Preventing Ureteral Stones and Hematuria: Tips for Hydration and Calcium Citrate - Urology

Preventing ureteral stones and hematuria, especially in individuals with a family history of kidney stones, requires a multifaceted approach. Given your situation where hydration is challenging due to work commitments, it’s essential to implement strategies that can help mitigate the risk of stone formation and manage any potential symptoms effectively.


Importance of Hydration
The cornerstone of preventing kidney stones is adequate hydration. Drinking enough water helps dilute the substances in urine that lead to stone formation. Ideally, individuals should aim for a urine output of at least 2 to 2.5 liters per day, which typically translates to drinking about 3 liters of water daily. If your work schedule makes it difficult to drink water regularly, consider carrying a water bottle with you and setting reminders to take small sips throughout the day. Additionally, consuming hydrating foods, such as fruits and vegetables, can contribute to your overall fluid intake.


Role of Calcium Citrate
Calcium citrate, often referred to as "檸檬酸鈣" in Mandarin, can indeed play a beneficial role in preventing certain types of kidney stones, particularly calcium oxalate stones, which are the most common type. Calcium citrate works by binding to oxalate in the intestines, reducing the amount of oxalate that enters the urine. This is significant because high levels of oxalate can contribute to stone formation. Moreover, calcium citrate can help to increase urinary citrate levels, which inhibit stone formation.

For individuals with a family history of stones, supplementing with calcium citrate may be particularly beneficial. However, it is crucial to consult with a healthcare provider before starting any supplementation, as they can provide personalized recommendations based on your specific health needs and medical history.


Dietary Considerations
In addition to hydration and calcium citrate supplementation, dietary modifications can further help in preventing stone formation. Here are some recommendations:
1. Limit Oxalate-Rich Foods: Foods high in oxalate, such as spinach, rhubarb, beets, nuts, and chocolate, should be consumed in moderation, especially if you have a history of calcium oxalate stones.

2. Reduce Sodium Intake: High sodium intake can increase calcium excretion in urine, raising the risk of stone formation. Aim to limit processed foods and added salt.

3. Moderate Animal Protein: High intake of animal protein can increase the risk of stone formation. Consider incorporating more plant-based proteins into your diet.

4. Maintain Adequate Calcium Intake: Contrary to popular belief, reducing calcium intake is not recommended for those prone to calcium stones. Instead, ensure you are getting enough dietary calcium from sources like dairy products, leafy greens, and fortified foods.


Monitoring and Medical Guidance
Given your family history and previous experiences with kidney stones, regular monitoring through imaging studies and urine tests can help assess your risk and guide preventive measures. If you experience symptoms such as hematuria (blood in urine) or significant pain, it is crucial to seek medical attention promptly.

In conclusion, while hydration is paramount in preventing ureteral stones and hematuria, incorporating calcium citrate supplementation, making dietary adjustments, and maintaining regular medical follow-ups can significantly enhance your preventive strategy. Always consult with a healthcare professional to tailor these recommendations to your specific situation, ensuring the best possible outcomes for your kidney health.
