ABSTRACT

To introduce the approaches and procedures of neurologic erectile dysfunction (ED ) assessm ent in our institute, and evaluate the neurologic investigation by m aking an analysis of 58 cases. D iagnostic criteria of neurologic ED nervous system injuries or diseases, abnorm al clinical sym ptom s and signs, electrophysiological abnorm alities of nervous system , abnorm al results of nocturnal penile tum escence and rigidity (N PTR ) (penis rigidity <60% and lasting tim e <10 m inutes). In the group of 20 patients w ith the injuries of the brain, spinal cord or spinal root nerves, pudendal cortical som atic evoked potential (PCSEP), sacral reflex latency (SRL),pudendal-to-corticalm otorevoked potential (PCM EP), penile sym-pathetic skin responses (PSSR ) and N PTR show ed abnorm ality by 45%, 20%, 20%, 85% and 85%, re-spectively. In 38 patients w ith the injuries of pelvic fracture w ith urethra break, PCSEP, SRL, PCM EP, PSSR and N PTR show ed abnorm ality by 24% , 5% , 20% , 92% and 66% , respectively. In the form er, 35% w ere identified to have severe ED , and 50%, m oderate ED;in the latter, 21%, to have severe ED , 13%, m edium ED , and 37%, light ED . The approaches and procedures w ere proved to possess excellent specificity and reliability in the assessm ent of neurological ED .
