Prostate biopsy techniques and indications: when, where, and how?

Area of Science:

• Urology
• Medical Imaging
• Oncology

Background:

• Transrectal ultrasound (TRUS)-guided prostate biopsy is a prevalent office-based procedure for urologists.
• Over 50 years, prostate biopsy techniques, indications, and pathology interpretation have significantly evolved.
• The shift from blind finger-guided biopsies to systematic TRUS-guided biopsies marks a major advancement.

Purpose of the Study:

• To review current techniques and indications for TRUS-guided prostate biopsy.
• To discuss the evolution of prostate biopsy practices over the last five decades.
• To highlight the diagnostic and staging utility of TRUS in modern urology.

Main Methods:

• Review of historical and current practices in transrectal ultrasound (TRUS)-guided prostate biopsy.
• Analysis of evolving indications for prostate biopsy, including digital rectal examination (DRE) and prostate-specific antigen (PSA) screening.
• Examination of pathologic interpretation and staging data derived from TRUS-guided biopsies.

Main Results:

• Prostate biopsy indications have shifted from digital rectal examination (DRE) findings to prostate-specific antigen (PSA) abnormalities.
• TRUS has transitioned from a simple needle-guidance tool to a source of significant diagnostic information.
• TRUS-guided biopsy is now a crucial tool for staging and diagnosis in urology.

Conclusions:

• TRUS-guided prostate biopsy techniques and indications have advanced considerably.
• Prostate-specific antigen (PSA) has become the primary driver for prostate biopsies.
• TRUS-guided biopsy is an indispensable diagnostic and staging modality for urologists.
