Evaluation of Targeted Biopsy Plus Sextant Biopsy in Diagnosis of Prostate Cancer

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.
