Current opinion: complications and troubleshooting of sacral neuromodulation.

The complications of sacral neuromodulation have been minimized as technology has improved. The main surgical complication remains to be surgical site infection. We review evidence-based suggestions and procedure-specific techniques that reduce the infection rate to less than 2%. In the past, surgical revision was reported as high as 40%. The current revision rate at Mayo Clinic Florida is 10%. The most common reason for surgical revision is either battery end-of-life or loss of effectiveness. We review the best practices of the procedure and a systematic approach to troubleshoot loss of effectiveness.
