I am a 56 year old healthy female with a history of kidney stones I had a stubborn stone in 1990 , while pregnant with my daughter. After my daughter was born o had a percutaneous catheterization, plus lithotripsy. The doctor couldn t get all of the stubborn out, so I was out on color for a year with frequent check ups. In 1991, I had a second lithographs to remove more of the stone. I was left with only 5-6 small fragments, which are still present. I have dealt with frequent UTI s as a normal part of life. Typically these are not routine it s as they can be resistant to treatment. This week I learned my rb c is 50+ hpf. I also ache all over including the left flank area. I am also exhausted. What could This mean? This week
