Summary

Transrectal prostatic ultrasound can identify signs of prostatitis, including specific echo patterns and structural changes. While not diagnostic alone, these ultrasound findings aid in diagnosing chronic prostatitis and prostatodynia.

Area of Science:

  • Urology
  • Radiology
  • Medical Imaging

Background:

  • Prostatitis diagnosis is challenging due to varied symptoms and lack of physical signs.
  • Current diagnosis relies on identifying leukocytes in prostatic secretions via the Stamey localization procedure.
  • Transrectal prostatic ultrasound offers objective topographical data of the prostate.

Purpose of the Study:

  • To identify ultrasound features correlated with prostatitis diagnosis.
  • To evaluate the role of ultrasonography in assessing inflammatory prostate disease.
  • To correlate ultrasound findings with histological assessments and clinical diagnoses.

Main Methods:

  • Transrectal prostatic ultrasound was performed.
  • Seven specific ultrasound features were analyzed for correlation with prostatitis.
  • Ultrasound-guided biopsies enabled histologic assessment of parenchymal features.
  • Follow-up ultrasound studies monitored changes in echo-lucent zones.

Main Results:

  • Seven ultrasound features showed significant correlation with prostatitis: high-density/mid-range echoes, echo-lucent zones, capsular irregularity/thickening, ejaculatory duct echoes, and periurethral-zone irregularity.
  • Ultrasonography confirmed focal inflammatory disease, often in the peripheral zone.
  • Echo-lucent zones correlated with inflammation and could resolve with treatment, indicated by decreased leukocytes.
  • High-density echoes represent corpora amylacea; mid-range echoes, inflammation/fibrosis; echo-lucent zones, inflammation.
  • Low specificity and sensitivity of individual features preclude a single diagnostic criterion.

Conclusions:

  • The presence of multiple ultrasound signs suggests chronic prostatitis.
  • A normal ultrasound in symptomatic patients strongly indicates prostatodynia.
  • Echo-lucent zones may be useful for monitoring treatment response in prostatitis.
