How log does it take to pass a small kidney stone? i have been dealing with the pain for over a week to a week and a half ago. i urinate frequently.

Tamsulosin: It can take a long time or you may not pass it without surgery. Tamsulosin is a prescription drug that increases your chance of passing a stone less than 8 mm up to about 80%. Seek emergent care if you develop a fever with this stone.

Size: Depends on size of stone. If its bigger than 5mm, it might not pass.

Not predicted: When the stone traps in a narrow spot in urinary tract it causes pain. With drinking 2-3 lit of water and liquid over night and day and diuretic use with ample walking may washed out or just displaced to a bigger area that doesn't cause pain and stay there for a while. The stone analysis helps to choose the proper diet and medication to prevent recurrence. Noninvasive intervention may be needed.
