I have a few staghorn stones in 1 kidney and it's working at 7% so it will be removed. Other one is fine. Blood showed nothing unusual and urine test showed xxx white cells and a bit of blood. I've been feeling tired and generally unwell. Any Ideas?

A good plan . With only 7% function removal sounds like the best plan. At only 32 years of age this probably a birth defective kidney and stone removal would only leave you with a problem. As we often say in urology, rather than remove the stone now and the kidney later when it is still sick.....do the last operation first.
