Abstract

BACKGROUND:

Sacral nerve stimulation implies electrical stimulation of a sacral nerve root by an electrode and a pacemaker. Within the past few years, sacral nerve stimulation has become a possible treatment option for selected patients with urinary retention, urinary incontinence, anal incontinence and constipation. The method is furthermore being tested for several other conditions.

MATERIAL AND METHODS:

The article presents the method and treatment results following various indications based on the authors' own experience and non-systematic PubMed search.

RESULTS:

During a test period an external pacemaker is used for 3-30 days, with length of test differing according to the indication. A positive test (improvement of symptoms by 50 % or more) is achieved by 70-90 % of patients with anal incontinence, 70 % with urinary non-obstructive retention, 52-77 % with urinary urge incontinence and 43-72 % with constipation. Sacral nerve stimulation may also be effective in patients with chronic pelvic pain. Following implantation of a pacemaker a sustainable effect is seen in 50-90 % of patients with a positive test. Up to 75 % of patients will need repeated follow-up including pacemaker reprogramming or reoperations due to diminished effect. The longevity of the pacemaker is 3-10 years, and it must be replaced operatively when the battery has depleted.

INTERPRETATION:

Treatment with sacral nerve stimulation may be efficient over time in patients with various pelvic floor dysfunctions, especially anal incontinence and non-obstructive urinary retention. Most of the patients will need close follow-up in order to maintain an optimal result.
