[Dimensions, volume and rigidity of the penis. Fundamental elements in the study of the erection and its dysfunctions].

The length and the proximal and distal circumferences of the flaccid and erect penis were measured as part of the aetiological investigation of 62 impotent patients. These measurements, compared with the quantitative study of penile rigidity, demonstrate the lack of correlation between circumference changes and rigidity and constitute a simple method for the measurement of penile volume variations and, when compared with penile rigidity, provide important information concerning the physiology of erection and its dysfunction.

Intracavernous injection of papaverine as a diagnostic and therapeutic method in erectile failure.

The effect of intracavernous injection of papaverine (ICIP) has been investigated in 45 men: 6 normally potent volunteers, 10 psychogenic, and 29 organic impotent males. The first two groups obtained erections within 10 minutes, lasting from 1 to 4 hours, after injection of 80 mg of papaverine. Those belonging to the organic group experienced delayed, weaker and shorter erections, related to various degrees of arterial and/or venous and neurologic lesions. Haemodynamic and radiologic studies done concomitantly, showed a strong vasodilation in the penile arteries (even when pathologic) and a diminished outflow from the cavernous bodies. Subsequently, a pilot study was performed in a series of 63 patients suffering from various degrees of angiogenic impotence, in order to study the therapeutic effect of repeated intracavernous injections of papaverine completed by intracavernous infusion of heparinized saline. Erections improved significantly in 66% of the patients with a mean follow up of one year.

[Trial of intracavernous papaverine in the treatment of impotence. Therapeutic prospects].

The injection of 80 mg of Papaverine into one of the corpora cavernosa of the penis produces an erectile response which is proportional to the local haemodynamic conditions. On the basis of this test, the investigation of penile rigidity coupled with Doppler velocity studies permit cases of impotence due to vascular disease to be differentiated from other abnormalities of erection. The intensity of the response is proportional to the quality of the local vascular reaction. The intense vaso-dilatation of the cavernous arteries leads the author to propose the use of this drug and this route of administration in the treatment of certain cases of poor erection due to arterial disease.
