The revised G.F.S. Mark II inflatable penile prosthesis shows no mechanical issues in 80 men. This implant allows for easy fluid adjustment, resolving previous connector and tubing problems.

Area of Science:

  • Urology
  • Medical Devices
  • Surgical Implants

Background:

  • The G.F.S. Mark II inflatable penile prosthesis has undergone revisions to address previous design flaws.
  • Connector and tubing issues were a known limitation in earlier versions of the device.

Purpose of the Study:

  • To evaluate the safety and efficacy of the revised connectorless G.F.S. Mark II inflatable penile prosthesis.
  • To assess the incidence of mechanical failures and the need for procedural adjustments post-implantation.

Main Methods:

  • Prospective study involving 80 male patients implanted with the G.F.S. Mark II inflatable penile prosthesis.
  • Follow-up period of up to 27 months to monitor device performance and patient outcomes.
  • Documentation of any mechanical problems, reservoir pump repositioning, or fluid additions.

Main Results:

  • No mechanical problems were reported with the G.F.S. Mark II inflatable penile prosthesis during the follow-up period.
  • Six patients required repositioning of the reservoir pump, and four required postoperative fluid addition.
  • The revised design successfully eliminated previous issues related to connectors and tubing.

Conclusions:

  • The connectorless G.F.S. Mark II inflatable penile prosthesis is a reliable device with no mechanical failures observed.
  • The integrated reservoir pump allows for convenient postoperative fluid adjustment as an office procedure.
  • This revised prosthesis offers an improved solution for patients requiring inflatable penile implants.
