Abstract
|
|
|
To clarify the correlation between erotic and nocturnal erection and evaluate their diagnostic efficacy in impotence, a comparative study was done with audiovisual stimulation penogram (AVS-Penogram) and nocturnal penile erection monitoring
(NPFM:
Rigiscan(r)) in two hundred twenty two impotent patients. The compatibility ratios of the audiovisual stimulation penogram and nocturnal penile erection monitoring were 74.2% in Type I (normal findings) and 66.6% in Type IIA penogram(unresponsive
type)
The ratio of type IIB(fluctuation type) was 37.9%, much lower compared to that of Type I. Based on the final diagnosis, audiovisual stimulation penogram-only had high compatibility ratio with psychogenic origin for Type I (77.7%) and with organic
impotence for Type IIA(80%). Moreover combined audiovisual stimulation penogram and nocturnal penile erection monitoring had higher compatibility ratio (86.2%) than that of audiovisual stimulation penogram only analysis (77.7%) with psychogenic
impotence. Therefore, we suggest that audiovisual stimulation is an accurate method in Type I and Type IIA. Furthermore combined interpretation of audiovisual stimulation pengram and nocturnal penile erection monitoring may produce more precise
diagnosis, especilally in psychogenic impotence.
