简要总结
Prospective observational assessment of the efficacy of Spinal Cord Stimulation (SCS) treatment in patients with neuropathic pelvic pain.
详细描述
The objective of a clinical trial is an assessment of the efficacy of Spinal Cord Stimulation (SCS) treatment in patients with localized (not widespread pain), predominant neuropathic pelvic pain neuropathic pain (determined by PAIN-DETECT and rule out musculature pain).
Etiologies of CPP to be studied include but not limited to vulvodynia, perineal pain, perianal pain, bladder pain syndrome, and pelvic pain resulting from colorectal procedures. Medical review of the subjects will be done by a multidisciplinary team consisting of urologists/ gynecologists, interventional pain physicians, and psychiatrists.
Enrolled centers are National Hospital For Neurology and Neurosurgery in London in the United Kingdom, EuroPainClinics® with centers in Bratislava, Košice, and Bardejov in the Slovac republic and also EuroPainClinics® with centers Praha, Brno, Ostrava, and Hradec Kralove in the Czech republic.
Lead placement:
To be determined as a function of pain distribution. Lead placement will be either retrograde or anterograde determined by the investigator.

排除标准
- •Have a medical condition or pain in other area(s), not intended to be treated with SCS, that could interfere with study procedures, accurate pain reporting, and/or confound evaluation of study endpoints, as determined by the investigator (such as primary headache diagnosis or fibromyalgia).
- •Have a current diagnosis of a progressive neurological disease such a multiple sclerosis, chronic inflammatory demyelinating polyneuropathy, rapidly progressive arachnoiditis, brain or spinal cord tumor, central deafferentation syndrome, Complex regional Pain Syndrome, acute herniating disc, severe spinal stenosis and brachial plexus injury as determined by the investigator.
- •Have a current diagnosis or condition such as a coagulation disorder, bleeding diathesis, platelet dysfunction, progressive peripheral vascular disease or uncontrolled diabetes mellitus that presents excess risk for performing the procedure as determined clinically by the investigator.
- •Significant stenosis, objective evidence of epidural scarring and/or any signs or symptoms of myelopathy as determined by MRI conducted within the past 12 months.
