Preliminary clinical report of treatment for neurogenic bladder by sacral neuromodulation using a new tined-lead electrode / 中国康复理论与实践

ABSTRACT

@#ObjectiveTo explore the effects of sacral neuromodulation using a new tined-lead electrode on neurogenic bladder.MethodsThe use of a new tined-lead electrode for sacral neuromodulation was evaluated in a study including 5 consecutive patients with neurogenic bladder.The tined leads were implanted at the S3 foramen under the X-ray screening.Subjects completed the recording of detailed voiding diary pre-and post-operation including fluid intake,voided volume,leaked volume,catheterized volume,frequency,accompanying symptoms and sensation.Vesicourethral function was assessed by video-urodynamics.ResultsUrinary frequency and voided volume were improved 22% and 49% respectively in one patient with spinal bifida.Urinary frequency,voided volume and residual volume were improved 0.7%,11% and 46% respectively in another one.Urinary frequency,voided volume and residual volume were improved 0.4%,18% and 44% respectively in the third one.Frequency of leakage and leaked volume were improved 36% and 54% respectively in the patient with brain trauma.Frequency of CIC and catheterized volume were improved 42% and 54% respectively,and indexes of urodynamics were improved 37%～45% in the patient with spinal cord injury.ConclusionA new tined-lead electrode for sacral neuromodulation provide a new alterative and minimally invasive procedure to treat neurogenic bladder.
