Vatican officials announced on Sunday that Pope Francis is currently suffering from "mild renal insufficiency" amid his treatment for bilateral pneumonia.

Pope Francis remains in critical condition, with blood tests showing mild signs of kidney failure “which is currently under control,” the Vatican said Sunday, as the 88-year-old pontiff battles pneumonia in both his lungs.

Francis remains in critical condition but has not suffered any additional crises, the Vatican said Sunday evening, after reporting Saturday the pope suffered a “long asthmatic respiratory crisis” days after he was hospitalized for pneumonia.
