Lee Y, Anvari S, Chu MM, et al. - Improved renal function and BMI reduction may be conferred by bariatric surgery in chronic kidney disease (CKD) cases, and such patients may safely receive this procedure as a treatment option.

• Obesity may represent both a driver and comorbidity for CKD.

• Patients with at least stage 3 CKD and obesity undergoing bariatric surgery were analyzed.

• Systematic review and meta-analysis of 19 studies.

• Eligible studies were identified from Embase, MEDLINE, CENTRAL.

• Bariatric surgery resulted in improved eGFR with a mean difference (MD) of 11.64 mL/min/1.73m ² and decreased SCr with MD of −0.24 mg/dL following bariatric surgery.
