Electrically stimulated gracilis sphincter (dynamic graciloplasty) for treatment of intrinsic sphincter deficiency: a pilot study on feasibility and side effects.

PURPOSE: The feasibility and side effects of electrically stimulated gracilis sphincter (dynamic graciloplasty) were studied in 7 patients with severe incontinence due to intrinsic sphincter deficiency.

MATERIALS AND

METHODS

The distal part of the gracilis muscle is wrapped around the bladder neck. Afterwards, 2 muscle electrodes and a programmable pulse stimulator are implanted. During a stimulation program the fatigable type 2 skeletal fibers are replaced by slow type 1 fibers, which are able to sustain a long lasting contraction.

RESULTS

Among the patients 3 are continent, 1 is partially continent and treatment failed in 3.

CONCLUSIONS

The results are encouraging. Dynamic graciloplasty may have a role in the treatment of intrinsic sphincter deficiency.
