In multivariate analysis, CKD was associated with a 63% increased risk UTUC, investigators reported in Medicine (Baltimore) (2016;95:e3255). The risk increased to 72% after excluding patients who progressed to dialysis and kidney transplantation. Results also showed that female gender was associated with a 38% increased UTUC risk.
