Kidney transplant is the preferred option of treatment for patients with Chronic kidney disease,studies have shown poor outcome for obese patients BMI≥30kg/m2 and more perioperative complications,the aim of this study is to compare outcomes of obese patients BMI ≥30kg/m2 to patients with BMI<30kg/m2.


A retrospective single center cohort study of adult kidney transplant recipients between 1/2014 - 1/2016 compairing 308 patient BMI<30 to110 patients BMI≥30,one year patient and graft survival, incidence of delayed graft function, average hospital stay,wound and cardiac complications, new onset diabetes after transplant (NODAT),proteinuria and rejection .


Table1 shows obese patient with BMI≥30kg/m2 were older,diabetics,on peritoneal dialysis, had higher incidence of delayed graft function worse patient suvival in one year,other complcations were not significantly different among both groups


Kidney transplant recipients with BMI ≥30kg/m2 have higher incidence of mortality,delayed graft function than patients with BMI <30kg/m2.
Dietery counseling and referral for bariatric surgery is recommended for weight loss to improve post transplant outcome.
