Summary

Managing prolonged priapism (erection lasting > 48 hours) significantly increases the risk of erectile dysfunction. Failure to achieve complete detumescence after treatment is the most critical factor impacting long-term sexual function in these patients.

Area of Science:

  • Urology
  • Andrology
  • Sexual Medicine

Background:

  • Priapism, a prolonged erection, can lead to significant complications including erectile dysfunction.
  • Understanding the long-term outcomes and risk factors associated with priapism management is crucial for patient care.

Purpose of the Study:

  • To evaluate the success rate of priapism treatments.
  • To assess post-treatment potency, complications, and risk factors for erectile dysfunction.
  • To analyze the impact of priapism duration and management strategies on long-term outcomes.

Main Methods:

  • Retrospective review of 50 patients diagnosed with priapism between 1981 and 1999.
  • Long-term follow-up (mean 66.4 months) of 35 patients assessing erectile function, recurrence, and complications.

  • Utilized Doppler ultrasonography and MRI to evaluate penile fibrosis and veno-occlusive incompetence in impotent patients.

    • Main Results:

    • 43% of patients reported preserved erectile function, more likely in those with brief priapism (< 48 hours).
    • Penile fibrosis was detected in 57% of patients, significantly more common in prolonged priapism (> 48 hours).
    • Failure to achieve complete detumescence after treatment was the most significant predictor of erectile dysfunction on multivariate analysis.

    Conclusions:

    • Low-flow priapism lasting over 48 hours, failure to achieve complete detumescence, and marked penile fibrosis are key risk factors for erectile dysfunction.
    • Complete detumescence after management is the most critical factor for preserving erectile function following priapism.
