Summary
Lumbar diseases can cause autonomic dysfunction, affecting both the bladder and lower limbs. Urodynamic tests and sympathetic skin responses revealed significant abnormalities in patients, indicating neurogenic bladder and impaired nerve function.
Area of Science:
- Neurology
- Urology
Context:
- Lumbar diseases, such as intervertebral disc herniation (IDH), spinal canal stenosis (SCS), and spondylolisthesis with spondylolysis, can impact autonomic nervous system function.
- Urinary dysfunction is a common but often overlooked symptom in patients with lumbar pathologies.
Purpose:
- To investigate the relationship between lumbar diseases and autonomic dysfunction affecting the urinary system and lower extremities.
- To evaluate urodynamic parameters and sympathetic skin responses (SSR) in patients with lumbar diseases.
Summary:
- Urodynamic examinations revealed that 80% of patients with lumbar diseases exhibited abnormalities indicative of an occult neurogenic bladder.
- Sympathetic skin responses (SSR) showed significantly lower mean and maximal amplitudes in patients with intervertebral disc herniation (IDH) compared to healthy controls (p < 0.01).
- Findings suggest that autonomic dysfunction, involving both parasympathetic (bladder) and sympathetic (lower extremities) pathways, is present in patients with lumbar diseases.
Impact:
- Highlights the prevalence of occult neurogenic bladder in lumbar disease patients.
- Underscores the utility of urodynamic testing and SSR in diagnosing autonomic dysfunction associated with lumbar conditions.
- Emphasizes the need for comprehensive assessment of autonomic function in managing patients with lumbar diseases.
