Abstract

Background: Sodium-glucose co-transporter 2 (SGLT2) inhibitors are novel anti-diabetic medications with potential beneficial effects on cardiovascular and renal outcomes, metabolic parameters and body weight. In addition to the beneficial effects on renal function, including estimated glomerular filtration rate and reduction in proteinuria, recent studies have investigated the potential role of SGLT2 inhibitor (SGLT2i) therapy on nephrolithiasis development. Nephrolithiasis, a condition affecting almost 10% of the general population at least once during a lifetime, is a common disorder with considerable risk for acute and chronic kidney injury and relatively few effective therapeutic options.

Methods: We performed a literature search through multiple databases, including PubMed, Ovid MEDLINE, Web of Science, Scopus and Cochrane Library. We followed the systematic review and meta-analysis guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. We included a total of 11 635 698 patients who experienced nephrolithiasis from six clinical trials in this meta-analysis study.

Results: In the pooled analysis, nephrolithiasis occurred in 1.27% of patients in the SGLT2i group (n = 739 197), compared with 1.56% of patients (n = 10 896 501) in the control arm (active control, placebo or no therapy). SGLT-2 inhibitor therapy has been associated with a lower risk for nephrolithiasis compared with placebo {odds ratio [OR] 0.61 [95% confidence interval (CI)…

How strong is the evidence?

Evidence Hub reads this as a meta-analysis, done in people. Its evidence level is 1 of 5 (Highest · pooled evidence). Pooled evidence from several studies sits at the top of the evidence pyramid. Reported size: 739 participants or records.
