The present study aims to investigate the role of bariatric surgery in improving transplant candidacy in patients prior to KTX, as well its safety and efficacy in KTX patients postoperatively.<h4>Methods</h4>A systematic search was conducted up to March 2020. Both comparative and non-comparative studies investigating the role of bariatric surgery before or after KTX were considered. Outcomes included change in BMI, rates of mortality and complications, and the rate of patients who underwent KTX following bariatric surgery. Pooled estimates were calculated using the random effects meCanadian Urological Association journal = Journal de l'Association des urologues du CanadaE553-E562https://www.ebi.ac.uk/biostudies/studies/S-EPMC8525519biostudies-literatureThe role of bariatric surgery on kidney transplantation: A systematic review and meta-analysis.PMC8525519Koyle MAFarcas MDoumouras AGLovrics OKhondker AHong DTian CLee YRaveendran LfalseThe role of bariatric surgery on kidney transplantation: A systematic review and meta-analysis.<h4>Introduction</h4>Obesity (body mass index [BMI] >35 kg/m²) remains a relative contraindication for kidney transplant, while patients after kidney transplantation (KTX) are predisposed to obesity.
