A technique for transrectal ultrasonic volume determination of the prostate, based on the principle of serial planimetry, is presented. The preoperative ultrasonic determinations in 75 cases have been compared to the estimation of size by digital palpation and to the amount of tissue removed at operation. Scannings 6 to 10 weeks postoperatively have shown variable amounts of residual prostatic tissue. The difference in the preoperative and postoperative ultrasonic volume has been compared to the amount of tissue resected at operation, and the accuracy of the method has been established. The transrectal approach gives a close and complete view of the prostate, and has proved to be a simple, easily applicable and reliable method for volume determination. Postoperative scannings show morphological changes in the resection cavity, which are difficult to explain from scanning alone.
介绍了一种基于连续平面测量原理的经直肠超声测定前列腺体积的技术。对75例患者术前的超声测定结果与通过指诊估计的大小以及手术切除的组织量进行了比较。术后6至10周的扫描显示残留前列腺组织量各不相同。将术前和术后超声体积的差异与手术切除的组织量进行了比较，并确定了该方法的准确性。经直肠途径能对前列腺提供清晰完整的视野，已被证明是一种简单、易于应用且可靠的体积测定方法。术后扫描显示切除腔内有形态学变化，仅通过扫描难以解释这些变化。
