The purpose of this study is to determine how many patients who have failed treatment with a sacral lead can achieve good results with a pudendal, patients satisfaction with the results of each lead, complication rates after pudendal lead placement, and how many patients have required reprogramming of their device with EMG testing( a more costly procedure).

Patient who have had implantation of an interstim.

Detailed Description:

InterStim is a bladder pacemaker device that has been in use for over 10 years for patients with voiding dysfunction. Although standard of care is to place the lead at the sacral nerve, in some patients a better response is obtained by placing the lead at the pudendal nerve.

Data will be collected from the subjects medical records and a questionnaire will be mailed one time to assess patients perception of improvement and treatment satisfaction after pudendal Interstim.
