Normally 2 days: The time to pass a stone is really the same for men and women. Most stones pass in the forst 48 hours. The chance of it passing after a week is around 50%.

Hydration first!: The size of the stone does not correlate well to the intensity of the pain. The nearly unbearable pain of "ureteral colic" is from spasm of the muscular ureter. Although 50% probability to pass on its own within a few days, a 6mm stone sometimes will get stuck and fail to progress. Usually after 5 days, i recommend having the stone extracted with a ureteroscope as an outpatient.

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.

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.

See a urologist: It could take hours or days. You should be under the care of a urologist, who can guide your management. At some point a more proactive approach to your kidney stones will be necessary. Don't try to mange this alone. Good luck.

Hard to say.: Depends on size and even then depends upon patient factors as well. Some stones never pass and some try to pass but get stuck. Somewhere between a few minutes and a few days is usually the norm.

Kidney stone: It depends on the size of the kidney stone if it's going to pass with only medication or surgery. You have to attend an urologist so they can give you a treatment plan.
