The attacking midfielder faces a spell on the sidelines due to injury and has travelled to his native country for an operation
The 23-year-old has been troubled by his kneecap for some time and has now decided to travel to Rio de Janeiro this week for an operation which will be carried out by Brazilian national team doctor Jose Luiz Runco.
As a result, Leverkusen will have to make do without the player's services for the rest of 2011.
"The first half of the season is over for Renato. I understand that he will undergo surgery in Brazil and will probably stay there for two weeks and wait for his wounds to heal. Then his rehab will start with us," Dutt told Bild.
Augusto is the fifth Leverkusen player to undergo surgery in recent months, adding his name to list which already includes Rene Adler, Tranquillo Barnetta, Michael Ortega, and Bastian Oczipka.
