[Carvernosometry in impotence: method and standardization of normal values].

Cavernosometry and cavernosography in conjunction with artificial erection have been included in the protocol for the evaluation of sexual dysfunction in the male. The device is comprised of a volumetric infusion pump with a digital flow indicator, and the technique employed is bilateral puncture of the corpora cavernosa. Pressures are recorded by one needle while saline and contrast medium are introduced through the other. Eight males with no organic disorder were assessed for erection flow (EF) and maintenance flow (MF) to determine the normal and pathologic values for this method of evaluation. These values have a normal distribution. Calculation using formulas with a 99% reliability gave the following as pathological values: EF greater than 181 ml/min. or MF greater than 99 ml/min.
