs used in cancer treatment, such as cisplatin, can also have nephrotoxic effects.

6. Proton Pump Inhibitors (PPIs): Long-term use of PPIs for acid reflux has been associated with an increased risk of chronic kidney disease.

Symptoms of Kidney Damage
Symptoms of kidney damage can vary widely. Some common indicators include:
- Changes in Urination: This may include decreased urine output, dark urine, or blood in the urine (hematuria).

- Pain: Pain in the lower back or abdomen can be a sign of kidney issues, especially if it is accompanied by other symptoms.

- Swelling: Fluid retention can occur due to impaired kidney function.

- Fatigue: A general feeling of tiredness or weakness can also be a symptom.

- Nausea and Vomiting: These can occur as toxins build up in the body due to reduced kidney function.

Addressing Kidney Damage
If you suspect that a medication is causing kidney damage, it is essential to take the following steps:
1. Consult a Healthcare Provider: If you experience symptoms such as pain during urination, blood in urine, or abdominal pain, seek medical attention promptly. A healthcare provider can perform tests to assess kidney function, such as blood tests (creatinine and blood urea nitrogen) and urine tests.

2. Review Medications: Discuss all medications you are taking with your healthcare provider, including over-the-counter drugs and supplements. They may suggest alternatives or adjust dosages.

3. Hydration: Ensuring adequate hydration is crucial, especially when taking medications known to affect the kidneys. Drinking enough water can help dilute substances in the urine and reduce the risk of kidney damage.

4. Monitor Kidney Function: Regular monitoring of kidney function is essential, especially for individuals on long-term medications known to be nephrotoxic.

5. Lifestyle Modifications: Maintaining a healthy lifestyle, including a balanced diet, regular exercise, and avoiding excessive alcohol and tobacco use, can help support kidney health.

Conclusion
In summary, several medications can lead to kidney damage, and recognizing the symptoms is vital for early intervention. If you experience pain during urination, blood in your urine, or abdominal pain, it is crucial to consult a healthcare provider for a thorough evaluation. They can help determine the cause of your symptoms and recommend appropriate treatment or adjustments to your medication regimen. Always prioritize open communication with your healthcare team regarding any concerns about your medications and kidney health.
