Is it possible to have leg amputation if you have kidney problems?

For someone who has diebetes with no kidney that needs to have a leg amputation still recieve a kidney?

Yes. You can -- as long as you qualify for a kidney transplant with all other criteria, an amputation does not disqualify you from the transplant list.
Transplant possible. Patients with severe kidney failure should consider transplant as an alternative to dialysis. History of amputation by itself will not disqualify someone from transplant. In order to qualify for a transplant you have to have funding, be cancer free, and your heart & lungs strong enough. That is an oversimplification, there are other criteria as well. Good luck.
Depends. Transplant lists have strict criteria. If your leg is infected to the point of needing an amputation, most transplant teams would require that you have amputation and heal it prior to transplant. The risk of getting the new kidney infected is too great to undergo transplant while you have an active infection.
