Transperineal prostate biopsy carries a significantly lower risk of infectious complications compared with the transrectal approach. We provide a step-by-step description of our current procedural technique for performing transperineal prostate biopsy under local anesthesia. A key component of our technique is the use of a disposable, probe-mounted needle guide that minimizes the number punctures to the perineal skin and allows for continuous needle visualization throughout the procedure. We have paired this device with a novel fusion biopsy platform that utilizes three-dimensional transrectal ultrasound to enable targeting of suspicious lesions found prebiopsy MRI as well as allows for mapping of biopsy core locations for postprocedure review and use at the time of subsequent prostate biopsy or ablation procedures.

手绘经会阴前列腺活检与三维超声器官跟踪。

与经直肠方法相比，经会阴前列腺活检的感染并发症风险显着降低。我们提供了我们目前在局部麻醉下进行经会阴前列腺活检的程序技术的分步说明。我们技术的一个关键组成部分是使用一次性的、探头安装的导针器，可最大限度地减少会阴皮肤的穿刺次数，并允许在整个手术过程中连续观察针头。我们将此设备与新型融合活检平台配对，该平台利用 3D 经直肠超声定位活检前 MRI 发现的可疑病变，并允许绘制活检核心位置以供术后检查和后续前列腺活检时使用或消融程序。
