Where will the white matter lesion be positioned if you have urinary retention?
Urinary retention can be caused by demyelination anywhere between the upper brainstem and the lower spinal cord. However, urinary retention in isolation (without a lot of demyelination elsewhere) is usually caused by demyelination in the lower part of the spinal cord near the conus medullaris.
