To describe the development of screening tests and to identify re-operation rates after the permanent implant phase, and its characteristics, of the Interstim (Medtronic, Inc., Minneapolis, MI, USA) device for sacral nerve stimulation (SNS). ⋯ This study confirms the higher response rates of the tined-lead staged technique over PNE. Unobstructive urinary retention had the highest response rates. The reason for revision appeared to be largely predicted by the length of time since implantation.
