Background: The inflatable penile prosthesis (IPP) is typically the preferred implant for Peyronie’s disease (PD)
and malleable penile prostheses (MPPs) have been discouraged.
Aims: To evaluate the effectiveness and patient satisfaction of the MPP vs IPP in patients with PD.
Methods: Men with PD and erectile dysfunction who elected for penile implant surgery constituted the study
population. Preoperatively, demographic and comorbidity parameters were recorded. Curvature was measured
with a goniometer at maximum rigidity after intracavernosal injection of a vasoactive agent. Postoperatively,
overall satisfaction was measured at 3, 6, 12, and 24 months on 5-point Likert scale from 1 (dissatisfied) to 5
(very satisfied).
Results: 166 men with a mean age of 59 ± 10 years were analyzed. The mean preoperative curvature in the
entire cohort was 65 (range ¼ 30e130). 94% of patients with MPP had total resolution of their curvature at
the end of the operation, whereas 8 patients (6%) had residual curvature (25e40). In the IPP group 25 of 30
(83.3%) had a straight penis at the end of surgery, whereas 5 of 30 (16.7%) had residual curvature, with the
mean magnitude being 33 in the MPP group and 30 in the IPP group. 86% of all patients had diabetes. There
were no differences between the 2 implant groups in age, hemoglobin A1c, body mass index, or smoking status.
The mean patient satisfaction was 4.42 ± 0.70 (range ¼ 2e5) and there was no difference between the 2 groups.
The mean follow-up period was 23.4 months (range ¼ 6e29 months).
Conclusion: We found that the MPP is as effective as the IPP in curvature correction in patients with PD, with
similar patient satisfaction for the 2 groups. |
