Q. How long does it take to pass a kidney stone?
Doctor Answer is medically reviewed by SecondMedic medical review team.
The time it takes to pass a kidney stone can vary widely and depends on several factors, including the size of the stone, its location, and individual factors such as hydration and overall health. Here are some general observations:
1. Small Stones:
- Small kidney stones (usually less than 4 mm) may pass on their own relatively quickly. This process might take days to a few weeks.
2. Moderate-sized Stones:
- Stones that are between 4 mm and 6 mm may take a few weeks to a few months to pass. The time frame can be influenced by factors like hydration, diet, and medical interventions.
3. Large Stones:
- Larger stones (greater than 6 mm) may require more time to pass, and in some cases, they may not pass without medical intervention.
4. Obstruction and Pain:
- The process of passing a kidney stone can be accompanied by intermittent pain and discomfort. Severe pain may occur when the stone moves within the urinary tract.
5. Medical Intervention:
- If the stone is not passing on its own, medical interventions such as extracorporeal shock wave lithotripsy (ESWL), ureteroscopy, or surgical removal may be considered. These interventions can provide a more immediate solution to the problem.
It's crucial to stay well-hydrated during this process, as increased fluid intake can help facilitate the passage of smaller stones. If you suspect you have a kidney stone or are experiencing severe pain, it's important to seek medical attention. A healthcare professional can provide a more accurate assessment of the situation, determine the size and location of the stone, and recommend appropriate measures for pain management and stone passage.
