[Updated techniques of guidance in prostatic biopsy puncture].

Pathological results are a gold standard for the diagnosis of prostate cancer (PCa), one of the ways to obtain the pathological tissue is prostate biopsy. With the advances in detection technology, biochemical examination and medical imaging have greatly improved the detection rate of PCa. However, the final therapeutic option depends on pathological results, and therefore the precision of prostate biopsy and puncturing technique is highly required. Specific requirements include pinpoint positioning of the lesion and exact sampling of the positive tissue to reduce pain caused by unnecessary invalid punctures, accurate navigation for deep lesions to avoid damage to the urethra and bladder and reduce bleeding and other complications. Current development of medical imaging and artificial intelligence has significantly promoted biopsy puncture techniques. This review updates the application of image fusion and robotics in prostate biopsy.
