Experience with Jonas malleable penile prosthesis.

Experience with the use of the Jonas penile prosthesis in 69 patients is presented, and the implantation of this prosthesis through a penoscrotal incision is described. Use of this prosthesis generally allows the penis to hang in a dependent position or to project outward from the body when coitus is desired. A malleable prosthesis such as the Jonas also has an additional advantage when it is used for treatment of impotence due to Peyronie disease, since its implantation allows the penis to be straightened without performing a simultaneous corporoplasty.
