Objective: To investigate the immediate effect of dorsal penile nerve (DPN) stimulation on detrusor pressure (P-det) and blood pressure during hyperreflexic contractions of the bladder in patients with cervical spinal cord injury (SCI). Design: Blood pressure and P-det monitoring during cystometry with and without DPN stimulation. Setting: Urodynamic laboratory in a university hospital in Korea. Participants: Eight men (age range, 20-55y) with cervical SCI that was incurred from 4 months to 10 years before this study. Intervention: During water cystometry, blood pressure was monitored with an intra-arterial catheter introduced percutaneously into the radial artery and was recorded simultaneously with the P-det. Blood pressure was also measured manually with an electronic blood pressure cuff. Electric stimulation was applied to the DPN by using surface electrodes each time a bladder contraction was detected. Stimulation intensity was twice the threshold of the pudendal-anal reflex. Main Outcome Measures: P-det, systolic blood pressure, and diastolic blood pressure. Results: As P-det increased, the blood pressure increased in all cases. All the reflex contractions of the bladder were effectively suppressed by DPN stimulation. And as the P-det decreased during stimulation, radial arterial pressure also decreased immediately and significantly. Conclusions: DPN stimulation can decrease P-det and the increased blood pressure associated with it.
