How Long Does It Take for Kidney Stones to Shrink and Pass? - Internal Medicine

When it comes to kidney stones, the time it takes for them to shrink and pass can vary significantly based on several factors, including the size of the stones, their location, and individual patient factors such as hydration levels and overall kidney function. In your case, you have two kidney stones measuring 0.7 cm, which is about 7 mm. Generally, stones of this size can potentially pass on their own, but the process can take anywhere from a few days to several weeks.

The primary recommendation from your physician to increase your water intake is indeed one of the most effective strategies for managing kidney stones. Drinking plenty of fluids helps to dilute the urine, which can reduce the concentration of minerals that form stones and may help flush them out. Your goal of consuming at least 2800 ml of water daily is commendable, as staying well-hydrated is crucial in managing kidney stones.

In addition to hydration, there are a few other strategies you might consider to help facilitate the passage of kidney stones:
1. Dietary Adjustments: Depending on the type of stones you have (calcium oxalate, uric acid, struvite, or cystine), certain dietary changes can be beneficial. For instance, reducing sodium intake, limiting foods high in oxalates (like spinach, nuts, and chocolate), and ensuring adequate calcium intake can help manage calcium oxalate stones. Consulting with a dietitian who specializes in kidney health can provide personalized recommendations.

2. Physical Activity: While you mentioned doing jumping exercises, which can help, it's also important to engage in regular physical activity. Activities that involve movement can help facilitate the movement of stones through the urinary tract. However, be cautious and avoid any high-impact activities that could cause discomfort.

3. Pain Management: If you experience any pain or discomfort, over-the-counter pain relievers such as ibuprofen or acetaminophen can help manage symptoms. However, consult your doctor before taking any medication, especially if you have any underlying health conditions.

4. Monitoring Symptoms: Keep track of any symptoms you experience, such as pain, changes in urination, or blood in the urine. If you notice any significant changes or if the pain becomes severe, it's important to seek medical attention promptly.

5. Follow-Up Imaging: Since your doctor has suggested a follow-up ultrasound in a year, it may be beneficial to have more frequent check-ups if you feel that the stones are not passing or if you experience any complications. Regular imaging can help monitor the size and location of the stones.

6. Consider Medical Intervention: If after a reasonable period (usually a few weeks to a couple of months) the stones have not passed, or if they cause significant symptoms, further medical intervention may be necessary. This could include options like lithotripsy (shock wave therapy) or ureteroscopy, depending on the specific circumstances.

In summary, while the natural passage of kidney stones can take time, maintaining hydration, making dietary adjustments, and staying active can all contribute to the process. If you continue to feel that the stones are not passing or if you have concerns about your symptoms, do not hesitate to reach out to your healthcare provider for further evaluation and management.
