Abstract

OBJECTIVES

To assess the effects of autonomic nerve damage on the basis of cavernous electrical changes.

METHODS

A study was carried out on the cavernous electrical activity in healthy volunteers (controls) and impotent patients after radical cystoprostatectomy using a specific electromyographical device, the 'SPACE-recorder 7500'.

RESULTS

A significant reduction in the amplitude of potentials was recorded after pharmacological stimulation in both the controls and impotent patients. The healthy controls showed amplitude values which were significantly higher than the impotent patients after radical cystectomy (715 +/- 141 vs. 381 +/- 227 microV, p < 0.01). After 'nerve-sparing' radical cystectomy with a mean amplitude similar to controls (500-700 microV), the patients showed rigid erections after injection of intracavernous drugs in a high percentage of cases.

CONCLUSION

In our experience, corpora cavernosa electromyography seems a reliable method which can directly point out damage in the cavernous smooth muscle and the penile autonomic nerves.

摘要

目的

基于海绵体电变化评估自主神经损伤的影响。

方法

使用特定的肌电图设备“SPACE记录仪7500”，对健康志愿者（对照组）和根治性膀胱前列腺切除术后的阳痿患者的海绵体电活动进行了研究。

结果

在对照组和阳痿患者中，药物刺激后记录到电位幅度显著降低。根治性膀胱切除术后，健康对照组的幅度值显著高于阳痿患者（715±141对381±227微伏，p<0.01）。在进行“保留神经”的根治性膀胱切除术后，平均幅度与对照组相似（500 - 700微伏），在高比例的病例中，患者在注射海绵体内药物后出现坚挺勃起。
