Factors affecting outcome after percutaneous renal artery stent insertion.

Background: Renal artery stenosis is increasingly being treated with the percutaneous insertion of stents. Little data are available to help select patients most likely to derive benefit from the procedure.

Methods: Data were gathered on all patients treated with renal artery stent insertion at the Royal Melbourne Hospital prior to 1998, and who were followed-up for at least 6 months or until death.
