I was diagnosed on monday with 4mm by 6mm kidney stone is it passable still have the urge to pee but today the urge is less am i gonna passpass it?

Ureteral stone: 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.

Possible: As size increases, it is less likely to pass on its own. A good rule of thumb is that a 5 mm stone will pass 50% of the time. This decreases to 10% at 9 mm.
