Early BOTOX After Spinal Cord Injury

Summary

The investigators would like to improve our understanding of how early intervention with the use of bladder chemodenervation can preserve bladder function in those with a new SCI. Although detrimental cystometric and tissue changes are known to occur, often within 3 months after SCI, the investigators seek to document the time course of these changes and the range of severity of those changes in both those participants that receive prophylactic treatment and those who do not.
