The Albert Einstein hospital said the 74-year-old Pele remains in an intensive care unit undergoing "temporary" kidney treatment, but is "lucid" and breathing and eating normally without any support.
"Pele's clinical condition has been improving," the hospital said in its latest report.
Pele's personal adviser, Jose Fornos Rodrigues, confirmed Friday that Pele only has one kidney since the time he was a player, but said it was not affecting his treatment. Pele had surgery to remove the kidney back in the 1970s after complications from a broken rib.
The Brazilian soccer great had surgery to remove kidney stones on Nov. 13. He was readmitted to the hospital on Monday after being diagnosed with the urinary tract infection.

The hospital's press office would not say if Pele's condition was affected because he has only one kidney. The hospital said there was no sign of a widespread infection.
