Summary

The goal of this randomized controlled trial (RCT) is to evaluate the efficacy and safety of different prostate biopsy schemes, including targeted biopsy plus sextant biopsy (3TB+6SB) and combination of targeted biopsy and 12-core systematic biopsy (3TB+12SB).

The main questions it aims to answer are:

Does 3TB+6SB promote the accurate diagnosis of clinically significant prostate cancer? What's the value of 3TB+6SB in improving the safety of prostate biopsy? Researchers will compare the cancer detection rates of 3TB+6SB and combination of 3TB+12SB to explore the efficacy of different prostate biopsy schemes. They will evaluate the safety profile of different prostate biopsy schemes through the complication rates and postoperative quality of life.

Participants will:

Receive 3TB+6SB or 3TB+12SB.

Conditions

Interventions

PROCEDURE

3TB+6SB

The biopsy procedure was conducted by a highly skilled and experienced urologist who specializes in performing prostate biopsies. Prophylactic antibiotics were routinely used both before and one day prior to scheduled surgery. Each patient was placed in the left lateral position or lithotomy position. The ultrasound equipment used included a color Doppler ultrasound diagnostic instrument (Hitachi HiVision, Philips Epiq 7), transrectal probes, and corresponding puncture needle guns. Color Doppler examination was performed from the base to the apex. For each predefined mpMRI suspicious lesion, urologists firstly obtained three-core TB from the lesion within the mpMRI suspicious lesion. Then urologists obtained sextant six-core SB. Each core was placed in an individual container and reported separately in accordance with the Ginsburg scheme. Histology was evaluated by senior uropathologists who were blinded to the imaging findings.
