In recent years, interstitial laser therapy was introduced to provide a new treatment of benign prostatic hyperplasia (BPH). However, the precise positioning of the laser fibers has remained a major unsettled issue. Three-dimensional (3-D) transrectal ultrasound scanning permits precise differentiation of the prostatic zones, in particular the transition zone, which is enlarged in BPH. Initially, a volume scan of the prostate is obtained. On the monitor, three sections of the prostate in the coronal, sagittal, and horizontal planes are displayed simultaneously. This new 3-D technology enables precise and reproducible positioning of the laser fibers at any selected site in the adenoma under sonographic guidance, thus providing the basis for complete laser prostatectomy. Placement of the laser fibers proved to be precise, quick, and uncomplicated.
近年来，间质激光疗法被引入用于提供一种治疗良性前列腺增生（BPH）的新方法。然而，激光纤维的精确定位仍然是一个主要的未解决问题。三维（3-D）经直肠超声扫描能够精确区分前列腺区域，尤其是在BPH中增大的移行区。最初，先获取前列腺的容积扫描图像。在监视器上，前列腺的冠状面、矢状面和水平面的三个切面会同时显示。这项新的3-D技术能够在超声引导下将激光纤维精确且可重复地定位在腺瘤内的任何选定部位，从而为完整的激光前列腺切除术提供了基础。事实证明，激光纤维的放置精确、快速且操作简单。
