Neurogenic *sp* bladder runs in the family. Now that's a problem! I have "thick" bladder walls which can make things difficult. I make sure my diet has enough free calcium to bind the calcium oxalate and keep that particular stone from forming, 300 mg Calcium at least. Tums or Milk. Get enough of the The big Four: Milk, Citric Acid drinks, lots of water, and avoid animal proteins. Been so long since I have raped my kidneys with a HydroUreter or infections I forgot.
