Abstract:
This study is to compare the diagnostic usefulness and relationships between AVS penogram. Snap gauge test, and NPT monitoring in impotent patients confirmed using multidisciplinary diagnostic approach at the Department of Urology, Yonsei University College of Medicine from December 1986 to June 1987. Following results were obtained. 1. Among 24 cases of Group I(AVS penogram) 20 cases(83.3%) were psychogenic impotence, where 15 cases(75%) revealed sufficient penile rigidity on the Snap gauge test. 4 cases(16.7%) of group I were organic impotence, which revealed incomplete penile rigidity on the Snap gauge test. Among 45 cases of Group II-B(AVS Penogram) 34 cases(75.6%) were psychogenic impotence, where 28 cases(82.4%) showed sufficient penile rigidity on the Snap gauge test. 10 cases(24.4%) of Group II-B were organic impotence, which showed incomplete penile rigidity on the Snap gauge test. Among 17 cases of Group II-A and II-C 5 cases were psychogenic impotence, all of which revealed sufficient penile rigidity on the Snap gauge test. >From above results, the AVS Penogram is not a confirmative method, but using AVS Penogram and the Snap gauge test simultaneously will give useful information differentiating organic impotence and psychogenic impotence. 2. In comparison of AVS penogram and NPT monitoring, among 20 cases 7 cases of erectile curve showed similar shape, but the precise mechanism of each penile erection is not yet certain, more study is needed in the near future.
