The first domestic patient who had received implantation of a stimulator of anterior root of sacral nerve was followed up for 42 months.

No signs of sacral nerve root injury were found. In conclusion, stimulator of anterior root of sacralnerve (SARS) implantation is a safe and effective procedure and can be used in such patient for a long term. A test of the exterior parts of an indigenous stimulator shows that it is comparable to imported ones
