[Cavernotomy].

Corpus cavernosal dilatation in patients undergoing implantation of a penile prosthesis may occasionally be impossible to achieve with the Edgart dilator owing to sclerosis. For this reason, we have developed the cavernotome, a specially designed dilator that allows for easy dilatation of the corpus cavernosum. Its salient edges and grooves permit cutting through the sclerotic areas without difficulty. It is indispensable for placement of an anatomic penile prosthesis in these cases.
