- Abstract: PURPOSE: The clinical and urodynamic effects of intravesical capsaicin, a neurotoxic substance causing a reversible suppression of unmyelinated C fiber afferent neuronal activity, were investigated for treatment of detrusor hyperreflexia in patients with spinal cord injury. MATERIALS AND METHODS: Capsaicin solution (2mM) dissolved in 30% alcohol was instilled intravesically in 7 men with detrusor hyperreflexia due to spinal cord injury. Effects on bladder function and subjective symptoms were evaluated before and after intravesical instillation of capsaicin. RESULTS: Bladder function was improved in all but 1 patient. The improvement was expressed as an increase from 108ml to 270ml in maximal bladder capacity and a decrease from 75cmH2O to 44cmH2O in maximal detrusor pressure. Four patients had subjective improvement following treatment and the effects lasted for 4 to 6 weeks. Immediately after capsaicin instillation the ice water test was negative in 2 patients. Autonomic dysreflexia was observed in 4 patients, suprapubic discomfort in 3 patients and gross hematuria in 1 patient. CONCLUSION: Intravesical capsaicin seems to be a promising method for treatment of detrusor hyperreflexia, but the general use of intravesical capsaicin was limited due to side effects.
