The 74-year-old was admitted to the Albert
Einstein Hospital in Sao Paolo on Tuesday for
the second time in six months.
Pele, the three-time World Cup winner, was
treated for a urinary infection in November 2014
after having kidney stones removed.
He was named Fifa's Player of the Century and
won 91 caps for Brazil, scoring 77 goals.
Widely regarded as the greatest player of all
time, he scored a world record 1,281 goals in
1,363 appearances during his 21-year career. He
was awarded the FIFA Golden Ball as the best
player at the 1970 tournament.
Pele has only one kidney, having had one
removed towards the end of his playing career
