The Argentine attacker is out of hospital and resting at home in Barcelona after undergoing a procedure that is aimed at solving his renal problems

Barcelona forward Lionel Messi is out of hospital and recovering after a non-surgical procedure to cure his kidney problems, Goal has learned.

The 28-year-old first suffered a renal complication back in December during the Club World Cup and missed Barca's semi-final win over Chinese champions Guangzhou Evergrande.

The five-times Ballon d'Or winner was in hospital in Barcelona on Tuesday for a lithotripsy, an extra-corporeal treatment that typically uses ultrasound shock waves to break kidney stones into small particles that can then be passed out by the body.

The procedure does not require incision but is usually carried out under a local anaesthetic because the shock waves can be painful.

Sources close to the player have confirmed to Goal that the procedure was planned after Barca announced further tests on Monday.
