Early problems encountered with the Mentor inflatable penile prosthesis.

R L Fein, M H Needell

    The Journal of Urology
    |July 1, 1985
    PubMed
    Summary

    The Mentor inflatable penile prosthesis shows promise but has drawbacks like slow deflation. Further research is needed to determine its long-term efficacy and compare it to other penile implant options.

    Area of Science:

    • Urology
    • Biomedical Engineering

    Background:

    • Penile prostheses are used to treat erectile dysfunction.
    • Previous inflatable penile prostheses, like the Scott system, have had documented issues.
    • The Mentor inflatable penile prosthesis represents a newer option for patients.

    Purpose of the Study:

    • To evaluate the outcomes and complications of the Mentor inflatable penile prosthesis in a series of patients.
    • To compare the performance of the Mentor system with prior experiences using the Scott inflatable penile prosthesis.

    Main Methods:

    • A consecutive series of 9 patients received the Mentor inflatable penile prosthesis.
    • Patient outcomes and complications were documented.
    • Comparison was made with previous experiences using the Scott inflatable penile prosthesis.

    Main Results:

    • Three of the 9 patients experienced successful outcomes.
    • Complications included spontaneous inflation, tubing kinks, aneurysmal ballooning, and cylinder disruption.
    • Slow deflation was identified as a potential inherent issue with the Mentor system, sometimes requiring penile squeezing which could lead to traumatic urethritis.
    • Concealment issues may arise without manual manipulation for deflation.

    Conclusions:

    • The Mentor inflatable penile prosthesis has potential but is not without complications.
    • Slow deflation and associated issues require careful consideration.
    • Interim use of a noninflatable prosthesis may be beneficial for managing a damaged corpus cavernosum.
    • Further long-term studies are necessary to fully evaluate the Mentor system's efficacy and compare it to historical devices like the Scott inflatable penile prostheses.
