ABSTRACT
Voiding functions in patients with non-neoplastic and non-traumatic myelopathy take a variable course according to severity and duration of disease. Fifteen patients of non-neoplastic and non-traumatic myelopathy were investigated neurologically thoroughly. On M.R.I. findings, hyperintense lesion was notified in a half of them but the others were nonspecific. On Pressure-Flow-EMG studies there were 7 cases of detrusor hyperreflexia with DSD, 2 cases of detrusor hyporeflexia with nonrelaxing striated muscle, 1 cases of detrusor hyporeflexia with coordinated striated muscle and 3 cases of normal findings. The thorough examination including M.R.I. and urodynamic study will be needed in patient with non-neoplastic and non-traumatic myelopathy because future possibility of their serious complications such as deterioration of renal function or impotence.
