Kidney stones are one of the most common disorders of the urinary tract. The length of time a kidney stone lasts depends on a variety of factors, including the size and type of stone, the location of the stone, and the individual’s overall health. In general, small stones can pass through the urinary tract on their own within two to eight weeks. Larger stones may require medical intervention or longer periods of time to pass.
Size
The size of a kidney stone is one of the most important factors in determining how long the stone will last. Smaller stones, usually measuring less than 5 millimeters (mm) in diameter, may pass on their own in a few days or weeks. Larger stones, those measuring 5 mm or more, may take several weeks or longer to pass.
Type
The type of stone is also a factor in determining how long it will last. The two most common types of kidney stones are calcium oxalate and uric acid stones. Calcium oxalate stones are usually composed of calcium and oxalate, and may take longer to pass than uric acid stones. Uric acid stones, on the other hand, are usually composed of uric acid and may pass more quickly.
Location
The location of a kidney stone is also a factor in how long it will last. Stones located in the ureter, the tube connecting the kidney to the bladder, may take longer to pass than stones located in the kidney itself. This is because the ureter is narrower than the kidney and the stone may become stuck, making it more difficult to pass.
Overall Health
The individual’s overall health is also a factor in how long a kidney stone will last. If the individual is otherwise healthy, the stone may pass more quickly. On the other hand, if the individual has other medical conditions, such as diabetes or high blood pressure, the stone may take longer to pass. Additionally, certain medications or lifestyle changes may help to speed up the process.
In general, kidney stones can last anywhere from a few days to several weeks, depending on a variety of factors, including size, type, location, and overall health. In some cases, medical intervention may be necessary to help the stone pass more quickly.
