Abstract

|
|
Objective: To investigate the immediate effect of dorsal penile nerve (DPN) stimulation on detrusor pressure (Pdet) and blood pressure (BP) during hyper-reflexic contractions of the bladder in patients with cervical spinal cord
injury
(SCI).
Method: The subjects were eight male patients with cervical SCI who had symptoms of autonomic dysreflexia. During water-cystometry, BP was monitored using an intra-arterial catheter into the radial artery, and was recorded simultaneously
with the
Pdet. Electrical stimulation was applied to the DPN, using surface electrodes each time a bladder contraction was detected. Baseline BP and BP at the first and the last hyper-reflexic contractions of bladder were measured with
Pdet, respectively.
Results: As Pdet increased, the BP increased in all cases. The reflex contractions of the bladder were effectively suppressed by DPN stimulation, and as the Pdet decreased during stimulation, radial arterial pressure
also
decreased immediately and significantly.
Conclusion: DPN stimulation can lower both Pdet and the elevated BP.
