    Many impotent men have normal penile arteries but venous leakage, identified by cavernosography. Papaverine injections helped reveal erection mechanisms, highlighting the importance of these diagnostic tools for impotence.

    Area of Science:

    • Urology
    • Andrology
    • Vascular Physiology

    Background:

    • Organic impotence often presents without arterial abnormalities.
    • The role of the venous system in erectile function requires further investigation.

    Purpose of the Study:

    • To determine the function of the penile venous system in erectile dysfunction.
    • To evaluate the active mechanisms of erection using papaverine.

    Main Methods:

    • Cavernosography performed on 187 impotent men with artificial erection induction.
    • Intracavernous pressure and inflow monitored during the procedure.
    • Papaverine injections administered to 69 patients to assess active erection mechanisms.

    Main Results:

    Related Experiment Videos

  • Venous leakage identified in 88 patients (47%).
  • Patients with venous leakage required higher flow rates for erection.
  • Papaverine administration decreased the flow rates needed to initiate and maintain erection.

    • Conclusions:

    • Cavernosography and cavernometry are crucial diagnostic tools for evaluating impotence.
    • Papaverine injections can aid in understanding the active mechanisms of erection.
    • Venous leakage is a significant factor in organic impotence for a subset of patients.
