Summary

This study shows that using an endovaginal ultrasound probe for prostate biopsies can improve cancer detection and staging. The technique offers better prostate sampling with minimal complications.

Area of Science:

  • Urology
  • Medical Imaging
  • Oncology

Background:

  • Sextant ultrasound-guided biopsy is the standard for prostate cancer diagnosis.
  • Modifications to this technique are continuously explored to improve accuracy.

Purpose of the Study:

  • To report the experience of using a 7.5 MHz endovaginal "end-fire" probe for prostate biopsies.
  • To evaluate its efficacy in diagnosing prostate cancer in patients with suspicious clinical findings.

Main Methods:

  • 262 ultrasound-guided transrectal 18G core biopsies were performed using the endovaginal probe.
  • Biopsy schemes were adapted based on ultrasound findings, including modified sextant biopsies and targeted cores from suspicious areas.

Main Results:

Related Experiment Videos

  • A prostate cancer detection rate of approximately 44% was achieved.
  • Complications were mild, with 1.9% urosepsis and 1.5% urinary retention. Hematuria and rectal bleeding were not significant.

    • Conclusions:

    • The endovaginal "end-fire" probe enables longitudinal and transverse core biopsies for optimal prostate sampling.
    • It facilitates safer transitional zone sampling, avoids the prostatic urethra, and improves peripheral zone access.
    • This technique allows accurate staging of prostate cancer prior to surgery.
