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 (NPEM: RigiScan) 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, audiovisua1 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 penogram is an accurate method in Type I and Type IIA. Furthermore combined interpretation of audiovisual stimulation penogram and nocturnal penile erection monitoring may produce more precise diagnosis, especially in psychogenic impotence.
