The aim of the study was to determine the success rate, the complications,
the failures and the solutions found in troublesome cases. A retrospective
study was performed in three university centers in Belgium. Between March 1
994 and April 1998, a quadripolar electrode and a pulse generator were impl
anted in 53 patients (8 men, 45 women, 43 +/- 12 years, mean follow-up 24 /- 8 months, range 13-39 months). During the first few months, 45 (85%) of
the 53 patients had an objective response. Eight late failures occurred, wi
th a mean failure delay of 9 +/- 5 months. We performed 15 revisions in 12
patients. Major complications were pain and current-related troubles. The o
utcome was significantly better (P = 0.001) in poststress incontinence surg
ery patients. Device-related pain was found more frequently in patients wit
h dysuria and or retention or perineal pain, and the test stimulation was l
ess reliable (P = 0.025) in patients with a psychiatric history. Sacral ner
ve stimulation is efficient in treating patients with refractory lower urin
ary tract symptoms and/or perineal pain.
