Nitinol conical rugby embolus (NT-CRE) effectively treated varicocele in dogs and 10 human patients. This minimally invasive embolization technique showed no recurrence after 2.3 years, indicating a simple and effective varicocele therapy.

Area of Science:

  • Vascular Surgery
  • Interventional Radiology
  • Urology

Background:

  • Varicocele, a common cause of male infertility, often requires surgical intervention.
  • Existing treatments for varicocele have varying success rates and potential complications.

Purpose of the Study:

  • To evaluate the safety and efficacy of nitinol conical rugby embolus (NT-CRE) for varicocele embolization.

Main Methods:

  • Animal studies involving embolization of target veins in dogs with NT-CRE.
  • Pathological examination to assess NT-CRE impact and tissue response.
  • Clinical application of NT-CRE embolization in 10 patients diagnosed with varicocele.

Main Results:

  • Animal experiments demonstrated firm NT-CRE integration without misembolization and formation of fibrous tissue.

Related Experiment Videos

  • All 10 patients experienced complete resolution of varicocele and associated symptoms post-procedure.
  • Successful collapse of venae spermatica observed in treated patients.

    • Conclusions:

    • NT-CRE embolization is a safe and effective treatment for varicocele.
    • The procedure resulted in no recurrence of varicocele in patients during a 1.5-2.3 year follow-up period.
    • NT-CRE offers a simple and effective therapeutic option for varicocele management.
