Just completed Kidneystone Surgery
Background is I got back to back to back to back Ecoli infections in the blood. They found no reason for it until my abdominal ultrasound and followup CT. Turns out I had a stone the size of a USA Quarter (but round). One of the largest they have ever seen in a healthy person. Took four trips to have it removed...can only stay under anesthesia for 2-hours at a time.
A month out now and wow...feel so much better physically. Turns out that kidneystones are hiding places for bacteria. Glad that it is over but wanted to pass on a rule of thumb the doctor informed me of.
2.5L of water a day is enough to keep kidneystones away.
