Sacral nerve stimulation
Sacral Nerve Stimulation
Sacral nerve stimulation (pronunciation: SAK-rəl nərv stɪmjʊˈleɪʃən), also known as SNS, is a type of medical therapy that involves the use of electrical impulses to stimulate the sacral nerves located in the lower back. The term is derived from the Latin word "sacrum", which refers to the triangular bone at the base of the spine, and the English word "stimulation", which means to encourage something to happen or develop.
Overview
Sacral nerve stimulation is primarily used to treat urinary incontinence, fecal incontinence, and other pelvic floor disorders. The procedure involves the implantation of a small device, similar to a pacemaker, under the skin in the lower back. This device sends low-level electrical impulses to the sacral nerves, which control the muscles related to urinary and anal functions.
Procedure
The procedure for sacral nerve stimulation typically involves two stages: the test stimulation and the permanent implantation. During the test stimulation, a temporary wire is inserted under the skin and connected to an external device. If the test stimulation proves successful, a permanent device is then implanted.
Risks and Complications
As with any surgical procedure, sacral nerve stimulation carries potential risks and complications. These may include infection, device malfunction, and discomfort at the implant site. It's also possible that the stimulation may not effectively control symptoms.
