Fresh hyperplastic prostate glands from 19 patients who underwent open prostatectomy were weighed and their volume measured. After a simulated transurethral resection the weight and the volume of the pieces were determined. The volume of each enucleated specimen was plotted against the volume after electroresection. The regression coefficient was 0.8039. Similarly, the regression coefficient for the weight was 0.7864. Therefore a diminution in volume and weight of approximately 20% can be expected after electroresection. The specific weight close to one remained unchanged. The supracollicular distance was an unreliable indicator of the size of the prostate.
对19例接受开放性前列腺切除术患者的新鲜增生前列腺腺体进行称重并测量其体积。在模拟经尿道切除术后，测定切除组织块的重量和体积。将每个摘除标本的体积与电切后的体积进行绘图。回归系数为0.8039。同样，重量的回归系数为0.7864。因此，电切术后体积和重量预计会减少约20%。接近1的比重保持不变。视丘上距离不是前列腺大小的可靠指标。
