Greetings
Transplant Surgery was newly established in April 2012, but kidney transplants have been performed at our hospital since 1976. The establishment of the Department of Transplant Surgery has enabled kidney transplant care to be performed under a more comprehensive system in collaboration with the Department of Nephrology Endocrinology and Metabolism .
Our departments work together to treat patients with various stages of kidney disease at the same 1st medical center, from those with early, mild chronic kidney disease to those who have developed chronic renal failure and are undergoing dialysis, and even those who have undergone kidney transplants. We also actively perform "preemptive kidney transplants," in which kidney transplants are performed before patients reach the stage of dialysis.
The future challenge for kidney transplants is how to maintain transplanted kidney function over the long term, and to achieve this, it is important to carefully manage complications such as hypertension, dyslipidemia, diabetes, and other so-called adult diseases. At our First Medical Center, in addition to Transplant Surgery, nephrology physicians and specialized nurses participate in the treatment of kidney transplant patients, striving to maintain transplanted kidney function over the long term.

Treatment details
Our department provides general surgical treatment for diseases specific to patients with chronic renal failure, focusing primarily on kidney transplants.
1) Kidney transplant
We collaborate with Department of Nephrology Endocrinology and Metabolism, also located within the First Medical Center, to provide kidney transplant surgery and follow-up care. There are three options for renal replacement therapy in the end-stage of chronic renal failure: hemodialysis, peritoneal dialysis, and kidney transplantation. Compared to dialysis, kidney transplantation restores lost kidney function and dramatically improves quality of life. Furthermore, it has been shown to improve the patient's life prognosis. Kidney transplant survival rates in Japan have been improving with each generation, currently standing at 97.8% (1 year) and 92.8% (5 years). In addition to providing pre- and post-kidney transplant care, we also offer transplant consultations and transplant nursing consultations in our outpatient clinics.
<Living donor kidney transplant>
Those who can donate a kidney are relatives (including spouses) who wish to donate a kidney of their own volition, and are called living kidney donors. Since one kidney is donated to a patient, the donor must not only have normal kidney function, but also be healthy, and various detailed tests are conducted to determine this. Living kidney transplants are possible even if the blood types are different. Living kidney transplants can be performed between relatives, including spouses, and relatives are defined as blood relatives within the sixth degree and in-laws within the third degree.
<Preemptive kidney transplant>
Preemptive kidney transplantation is a treatment method in which kidney transplantation is performed without dialysis when kidney function has declined due to chronic kidney disease. Our department works in cooperation with the Department of Nephrology and Metabolic Medicine, and has a policy of proactively performing preemptive kidney transplantation when conditions are met.
<Deceased donor kidney transplant>
This is a transplant in which a deceased person donates a kidney. There are two types of kidney transplants: cardiac death and brain death. If you wish to receive a kidney transplant, you must register with the Organ Transplant Network in advance.
2) Dialysis access (Arterio-venous shunt for hemodialysis, peritoneal dialysis catheter) surgery
A good dialysis shunt is necessary for better hemodialysis. We provide treatment and surgery for various complications related to dialysis shunts, such as shunt vascular stenosis and blockage, on an outpatient or inpatient basis. We also perform catheter-related surgery for peritoneal dialysis patients.
3) Surgical treatment for hyperparathyroidism
Nephrogenic secondary hyperparathyroidism is a serious complication for chronic dialysis patients, and surgery becomes necessary when medical treatment is no longer effective. For such patients, we perform parathyroidectomy. We work closely with the Department of Nephrology and Metabolic Medicine to properly manage the parathyroid function of dialysis patients. We also perform similar parathyroid surgery on patients other than dialysis patients.
4) Kidney transplant registration
We register patients who wish to be registered with the Japan Organ Transplant Network and provide follow-up care during the waiting period.
Main target diseases
-
Patients wishing to undergo a kidney transplant (consultations only are accepted)
-
Patients who wish to register for kidney transplantation
-
Dialysis access (dialysis shunt) stenosis and occulusion, etc.
-
hyperparathyroidism
Main medical achievements
Tokai University Hospital has performed more than 320 living donor and donor kidney transplants by 2023, regularly performing two living donor kidney transplants per month. Parathyroidectomies (2023): 13 (including primary) and dialysis access-related surgeries (2023): more than 250.
