For small prostatic nodules, ultrasound-guided biopsy is recommended. This helps differentiate benign conditions from cancer in peripheral prostate lesions, improving diagnostic accuracy.

Area of Science:

  • Urology
  • Diagnostic Imaging
  • Oncology

Background:

  • Prostate cancer diagnosis often relies on detecting suspicious lesions.
  • Small prostatic lesions (< 2 cm) present diagnostic challenges.
  • Distinguishing benign prostatic hyperplasia from malignancy is crucial.

Purpose of the Study:

  • To evaluate the diagnostic yield of ultrasound-guided transperineal biopsy for small prostatic lesions.
  • To determine the characteristics of benign versus malignant peripheral prostate nodules.
  • To assess the utility of ultrasonography in localizing suspicious prostate findings.

Main Methods:

  • A prospective study followed 63 patients with prostatic lesions ≤ 2 cm over 20 months.
  • Lesions were detected via palpation or ultrasonography (US).

  • All patients underwent US-guided transperineal biopsy for diagnosis.

    • Main Results:

    • Peripheral prostate nodules contained focal cancer, chronic prostatitis, or benign atypical hyperplasia.
    • No typical echo patterns differentiated these conditions within peripheral nodules.
    • Nodules in the periurethral gland were consistently benign hyperplasia.

    Conclusions:

    • US-guided biopsy is recommended for small, suspicious peripheral prostate nodules.
    • Biopsy is essential for accurate diagnosis of peripheral prostate lesions.
    • Ultrasonography effectively guides biopsy but lacks specific echo patterns for peripheral nodules.
