无创性动态阴茎海绵体测压的临床应用

A preliminary evaluation of VISER testing in the diagnosis of ED

目的 初步评价应用VISER软件行无创性动态阴茎海绵体测压在阳萎 (ED)诊断中的作用。 方法 采用AquariusXLT型尿动力学仪配置的VISER软件 ,辅助眼镜式影像仪听觉视觉性刺激 (AVSS)或阴茎海绵体内血管活性药物注射 (ICI)进行无创性动态海绵体测压 39例 ,其中ED患者 32例 ,正常对照 7例。 结果 正常对照 7例均可通过AVSS诱发勃起 ;32例ED患者中 ,13例单纯AVSS可诱发勃起 ,占 4 0 % ;19例单纯AVSS无效者 ,给予罂粟碱 10mg海绵体内注射 ,其中 13例出现勃起 ,占 6 8%。结果除ED罂粟碱组勃起平均时间延长外 ,勃起数据和峰值数据中的其他多项指标ED各组均低于对照组 ,尤以勃起和峰值总能量降低明显。 结论 VISER具有精确的动态阴茎海绵体测压功能 ;辅助眼镜式影像仪有助于增强AVSS效果和减少阴茎海绵体血管活性药物注射剂量 ;VISER检查具有无创、准确、便捷等优点 。

Objective To evaluate VISER as a non invasive monitoring of penile cavernosal pressure for the diagnosis of ED. Methods With the use of AVSS and papaverine ICI,39 cases,including 32 patients of ED and 7 controls,were tested with VISER device. Results 7 controls and 13 ED cases (40%) have achieved a valid erection by AVSS alone while another 13 ED cases required papaverine ICI (10 mg) for successful erection whereas 6 of ED cases failed what so ever. The VISER testing showed the erection data and peak data indexes, especially in total energy of erection and peak, were higher in controls than ED groups except the average duration of erection being longer in ED papaverine group. Conclusions VISER is an accurate system for measuring the changes of intracavernosal pressure in dynamic state during penile tumescence. The use of eye glasses TV monitor can help enhance the effectiveness of AVSS and lower the dosage of vasoactive drugs.VISER testing is non invasive,accurate and easy to perform and might serve as a screening test for ED patients in the near future.
