Summary
Detrusor-sphincter dyssynergia (DSD) in brain bladder patients may indicate brainstem dysfunction. Dynamic CT scans and auditory brainstem responses suggest posterolateral pons involvement in DSD.
Area of Science:
- Neuroscience
- Urology
Context:
- Detrusor-sphincter dyssynergia (DSD) is a condition affecting bladder control.
- Brain bladder, resulting from neurological damage, can lead to DSD.
- Evaluating brainstem function is crucial for understanding DSD in these patients.
Purpose:
- To investigate brainstem function in patients with brain bladder and DSD.
- To correlate urodynamic findings with dynamic CT scan (DCT) and auditory brainstem response (ABR) results.
Summary:
- Urodynamic studies, DCT of the brainstem (focusing on the posterolateral pons), and ABR were performed on 13 brain disease patients and 5 controls.
- Abnormal DCT patterns (low peak value, prolonged filling, low clearance) were observed bilaterally in 4/6 DSD cases, versus none or unilateral in non-DSD cases.
- Prolonged interpeak latency (I-V IPL) in ABR was noted in DSD patients, with some showing ABR abnormalities precluding DCT analysis, suggesting posterolateral pons functional disturbance.
Impact:
- Findings suggest that DSD in brain bladder patients is associated with functional disturbances in the posterolateral pons.
- This study highlights the utility of neurophysiological and imaging techniques in diagnosing the underlying causes of bladder dysfunction.
