Summary

Negative pressure devices offer a successful solution for erectile dysfunction, even after penile prosthesis explantation due to complications like infection. This therapy can restore satisfactory erections and intercourse for many patients.

Area of Science:

  • Urology
  • Andrology
  • Medical Devices

Background:

  • Penile prosthesis implantation is a treatment for erectile dysfunction.
  • Complications such as infection, erosion, pain, or tissue necrosis necessitate prosthesis explantation.
  • Restoring erectile function after explantation presents a clinical challenge.

Purpose of the Study:

  • To evaluate the efficacy of negative pressure devices in restoring erectile function in patients who previously had penile prostheses explanted.
  • To assess patient satisfaction and success rates with negative pressure devices in this specific population.

Main Methods:

  • A prospective trial was conducted on 14 patients who had undergone penile prosthesis explantation.
  • Patients were offered a negative pressure device to attempt to restore potency.

  • Usage was monitored for at least 30 days of home use after initial demonstration.

    • Main Results:

    • 10 out of 11 patients (91%) who used the device at home reported satisfactory erections and successful intercourse.
    • 5 out of 6 patients explanted due to infection successfully used the negative pressure device.
    • Overall, 71% of the 14 explant patients achieved regular successful intercourse with the device.

    Conclusions:

    • Negative pressure devices are a viable and effective therapy for erectile impotence, particularly in patients with explanted penile prostheses.
    • This technology can provide a functional erection-like state even in cases with prior corporeal infection and fibrosis.
    • Negative pressure devices offer a valuable treatment option for a challenging patient group seeking to restore sexual function.
