Efficacy of Electrical Pudendal Nerve Stimulation for Neurogenic Lower Urinary Tract Dysfunction

Efficacy of Electrical Pudendal Nerve Stimulation for Neurogenic Lower Urinary Tract Dysfunction

The main goal to treat early NLUTS is to relieve lower urinary tract syndrome and prevent from late complications. The present study is to evaluate the efficacy of electrical pudendal nerve stimulation (EPNS) and transanal/transvaginal electrical stimulation (TES) in NLUTD.The study design consists of a non-randomized, parallel controlled trial. A total of 60 eligible patients will be involved and divided into EPNS or TES group according to their location of medical treatment. The primary endpoint is lower urinary tract syndromes (ICIQ-FLUTS/MLUTS). The second endpoint is assessment of daily life Qol (ICIQ-LUTSqol), and residual urine volume.

Inclusion Criteria:

• Age 18+ years;
• Diagnosed as NLUTD;
• Incomplete spinal cord injury (SCI), including but not limited to conus medullaris syndrome, cauda equina syndrome, etc.;
• Radical pelvic surgery: including but not limited to total hysterectomy etc.;
• Informed consent signed.

Exclusion Criteria:

• Anatomical bladder outlet obstruction (e.g., prostate enlargement, tumors);
• NLUTD induced by stroke, multiple sclerosis, HIV, diabetes mellitus, drug, and inflammation or tumor of central nervous system etc.;
• Lower urinary tract infections;
• Unwillingness to participate.
