(NewsNation) — Pope Francis woke Monday morning and is resting after spending a 10th night at Gemelli Hospital in Rome, battling early signs of kidney failure, the Vatican said.

“The night went well; the Pope slept and is resting,” the Holy See Press Office said in a one-line statement Monday.

The 88-year-old pontiff was hospitalized for bronchitis Feb. 14 and subsequently treated for double pneumonia. He received blood transfusions and high levels of oxygen over the weekend and remains in “critical condition.”

This hospital stay is tied for the longest hospitalization of his papacy. In 2021, Francis spent 10 days at Gemelli Hospital for a partial colon removal, according to the Associated Press.

Doctors said their biggest concern now is the risk of germs that could enter his bloodstream and cause sepsis, a life-threatening infection. Medical staff said he will stay hospitalized at least through next weekend.
