How long does a transplanted kidney last?

Dr.Vikas Agarwal, 3 mins read

A kidney transplant is a life-saving and life-modifying procedure for patients suffering from end-stage renal disease. It is considered a better option than dialysis as it improves quality of life and survival rate and is cost-effective in the long term. But with that, one common question often arises, i.e., "How long will my transplanted kidney last?". 

Well, it depends on whether the kidney transplant is from a living donor or a deceased donor. Usually, the former has a higher life expectancy compared to the latter. This guide will discuss this in detail. So, let’s get started.

Factors affecting kidney transplant longevity

The lifespan of a transplanted kidney varies depending on several factors. These factors include:

• Donor type: As discussed earlier, kidneys from living donors usually tend to last longer than those from deceased donors. On average, a kidney transplant from a living donor lasts about 15 to 20 years. On the other hand, a kidney transplant from a deceased donor lasts about 8 to 12 years. This is because living donors are chosen after the utmost matching and fitness check, ensuring that the kidney is compatible and healthy and has good functional strength. Other than this, a kidney from a living donor comes with shorter wait times and presurgical planning. 
• Age and health of the donor: Kidneys from younger donors and those with fewer or no health issues tend to function longer compared to older donors with comorbidities. 
• Recipient's overall health: Patients with underlying health conditions, such as diabetes, high blood pressure or severe complications, may experience shorter graft survival compared to those who receive a transplant at the earliest and have no other chronic problem, or they have managed those issues properly.  
• Immunosuppressive medications: Adherence to immunosuppressive medications is crucial to prevent rejection and ensure long-term graft survival.
• Lifestyle factors and aftercare: Care after surgery has a huge importance in recovery and survival. Thus, maintaining a healthy lifestyle, including a balanced diet, regular exercise, and stress management, can help support graft longevity. Also, follow your doctor’s prescription as a ritual. 

Tips for Long-Term Survival

To ensure the longevity of your transplanted kidney, following the tips below can help:

Adhere to medication regimens

Take immunosuppressive and other medications as directed to prevent rejection. If you're going out, always carry your medications. Set a reminder on your phone so you never miss out on your medications. Also, ensure hygiene and safety of the incision site. 

Attend follow-up appointments

Periodic check-ups with your healthcare team can help identify potential issues early. Also, this will help in adjusting your medications and determining your current health status.

Maintain a healthy lifestyle

Eat a balanced diet, exercise regularly, ensure personal and home hygiene, and manage stress to support overall health. You can ask your doctor, dietitian and physiotherapist about a personalised diet and exercise regimen. 

Monitor for signs of rejection

In case you see any abnormal signs, such as fever, fatigue, or changes in urine output, consult your doctor. At the time of discharge from the hospital, your doctor will help you on what signs can be normal and when you should call for help.

Takeaway!

While the lifespan of a transplanted kidney varies, many patients report long-term graft survival and improved quality of life. Above, we have discussed the factors that affect the longevity of the transplanted kidney and the tips for long-term graft survival.
