性功能障礙是脊髓損傷病患常見的後遺症,其中又以勃起障礙影響病患性生活活動最重要。勃起障礙引起之原因大概可分為三大類,即:心因性、神經性、血管性。脊髓損傷病患常因神經性勃起障礙,而影響他們的性生活,至於血管性勃起障礙則較罕見。本篇報告一脊髓損傷患者於十年前從橋上掉下受傷,並合併有勃起功能障礙。本科於三年前開始以前列腺素El做陰莖海綿體注射,針對脊髓損病患之勃起障礙做治療,且有顯著之成效。但唯獨此病患對前列腺素El做陰莖海綿體注射之反應不佳,卻對真空吸引器之治療有良好之反應,經陰莖血流檢查及陰莖海綿體造影檢查,證實病患是屬於血管性勃起障礙。對於脊髓損傷病患之勃起功能障礙的鑑別診斷是十分重要的,因為治療方法並不完全一樣,血管性勃起障礙患者,對於陰莖海綿體注射血管性藥物的反應並不理想。本篇並討論以前列腺素El做陰莖海綿體注射,在配合陰莖血流檢查,及陰莖海綿體造影檢查,對於勃起障礙之鑑別診斷有莫大的助益。
Sexual dysfunction Wth erectile disability is a common complication in spinal cord injured males. Usually their erectile dysfunction are neurogenic in originn. We have begun to apply intra-cavernous injection of prostaglandin E1(PGE1) for management of erectile dysfunction in spinal cord injuries since 1991 and encouraging results have been achieved. We report here a case of chronic spinal cord injury with vasogenic erectile dysfunction who does not respond to intracaver-nous PGE1 injection. We want to clarify that the use of intracavernous PGE1 injection in application to cavernosography and penile blood flow study is of great value in differential diagnosis of erectile dysfunction. Also the rehabilitation team shall keep in mind that vasogenic origin may be a cause of erectile dysfunction in spinal cord injured persons.
