Cavernosography.

Corpus cavernosography of the penis is a valuable diagnostic technique in Peyronie disease, priapism, trauma, and especially in the evaluation of male impotence. Because it allows visualization of structural abnormalities within the cavernous tissues, it is particularly useful in the differential diagnosis of organic erectile failure. Normal anatomy of the penis and procedures for cavernosography are discussed, and seven cases are presented to illustrate some of the conditions in which cavernosography can provide anatomical and physiological information. Cavernosography was useful in establishing the diagnosis of organic erectile failure caused by structural abnormalities of the corpus cavernosa, and thus aided in the selection of appropriate therapeutic options.
