Penile-brachial pressure index as a guide for the dosage of intracavernous injection of papaverine.

From October 1985 to June 1986 we have treated 82 impotent patients. We related their penis-brachial pressure index (PBPI) with the dosage of papaverine necessary to obtain a full erection as measured by tumistore. We describe the technique and the relationship between the PBPI and the dose of papaverine necessary for the erection; in this way PBPI should be used as guide for the dosage of intracavernous papaverine injection.
