Sacral neuromodulation therapy for bladder and bowel control

Sacral Neuromodulation demonstrates positive results for Pelvic Floor Disorders. It is clinically shown to reduce dysfunctional voiding symptoms* in patients with urge incontinence, urgency-frequency, non-obstructive urinary retention, and chronic faecal incontinence, who have not been able to benefit from more conservative treatments.

Long-term control demonstrated at 5 years
Clinical studies evaluating Sacral Neuromodulation (SNM) for bladder control and bowel control have shown significant and lasting results.*(1,2)

Delivering significant improvements in quality of life

Study data demonstrates that patients who received SNM experienced significantly greater quality of life improvements compared with patients who received standard medical therapy.(1)

The only therapy that lets you test before you treat

You and your patient can find out in as few as 3-14 days whether Sacral Neuromodulation is likely to provide long-term control over symptoms.

Patient case examples

This therapy is not for everyone. Patient selection is important and not everyone who receives SNM will experience the same results as the patients presented below.
