Affordable novel device (VY) for transperineal prostate biopsy: A trial on prostate mannequin

Prostate cancer (PCa) is the most frequent malignancy in men worldwide after lung cancer. The gold standard for diagnosing prostate cancer is prostate biopsy. There are two main approaches for diagnosing PCa: transrectal biopsy and transperineal biopsy. In Indonesia, transperineal approach is rarely done as a part of diagnostic work up. The most known method of transperineal biopsy is the fan technique, which is a difficult technique to perform, particularly when directing the needle to the target accurately. For this reason, we develop an affordable bioplastic VY probe mounted needle guide device ($10) to provide precise needle insertion during the biopsy. In this study, we assessed the objective and subjective factors of the newly developed VY device. • Basic knowledge and operation technique were equalized by holding a prostate biopsy training using fan technique and VY device to 20 first-year Residents; • Participants were randomized and devided into two groups to perform fan technique and VY technique based on the training given; • Subjective factors (usefulness, the easiness, and preference) and objective factors (duration of puncture to needle visualization on USG, biopsy duration time, and the ability to reach the target tissue) were evaluated.
