Transplantation is not done for kidney stone formers, unless permanent kidney failure becomes a complication of the chronic kidney stone disease. I am a nephrologist and not a surgeon. I do not perform lithotripsy. This is a urological problem and should be addressed to his urologist. In this situation, it may be necessary for your partner to have a stone evaluation and determine why he is having stones. This will lead to a more specific diagnosis as to why he is a stone former. Your partners should see a urologist or a nephrologist who is interested in kidney stone disease.
