Summary
Semirigid penile prostheses (SRPPs) result in significantly colder penile glans temperatures compared to normal erectile function, erectile dysfunction (ED), and inflatable penile prostheses (IPPs). Trimix injection significantly increased penile temperature.
Area of Science:
- Urology
- Andrology
- Therapeutic Devices
Background:
- Penile prosthesis implantation is a treatment for erectile dysfunction (ED).
- Understanding the thermal characteristics of the penis is important for evaluating penile health and prosthesis function.
- Cutaneous temperature can reflect underlying physiological changes.
Purpose of the Study:
- To compare penile cutaneous temperature across different groups: normal erectile function, ED, semirigid penile prostheses (SRPPs), inflatable penile prostheses (IPPs), and post-trimix injection.
- To investigate if SRPPs are associated with altered penile thermal profiles.
Main Methods:
- A total of 68 patients were evaluated across five groups.
- Penile cutaneous temperature measurements were taken.
- Comparison was made between groups and before/after trimix injection.
Main Results:
- Trimix injection significantly increased glans temperature by over 2.2°C compared to all other groups (P<0.001).
- Patients with SRPPs exhibited significantly lower glans temperatures than normal (P<0.02), ED (P<0.04), and deflated IPP (P<0.01) groups.
- The mean temperature difference for SRPPs was 1.44±0.40°C.
Conclusions:
- Men with SRPPs have a colder glans compared to men with normal erectile function, ED, IPPs, and post-trimix injection.
- Normal erectile function, ED, and IPP groups did not show significant differences in penile cutaneous temperature.
