Long-term follow-up data (median 11.7 years) are available from 111 patients that underwent sacral deafferentation and implantation with an anterior root stimulator. The maximum detrusor pressure during stimulation and during the storage phase both decreased significantly with time, with an increase in bladder compliance. However, none of these changes were found to be clinically relevant, indicating that sacral anterior root stimulation is a sustainable long-term intervention.
