Understanding the procedure
๐ Overview
What this procedure is
A kidney transplant is a surgery where a healthy kidney from another person is placed into your body. This new kidney takes over the job of filtering your blood, which is a task your own kidneys can no longer do well. Because the body can function perfectly well with just one healthy kidney, most people only receive one during the transplant.
The healthy kidney can come from two different sources. A living donor is a person, often a family member or friend, who chooses to donate one of their kidneys. A deceased donor is someone who has recently passed away and chose to donate their organs. Your clinician may discuss which option is best for your specific situation.
During the surgery, the new kidney is usually placed in the lower part of the abdomen. In most cases, your original kidneys are left where they are unless they are causing specific problems like infection or high blood pressure.
What it treats or fixes
This procedure is used to treat kidney failure, also called end-stage renal disease. This happens when the kidneys have lost about 90% of their ability to work normally. When kidneys fail, they can no longer remove waste, extra salt, and water from the blood, which can cause dangerous levels of fluid and toxins to build up in the body.
Common conditions that may lead to kidney failure include:
- Long-term, uncontrolled diabetes.
- Chronic high blood pressure.
- Polycystic kidney disease, which is a condition where cysts grow in the kidneys.
- Glomerulonephritis, which is an inflammation of the kidney's tiny filtering units.
For many people, a transplant is an alternative to dialysis. Dialysis is a treatment that uses a machine to filter the blood. While dialysis is life-saving, a transplant often allows for a more flexible lifestyle and may help people live longer than they would on dialysis alone.
How common it is & where it's done
Kidney transplant is one of the most common types of organ transplant surgeries performed today. Because it is a complex process, it is done at specialized transplant centers. These centers are usually located within large hospitals and are staffed by a team of experts, including surgeons and nephrologists (doctors who specialize in kidney care).
Thousands of kidney transplants are performed every year in the United States and Canada. While many people wait for a kidney from a deceased donor, the use of living donors has become a very common and successful way to shorten the wait time for a transplant.
Your clinician may refer you to a transplant center for an evaluation. This evaluation helps the transplant team decide if the procedure is the right choice for your health and helps you understand the steps involved in finding a donor kidney.

โญ Key Patient Questions (Quick Answers)
Recovery: What to Expect
After your surgery, you will likely stay in the hospital for several days so your care team can monitor your new kidney. You may feel some soreness around the area where the surgery was done, but your clinician will help manage any discomfort. Most people are encouraged to get up and walk shortly after surgery to help with healing and blood flow.
A key part of recovery is learning about your new medications. You will take "anti-rejection" drugs, which are medicines that help prevent your immune system from attacking the new kidney. Your team will schedule frequent check-ups during the first few months to ensure the kidney is working correctly and to adjust your medicine doses.
Risks & Possible Complications
While kidney transplants are common, they do come with some risks. These can include surgical issues like bleeding or blood clots. There is also a risk of infection because the medications used to protect your kidney also lower your body's ability to fight off germs. Your clinician may suggest ways to avoid getting sick, such as frequent handwashing.
The most important risk to watch for is rejection. This happens if your body treats the new kidney like a foreign object. Your clinician may tell you to call the office if you notice any of the following:
- A fever or flu-like symptoms.
- Sudden weight gain or swelling in your ankles.
- Pain or tenderness over the site of the new kidney.
- A significant decrease in how much you urinate.
Outcomes & Long-Term Results
For many people, a successful transplant offers a better quality of life and more freedom than dialysis. Most patients find they have more energy and fewer restrictions on what they can eat and drink. While a transplant is a treatment rather than a permanent cure, many donated kidneys function well for many years or even decades.
Your long-term success depends heavily on taking your medications exactly as directed. Even if you feel perfectly healthy, missing doses can put the kidney at risk. Regular blood tests and visits with your transplant team will help keep your new kidney healthy for as long as possible.
Emotional Support & Reassurance
It is completely normal to feel a range of emotions, from relief to worry, throughout the transplant process. You are managing a big life change, and it is okay to ask for help. Your transplant center often has social workers, counselors, and support groups specifically for people in your situation.
Staying connected with your family, friends, and medical team can make a big difference. Remember that your clinicians are there to support you every step of the way. With the right care and a positive support system, most patients successfully navigate the transition to life with a new kidney.
๐งฌ Why This Surgery Is Performed
Why doctors recommend it
Doctors usually recommend a kidney transplant when a person has end-stage renal disease. This is a condition where the kidneys have lost about 90% of their ability to function normally. Because the kidneys are responsible for filtering waste and extra fluid from the blood, the body cannot stay healthy when they fail.
While dialysis (a treatment that uses a machine to filter the blood) can do some of this work, your clinician may recommend a transplant as a more permanent solution. Research shows that a transplant often helps people live longer and enjoy a better quality of life compared to staying on dialysis for many years.
Urgent vs planned treatment
A kidney transplant is almost always a planned procedure rather than an emergency surgery. Because it takes time to find a compatible donor and complete medical testing, the process often begins months or years before the surgery takes place. Your clinician may suggest a preemptive transplant, which means receiving a new kidney before you even need to start dialysis.
The timing of the surgery often depends on the type of donor available:
- Living donor: If a healthy person (like a family member or friend) chooses to donate a kidney, the surgery can be scheduled for a time that works for everyone.
- Deceased donor: If you are on a national waiting list, the surgery happens when a matching kidney becomes available. This requires being ready to go to the hospital on short notice.
Goals of treatment
The primary goal of a kidney transplant is to restore the bodyโs natural ability to filter blood. A successful transplant allows the new kidney to take over the work that the failing kidneys can no longer do. This helps prevent the buildup of dangerous toxins in the bloodstream.
Success in this treatment often means:
- More energy: Many people feel stronger and less tired once their blood is being filtered properly.
- Fewer restrictions: Patients often have more freedom in their diet and the amount of fluids they can drink.
- Independence: A major goal is to eliminate the need for dialysis, which allows for more flexibility with work, travel, and daily life.
- Long-term health: The procedure aims to reduce the risk of heart problems and other complications associated with kidney failure.
๐ฅ Who May Need This Surgery
Who may benefit
A kidney transplant is a surgery to place a healthy kidney from a donor into a person whose kidneys no longer work well. This procedure is often the preferred treatment for people with end-stage renal disease (ESRD), which is when the kidneys have lost most of their ability to filter waste from the blood. Common causes of kidney failure include long-term diabetes, high blood pressure, and certain genetic conditions.
For many people, a transplant offers a better quality of life and a longer life expectancy compared to staying on dialysis (a treatment that uses a machine to clean the blood). Your clinician may recommend starting the transplant process early, sometimes even before you need to start dialysis. This is often called a preemptive transplant, and it may help you avoid the complications of long-term kidney failure.
When it may not be the right option
A kidney transplant is a major surgery that requires a lifelong commitment to taking medications and attending follow-up appointments. Because of this, it may not be the safest or most effective choice for everyone. Your care team will perform a thorough evaluation to see if the benefits of the surgery outweigh the risks for your specific situation.
Your clinician may decide a transplant is not the right option if you have certain health conditions. These can include severe heart or lung disease, an active or recently treated cancer, or a serious infection that is not under control. Additionally, if a person has difficulty following a complex medical schedule, the care team may suggest other treatments to ensure the best possible health outcome.
Questions to ask your care team
Deciding on a kidney transplant is a big step. It is helpful to bring a list of questions to your appointments to help you and your family make an informed decision. You might consider asking:
- What are the specific benefits and risks of a transplant for my health?
- How long is the typical wait time for a kidney in our region?
- What is the difference between receiving a kidney from a living donor versus a deceased donor?
- What tests will I need to complete during the evaluation process?
- How will my daily life and medications change after the surgery?
The procedure & preparation
๐ฅ What happens during the procedure
In the procedure room
When you are taken into the operating room, you will meet your surgical team. This group usually includes transplant surgeons, specialized nurses, and an anesthesiologist (a doctor who manages your sleep and pain). The room is kept very clean and sterile to protect you from infection.
You will be helped onto a surgical table and positioned comfortably. The team will perform a final safety check to confirm all details before the procedure begins. You may feel a slight chill in the room, but the team will provide warm blankets to keep you comfortable.
High-level steps
The surgeon makes an incision (a surgical cut) in the lower part of one side of your abdomen. In most cases, your original kidneys are left in place unless they are causing specific problems like high blood pressure or infection. The new kidney is placed in the lower abdomen where it is well-protected.
The procedure involves three main connections:
- Blood Vessels: The surgeon connects the artery and vein of the new kidney to your own blood vessels so blood can flow through the new organ.
- Ureter: The ureter (the tube that carries urine) from the new kidney is connected to your bladder.
- Closing: Once the kidney is working and blood flow is stable, the surgeon closes the incision with stitches, staples, or surgical glue.
Anesthesia and pain control
You will receive general anesthesia, which is medicine that puts you into a deep sleep. This ensures you will not feel any pain or be aware of the surgery while it is happening. The medicine is typically given through an IV (a small tube in your vein).
As you wake up, you may feel some soreness or pressure at the site of the incision. Your clinician may use a combination of IV medications and oral pain relievers to keep you comfortable. It is common to feel groggy or sleepy for a few hours after the anesthesia wears off.
Monitoring and safety steps
Your safety is the top priority during the transplant. The team uses specialized monitors to track your heart rate, blood pressure, and the amount of oxygen in your blood every few minutes. This allows the anesthesiologist to adjust your medications instantly if needed.
The surgical team also monitors the new kidney as soon as it is connected. They check to see that blood is flowing properly and, in many cases, they can see the kidney begin to produce urine before the surgery is even finished. This monitoring continues closely as you move to the recovery area.
Immediately after the procedure
After the surgery, you will be moved to a recovery room or an intensive care unit where nurses will watch you closely. You will likely have a catheter (a thin, flexible tube) in your bladder to drain urine and help the team measure how well the new kidney is working. This is usually temporary and is removed after a few days.
You may also notice a small tube near your incision to drain any extra fluid, which helps reduce swelling. Most patients stay in the hospital for several days. During this time, your clinician may start you on medications to prevent your body from rejecting the new kidney.
Typical procedure length
A kidney transplant surgery typically takes about 3 to 4 hours. The exact time can vary based on your individual anatomy and medical history. Your surgical team will provide updates to your family or support person during the procedure to keep them informed of your progress.
๐ง Different approaches doctors may use
Common approaches (open vs minimally invasive)
The standard method for a kidney transplant is often referred to as "open" surgery. During this procedure, the surgeon makes an incision (cut) in the lower part of your abdomen. The new kidney is placed inside your body in the lower belly area, rather than in the back where your original kidneys are located. This location makes it easier for the surgeon to connect the new kidney to your blood vessels and bladder.
In some medical centers, surgeons may use a minimally invasive approach known as robotic-assisted kidney transplantation. This technique uses smaller incisions and robotic arms controlled by the surgeon to place the kidney. While this option can sometimes lead to smaller scars, it is not available at all hospitals and may not be suitable for every patient. Your transplant team will recommend the safest approach based on your specific anatomy and medical needs.
Partial vs total
Unlike some other organ surgeries, a kidney transplant does not usually involve removing your original organs. In most cases, your own kidneys are left in place. This means the procedure is not a "total" replacement of your anatomy, but rather the addition of a healthy, functioning organ. Leaving the original kidneys avoids the risks associated with extra surgical steps.
However, there are specific situations where a doctor may recommend removing one or both of your original kidneys (a procedure called a nephrectomy). This might be considered if the original kidneys are causing severe high blood pressure, chronic infections, or are greatly enlarged due to conditions like polycystic kidney disease. If removal is not necessary for your health, the standard approach is to leave them alone.
Revision or repeat procedures
If a transplanted kidney stops working well after a period of time, it is often possible to undergo a second or even third transplant. This is known as a re-transplant. The surgical process is similar to the first, but the surgeon may place the new kidney on the opposite side of your abdomen to avoid scar tissue from the previous surgery.
In some cases, a patient may need a revision surgery to fix a specific issue with an existing transplant rather than replacing it. For example, if there is a leak where the ureter (the tube carrying urine) connects to the bladder, or if a blood vessel narrows, a surgeon can perform a procedure to repair these connections. These interventions help protect the function of the transplanted kidney.
๐งช How to prepare
Tests and imaging that may be done
Before you can be placed on the waiting list or scheduled for surgery, you will go through a thorough evaluation. The transplant team needs to confirm that you are healthy enough for the operation and that your body is ready to accept a new kidney. This process involves several types of checks.
- Blood typing and tissue typing: These tests look at genetic markers in your blood. This helps the team find a donor kidney that is a good match for your body.
- Crossmatch: This is a specific blood test that mixes your blood with the donorโs blood. It checks to see if your immune system has antibodies that would reject the new kidney.
- Heart and lung exams: You may have an EKG, echocardiogram, or chest X-ray to ensure your heart and lungs are strong enough for surgery.
- Cancer and infection screening: Doctors will check to ensure you do not have active cancer or serious infections that could complicate the transplant.
- Psychological evaluation: You may meet with a social worker or counselor to discuss your emotional health and ensure you have a support system in place for recovery.
Medication adjustments
Your care team will review everything you take to ensure your safety during surgery. It is important to tell your doctor about all prescriptions, over-the-counter medicines, vitamins, and herbal supplements. Some supplements can increase the risk of bleeding or interact with anesthesia.
Your clinician may ask you to temporarily stop taking certain drugs, such as blood thinners (like aspirin or warfarin), in the days leading up to the procedure. If you are on dialysis, your team will also tell you when to schedule your last session before the operation. However, do not make changes on your own. Only stop medicines if your clinician instructs you to do so.
Day-before and day-of instructions
When the time comes for your transplant, things can move quickly. You will generally be instructed not to eat or drink anything (fasting) starting at midnight the night before the surgery. This is necessary to keep your stomach empty for anesthesia.
On the day of the surgery, the medical team will guide you through the final steps:
- Final checks: You will have a physical exam and final blood tests to confirm you are ready.
- IV placement: A nurse will place a small tube (IV) into a vein in your arm or hand to deliver fluids and medicine. You may receive a sedative to help you relax.
- Anesthesia: You will receive general anesthesia, which puts you into a deep sleep so you do not feel pain during the procedure.
- Catheter: A thin tube is usually placed into your bladder to drain urine. This helps the doctors measure how well the new kidney is working right away.

โ ๏ธ Risks & Possible Complications
General surgical risks
Like any major operation, kidney transplant surgery carries standard risks. These are not necessarily specific to the kidney itself but are associated with undergoing surgery and anesthesia. Your care team takes many steps to prevent these issues before they happen.
Possible general risks may include:
- Infection: This can occur at the site of the incision or in the lungs (pneumonia).
- Bleeding: Some patients may experience bleeding during or after the surgery.
- Blood clots: Clots can form in the legs or move to the lungs, which is why early movement after surgery is encouraged.
- Reaction to anesthesia: Some people may have a reaction to the medication used to put them to sleep during the procedure.
Procedure-specific complications
There are also risks directly related to the new kidney and how your body reacts to it. One of the most significant concerns is rejection. This happens when your bodyโs immune system sees the new kidney as foreign and tries to attack it. Taking anti-rejection medications (immunosuppressants) exactly as prescribed helps prevent this.
Other complications specific to kidney transplants may include:
- Medication side effects: Anti-rejection drugs can lower your immune system, making you more prone to infections. They may also increase the risk of conditions like high blood pressure, diabetes, or bone thinning.
- Ureteral issues: The tube that carries urine from the kidney to the bladder (the ureter) can sometimes leak or become blocked.
- Delayed graft function: Sometimes the new kidney is "sleepy" and does not start working immediately. You may need dialysis for a few days or weeks until it begins to function.
- Vascular problems: Rarely, there can be a blockage or narrowing in the blood vessels connecting the new kidney.
How complications are treated
Most complications are treatable, especially when caught early. Your transplant team will set up a strict schedule of follow-up appointments to monitor your health. They use blood tests and exams to check for signs of rejection or infection before you even feel symptoms.
Common treatments include:
- Adjusting medications: If you show signs of rejection, your doctor may change the type or dose of your anti-rejection medicine to stop the immune attack.
- Antibiotics or antivirals: Infections are treated with medication. Because your immune system is suppressed, your doctor may treat infections more aggressively than usual.
- Procedures for leaks or blockages: If there is a problem with the ureter or blood vessels, a doctor can often fix it with a minor procedure or surgery to repair the connection.
- Temporary support: If the kidney has delayed function, temporary dialysis keeps your body stable until the new kidney wakes up and takes over.
๐ Medications Commonly Used
Pain control medicines
After your surgery, it is normal to feel some discomfort while your body heals. Your clinician may use a variety of medicines to help manage this pain. This often starts with non-opioid options, such as acetaminophen, to keep you comfortable. In some cases, stronger pain relievers may be used for a short period under close supervision by your care team.
Your clinician will tailor your pain management plan to your specific needs. It is very important to tell your team about any known allergies or past experiences with pain medicine. They will also check for potential interactions with your other transplant medications to ensure your safety and protect your new kidney.
Antibiotics
Antibiotics are medicines used to prevent or treat infections caused by bacteria. Because a kidney transplant involves surgery and the use of medicines that suppress the immune system (the body's natural defense against germs), your clinician may prescribe antibiotics as a preventive measure. This helps protect you from infection while your body is recovering.
These medicines may be given through an IV (a small tube in your vein) or as pills. Your medical team will monitor you closely for any side effects and ensure the antibiotics do not interfere with your other treatments. Always let your team know if you have had a reaction to any antibiotics in the past.
Blood thinners and clot prevention
Blood thinners, also called anticoagulants, are often used to prevent blood clots from forming after surgery. Clots can be dangerous if they block blood flow to your new kidney or travel to your lungs or legs. Your clinician may use these medicines to help keep your blood flowing smoothly during the early recovery phase.
The use of blood thinners is carefully managed and monitored. Your clinician will tailor the type of medicine based on your health history and your specific risk factors. They will perform regular checks to make sure the medicine is working correctly and safely without causing excessive bleeding.
๐ When to Seek Medical Care After Surgery
Emergency warning signs
While serious complications are not common for everyone, certain symptoms require immediate attention to protect your health and your new kidney. You should call 911 or go to the nearest emergency room if you experience life-threatening symptoms.
Seek emergency care if you have:
- Chest pain or severe pressure
- Difficulty breathing or shortness of breath
- Uncontrolled bleeding from your incision
- Sudden, severe pain in your abdomen
Call your surgeon or clinic ifโฆ
Your transplant team needs to know about any changes in your health, especially signs that might suggest infection or rejection. Rejection occurs when your bodyโs immune system attacks the new kidney. This can often be treated successfully if caught early.
Contact your transplant coordinator or doctor right away if you notice:
- Fever: A temperature of 100.4ยฐF (38ยฐC) or higher, or flu-like symptoms such as chills and body aches.
- Changes in urine: A significant drop in the amount of urine you make, pain when urinating, or blood in your urine.
- Incision issues: Redness, warmth, swelling, or drainage (pus) at the surgery site.
- Fluid retention: Sudden weight gain (such as 2 to 4 pounds in a day) or swelling in your hands, feet, or eyelids.
- Pain: New or worsening tenderness directly over the new kidney.
Expected vs concerning symptoms
Recovering from surgery takes time, and it is helpful to know what is part of the normal healing process versus what requires medical help.
Pain and soreness
Expected: It is normal to feel soreness around the incision site for several weeks. Your care team will likely provide pain management options to help you stay comfortable.
Concerning: Severe pain that does not get better with medication, or sudden sharp pain near the transplant site, should be reported.
Digestive issues
Expected: You may have mild changes in appetite or digestion as you adjust to new medications.
Concerning: Persistent nausea, vomiting, or diarrhea can be dangerous because they may prevent your body from absorbing the anti-rejection medicines you need. If you cannot keep your pills down, call your clinic immediately.
๐ฎ Outcomes & Long-Term Outlook โญ
Alternatives & decisions
๐ Alternatives or Non-Surgical Options
Non-surgical treatments
The most common alternative to a kidney transplant is dialysis. This is a medical treatment that filters waste, extra salt, and water from your blood when your kidneys can no longer do the job. It helps keep your bodyโs chemicals in balance and manages blood pressure.
- Hemodialysis: This process uses a machine to filter your blood. It is usually done at a hospital or a dialysis center three times a week, though some people may be able to do it at home.
- Peritoneal dialysis: This method uses the lining of your own abdomen (belly) to filter your blood. A special cleaning fluid is put into your abdomen, left there to collect waste, and then drained out. This is often done daily at home.
Your clinician may also use medical management. This involves using specific medications and a strict diet to manage the symptoms of kidney disease. While these treatments help you feel better, they do not replace the function of the kidneys as effectively as a transplant or dialysis.
Watchful waiting
If your kidney disease is in the earlier stages, your care team may suggest "watchful waiting." This means they will monitor your condition closely through regular checkups rather than rushing into surgery or dialysis. This approach is common when your kidneys are still working well enough to keep you healthy.
During this time, your clinician will track your glomerular filtration rate (GFR). This is a standard test that measures how well your kidneys filter waste from your blood. You may also work with a dietitian to lower your intake of certain minerals and proteins to reduce the stress on your kidneys.
Watchful waiting allows you to maintain your current lifestyle while your medical team looks for signs that your condition is changing. If your lab results show a steady decline in function, your team will begin discussing the next steps for treatment.
When surgery becomes the best option
Surgery is usually considered the best option when a patient reaches end-stage renal disease (ESRD). This is when kidney function has dropped to about 15% or less of what is normal. At this stage, the kidneys can no longer keep up with the body's needs, and dialysis or a transplant becomes necessary to sustain life.
Your clinician may recommend a transplant because it often offers more freedom and a better quality of life than long-term dialysis. Many people find they have more energy and fewer diet restrictions after a successful transplant. Research also suggests that many patients may live longer with a transplant compared to those who stay on dialysis.
In some cases, your doctor might suggest a "preemptive transplant." This means having the surgery before you even need to start dialysis. This is often recommended because it may lead to better long-term health outcomes and avoids the physical stress that dialysis can sometimes cause over time.

โ Common Misconceptions
๐งพ Safety & medical evidence
Evidence overview
Kidney transplantation is widely considered the preferred treatment for many people with kidney failure. Medical research and long-term data suggest that, for eligible candidates, receiving a transplant often leads to a longer life and a better quality of life compared to remaining on lifetime dialysis.
Studies indicate that transplants from living donors generally start working faster and last longer than those from deceased donors. However, both options are standard medical procedures with well-documented success rates. Your transplant team relies on decades of clinical evidence to determine the best approach for your specific situation.
Safety notes and individualized care
Because a kidney transplant is a major surgery, it requires a thorough safety evaluation. Before being placed on the waiting list, you will undergo tests to check your heart, lungs, and immune system. This helps the medical team ensure your body is strong enough to handle the operation and the recovery process.
After the surgery, you will need to take anti-rejection medicines (immunosuppressants) for as long as you have the transplant. While these medicines are necessary to keep your body from attacking the new kidney, they can lower your immune systemโs ability to fight infections. Your care team will monitor you closely to balance these medications.
Common safety considerations include:
- Surgical risks: As with any major operation, there are risks of bleeding, infection, or reaction to anesthesia.
- Rejection monitoring: Regular blood tests help detect if your body is trying to reject the new kidney so doctors can adjust your treatment early.
- Long-term health: Your clinician will help you manage blood pressure and cholesterol to protect the new kidney.
