Abstract:
Forty two patients including 1O cases of the normal control were studied with the radioisotope penogram. The causes of the impotence were arteriogenic in 1O cases, venogenic in 6, diabetes mellitus in 8, neurogenic in 2, endocrinogenic in 1 and psychogenic in 15, ranging from 19 to 70 years of age. Ten normal volunteers for the control group were ranged from 21 to 38 years of age. All were subjected to Snap-Gauge test and measurement of the penile blood pressure with estimation of the penile brachial index (P.B.I.). We calculated the Penogram Index in time-activity curve of the radioisotope penogram and studied the inter-relationship between the Penogram Index and the etiologic diseases, Snap-Gauge test, PBI. The results were obtained as follows; 1. Inter-relationship between the diseases and the penogram index, arterial index (Index A) and venous index (Index V1, V2); 1) Index A was 1.44 in normal control group, 0.55 in arteriogenic. 0.62 in venogenic, 0.64 in diabetes mellitus, 0.95 in neurogenic, l.29 in endocrinogenic and 1.03 in psychogenic impotence. This suggested that Index A was significantly correlative with state of the penile arterial inflow. 2) Index V1, V2 were 0.09, 90 in normal control group, 0.09, 51 in arteriogenic, 0.40, 29 in venogenic, O.8l, 38 in diabetes mellitus, 0.84, 90 in neurogenic, O.92, 34 in endocrinogenic, and 0.91, 64 in psychogenic impotence. This suggested that Index V1 and V2, particularly V1 was representative of maintenance of the penile blood flow and the penile venous outflow or leak. 2. Relation between Snap-Gauge test and Index A; Correlated in 77.8% of the patients and the normal controls, respectively. 3. Relation between P.B.I. and Index A; Correlative. 4. Relation between P.B.I and Index V1, V2; Not correlative Therefore, the radioisotope penogram was a very useful method in diagnosis of the organic impotence, particularly vasculogenic impotence to different late arteriogenic and venogenic.
