    <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.
