Intravesical injection of onabotulinumtoxinA in neurogenic overactive bladder patients with human T-cell leukemia virus type 1-associated myelopathy: A single-institution case series.

Neurogenic overactive bladder is a main feature of human T-cell leukemia virus type 1-associated myelopathy/tropical spastic paraparesis. We successfully performed intravesical onabotulinumtoxinA therapy for refractory neurogenic overactive bladder due to human T-cell leukemia virus type 1-associated myelopathy/tropical spastic paraparesis.
