In reference to painful kidney stones......what is the cut off diameter where a stone might pass thru into the urine?? {I forgot} :oops:
<4-5mm are more likely to spontaneously pass through.

The rule of thumb I was taught, and continue to go by:

<5mm - likely will pass, pain control & encourage hydration (+/- Uroxatral)

5-10mm - dicey, do all of the above but give the Urologist a call to see if he's interested in going after it

>10mm - unlikely to pass, Urology will want to see them

"Painful" stones implies obstruction at which point I believe it is recommended to remove if there is failure of the stone to progress even if the stone is 4mm. I got this info from here:
Reilly, Robert F. (2005). Nephrology in 30 Days. UNC Press. pp. 195. ISBN 1882886208
Let me know if you have any other guidlines you know of.
