With the development of social economy and changes of lifestyle,obesity has become a very prominent social problem.Obesity and its-related metabolic diseases such as hypertension and diabetes can promote the occurrence and development of kidney disease,and eventually lead to end-stage renal disease..Kidney transplantation is the most effective treatment,but obesity increases the risk of surgical complications and poor outcomes.Hence obesity is considered a contraindication for kidney transplantation,as the benefits for obese patients are limited.Therefore,it becomes particularly important for obese patients to gain sufficient weight loss before kidney transplantation,which is not only related to whether transplant candidates are eligible for transplantation,but also the subsequent graft survival rate.Weight loss surgery can help obese patients achieve a significant amount of weight loss more quickly than traditional weight loss methods.In recent years,more and more scholars have applied bariatric surgery to the field of kidney transplantation.Research results have shown that bariatric surgery can improve the transplantation eligibility of kidney transplantation candidates with obesity,increase the survival rate of grafts and the lifetime of patients.Moreover,bariatric surgery can improve kidney function in patients with end-stage renal disease,thereby eliminating the need for kidney transplantation.At present,there is no any literature on the application of bariatric surgery in the field of kidney transplantation in China.This article reviews the current status and prospect of bariatric surgery in the field of kidney transplantation so as to provide reference for clinical practice.
