Kaplan-Meier curve of survival rate of developing upper UTS during the follow-up times between patients with UI and without UI for patients were not matched on metabolic syndrome (A) for patients were matched on metabolic syndrome (B), and for patients were matched on metabolic syndrome and X-ray examination (C).

<p>In both matching methods, the Log-rank tests show the survival rate of developing upper UTS during the follow-up times were significantly different between patients with and without UI (All p-values < 0.0001).</p
