The latest statement issued by the Royal Household Bureau on Saturday night said he was recovering from a respiratory infection in his left lung after being treated with antibiotics.
However it said he continues to receive renal replacement therapy, a treatment for acute kidney failure.
"Today he has no fever and his breathing is normal...a blood test showed that the infection has reduced but he still has a small amount of urine, therefore doctors continue to give him CRRT," the statement said, referring to continuous renal replacement therapy.
