Success and failure in penile prosthesis surgery: two cases highlighting the importance of psychosocial factors

Two cases, carefully selected from a longitudinal, prospective investigation of the relationship between psychosocial variables and postsurgical adjustment to a penile prosthesis implantation, were studied intensively. In both cases, the patient and sexual partner were assessed, presurgically, on a number of psychological, marital, and sexual functioning variables; their subsequent satisfaction with the prosthesis, and their psychological, marital, and sexual adjustment were measured at 6 and 12 months postsurgery. Despite many similarities in medical aspects of the surgery, for one couple a successful outcome was evidenced, whereas the other couple demonstrated a therapeutic failure despite the technical success of the surgery. Psychosocial differences between the couples were identified as they may relate to the discordant outcomes observed. Clinical implications of these results are discussed, as are the strengths and weaknesses of our methodological approach.
