Urinary retention during sacral nerve stimulation for faecal incontinence: report of a case.

Sacral nerve stimulation (SNS) was proposed for the treatment of patients with urologic symptoms in 1967 but was not used until 1981. SNS has also proven to be a promising treatment in idiopathic faecal incontinence when conventional treatments have failed. The modality has been used for faecal incontinence since the mid-1990s. Eighty percent of the patients who were selected for percutaneous nerve evaluation (PNE) because of faecal incontinence report an improvement in the symptoms and qualify for a permanent implantation. Accordingly, SNS is now used for faecal incontinence and urologic symptoms. Reflex interactions between the bladder and the distal gastrointestinal tract are well known. The present case shows that SNS for faecal incontinence may significantly influence bladder function.
