A preliminary evaluation of VISER testing in the diagnosis of ED / 中华泌尿外科杂志

ABSTRACT

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.
