Ra. Janknegt et al., ELECTRICALLY STIMULATED GRACILIS SPHINCTER (DYNAMIC GRACILOPLASTY) FOR TREATMENT OF INTRINSIC SPHINCTER DEFICIENCY - A PILOT-STUDY ON FEASIBILITY AND SIDE-EFFECTS, The Journal of urology, 154(5), 1995, pp. 1830-1833
Purpose: The feasibility and side effects of electrically stimulated g
racilis sphincter (dynamic graciloplasty) were studied in 7 patients w
ith severe incontinence due to intrinsic sphincter deficiency. Materia
ls and Methods: The distal part of the gracilis muscle is wrapped arou
nd the bladder neck. Afterwards, 2 muscle electrodes and a programmabl
e pulse stimulator are implanted. During a stimulation program the fat
igable type 2 skeletal fibers are replaced by slow type 1 fibers, whic
h are able to sustain a long lasting contraction. Results: Among the p
atients 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.
