Postimplant epididymitis is a rare complication after prostate brachytherapy, affecting 1% of patients. Higher preimplant American Urological Association (AUA) scores may indicate a risk for retrograde infection.

Area of Science:

  • Urology
  • Oncology
  • Medical Physics

Background:

  • Prostate brachytherapy using iodine-125 or palladium-103 is a common treatment for localized prostate cancer.
  • Postimplant complications can affect patient outcomes and quality of life.
  • Epididymitis, an inflammation of the epididymis, is a potential, though uncommon, complication following prostate brachytherapy.

Observation:

  • This study analyzed 517 patients undergoing prostate brachytherapy, identifying 5 cases (1%) of clinically diagnosed postimplant epididymitis.
  • The onset of epididymitis symptoms varied, appearing between 4 and 300 days post-implantation.
  • No significant associations were found between epididymitis and prostate volume, implant-related swelling, or seed count.

Findings:

  • Patients who developed epididymitis did not have a history of orchitis, epididymitis, vasectomy, or preimplant catheterization.

  • A higher preimplant American Urological Association (AUA) score was the only identified predictor for epididymitis, though 2 patients had low scores.
  • The incidence of epididymitis was lower in patients receiving perioperative antibiotics (0.4%) compared to those receiving prophylactic antibiotics (1.5%).

    • Implications:

    • Epididymitis is an infrequent complication of prostate brachytherapy, occurring in approximately 1% of patients.
    • Elevated preimplant AUA scores suggest a potential retrograde infection pathway contributing to postimplant epididymitis in some cases.
    • Further research may explore antibiotic prophylaxis strategies to mitigate the risk of postimplant epididymitis.
