Compared to brain-dead or heart-dead donor kidney, living kidney transplantation is easy to schedule, has a high success rate, low chance of rejection after transplantation, less medication, better long-term results than cadaveric donor kidney, etc. However, there are many anxieties for the donor: Is it safe to cut off a kidney directly? Will all the body functions be reduced with one kidney missing? First of all, it is clear that the kidney transplant donor needs to be strictly evaluated before surgery, and must be a healthy person. If he suffers from kidney damage diseases such as hypertension, diabetes, or nephritis, he cannot be a living kidney donor; if he suffers from infectious diseases such as hepatitis B, hepatitis C, syphilis, etc., the surgery can only be arranged after the disease is completely controlled. After the surgery, the kidney donor is not necessarily more prone to hypertension and urological diseases than ordinary people, and there is no major difference in urination, sexual function and diet and exercise. However, after all, one kidney is still missing, so if you suffer from diabetes, hypertension, nephritis or trauma to the kidney afterwards, the damage to your body will definitely be very great, so you should pay more attention to love and care in general.
