How long is it supposed to it take for a kidney stone to pass?

Depends upon size &: Shape. Can't ever predict passage time. Stones larger than 6mm in diameter will often not pass. Stones stuck in upper ureter take longer & r less likely to pass than stones stuck in lower ureter. Small stones pass quicker withincreased hydration water is best) + tamsulosin can help ureter to dilate, which speeds up possible passage. Urologist is best person to advise & manage kidney stone problems.

Most in 2 days: Most stones if they are going to pass will pass in the first 48 hours. The chances after that start to decrease. The chances probably never go to zero but after a week, the chances are probably around 50% of it ever passing.

? Size & location: Small stones pass quicker than large ones. Stones greater than 5 - 6 mm in diameter may never pass. Stones with spikes, even if small, may remain stuck indefinitely. Stones in lower ureter more likely to pass & pass quicker than stones in upper ureter. Good hydration & taking tamsulosin speeds up passage. Can not give you absolute or likely time span without details. Good luck.

It varies.: I depends on the size, location and composition of the stone. The smaller it is the more likely is will pass quickly. But even small stones can sometimes require intervention.
