Comparison of the patient’s satisfaction underwent penile prosthesis; Malleable versus Ambicor: Single center experience

Objective: To compare the surgical results, complications, and satisfaction levels of patients who underwent malleable penile prosthesis implantation (M-PPI) and Ambicor penile prosthesis implantation (A-PPI).
Material and methods: One hundred forty two patients who underwent penile prosthesis implantation [M-PPI (Promedon- Tube®, Cordoba, Argentina): 81, and A-PPI (American Medical Systems, Minnesota, USA): 61] between 2013-2018 were evaluated retrospectively. Patients’ age, body mass index, smoking history, etiological factors, modified “Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS) Questionnaire” scores, shortening of the penis, and complications were recorded.
Results: The patients who performed A-PPI implantation were younger (56.27 ± 10.81 vs. 51.47 ± 11.79, p = 0.009). The EDITS scores of 31(38.2%) patients who underwent M-PPI and 44 (72.4%) patients who underwent A-PPI were available. It was observed that the scores on the following questions were statistical significantly higher in the A-PPI group: “Overall, are you satisfied with your penile prosthesis?, How much of your expectations did penile prosthesis meet?, How often do you use your penile prosthesis?” (p = 0.05, p = 0.048, p = 0.038). No difference was observed between the groups in terms of the scores on the other three questions (p = 0.447, p = 0.326, p = 0.365). A 61.3% of patients in MPPI (19/31) group, and 56.8% of patients in A-PPI (25/44) group stated penile shortening (p = 0.417). Mean shortening was reported as 2.1 ± 0.45 cm, and 2.12 ± 0.52 cm, in M-PPI and A-PPI groups, respectively (p = 0.90).
Conclusion:It is remarkable that the patients who underwent A-PPI experienced higher satisfaction with their prosthesis. Even though it has not been evidenced in the current literature data, patients who have had either M-PPI or A-PPI should be informed about the risk of penile shortening.
