[Dune] How do the Fremen deal with kidney stones.

Kidney stones can be caused by not drinking enough water, this obviously going to be common on Arrakis  How would the stillsuits deal with passing a kidney stone? Would a solid in the moisture recycling system cause a problem?

The fremen drink a good deal of water. They constantly recycle it losing only a small percentage throughout the day. So they're not dehydrated or drinking on rations just drinking the same fluid over and over and over with periodic refills.
