No I have not had renal angioplasty.
This is usually a safe procedure and the main complication is bruising around the site of the cannula insertion and as long as this does not become infected, it it no big deal. You know the signs of infection...I am sure.
Very occasionally there may be internal bleeding, but this is associated with abdominal pain.
He shouldn't be "crippled" with pain, but just keep an eye on the groin area for swelling pain to the touch associated with a feeling of malaise and general flu like symptoms and if they do occur, then contact the hospital again.
