Abstract

Penile sympathic skin response (PSSR) was measured in 20 normal patients and in 46 patients with erectile dysfunction (ED). PSSR could be registered in 80% of normal patients. The latencies were 1,100-1,600 ms. In patients with ED, latencies were 1,240-3,640 ms. A reproducible normal latency of PSSR (< 1,600 ms) indicates a normal sympathic innervation of the penis. Long latencies (> 1,800 ms) indicate neuropathy of unmyelinated nerval fibers. The loss of a reproducible answer however allows no exact diagnostic information. PSSR is a useful diagnostic test for detecting neuropathy of unmyelinated nerval fibers as a possible cause of ED.

摘要

对20名正常患者和46名勃起功能障碍（ED）患者进行了阴茎交感神经皮肤反应（PSSR）测量。80%的正常患者可记录到PSSR。潜伏期为1100 - 1600毫秒。ED患者的潜伏期为1240 - 3640毫秒。PSSR潜伏期可重复正常（<1600毫秒）表明阴茎交感神经支配正常。潜伏期延长（>1800毫秒）表明无髓神经纤维神经病变。然而，无法得到可重复的反应则无法提供确切的诊断信息。PSSR是一种用于检测无髓神经纤维神经病变作为ED可能病因的有用诊断测试。
