Area of Science:

  • Urology
  • Medical Imaging

Background:

  • Transrectal ultrasound is increasingly utilized for prostate evaluations.
  • Accurate staging of prostate cancer is crucial for effective treatment planning.

Purpose of the Study:

  • To compare the diagnostic efficacy of digital rectal examination and transrectal prostatic ultrasound.
  • To assess the impact of transrectal prostatic ultrasound on prostate cancer detection and clinical staging accuracy.

Main Methods:

  • A double-blind study involving 320 patients evaluated over two and a half years.
  • Comparison between digital rectal examination and transrectal prostatic ultrasound findings.

Main Results:

  • Prostate cancer was detected in 7.2% of patients (23/320).

  • Transrectal ultrasound identified cancers with both palpable (4.1%) and non-palpable (3.1%) nodules.
  • Clinical and pathologic staging correlated in 79% of detected prostate cancer cases.

    • Conclusions:

    • Transrectal prostatic ultrasound enhances the detection of prostate cancer, including non-palpable lesions.
    • The utilization of transrectal ultrasound significantly improves clinical staging accuracy for prostate cancer compared to digital rectal examination alone.
