Summary
Second line treatment for detrusor hyperreflexia is the intravesical BTX-A injections. First
300 units Botox are diluted with 30 ml of preservative-free saline. Using a rigid cystoscope
and an injection needle, BTX-A is injected into 30 sites within the detrusor muscle.
The used of KALINOX® (50% nitrous oxide and oxygen) inhalation has demonstrated analgesic
efficacy in various procedures (obstetric, liver biopsy, transrectal ultrasound guided
prostate biopsy, emergency) The aim of this study is to investigate the safety and efficacy
of analgesia with N2O/O2 inhalation for detrusor BTX-A injections using a rigid cystoscope.
