The correlation between the resected weight of prostate and the estimated weight of prostate by transrectal longitudinal ultrasound was evaluated for 53 patients with benign prostatic hypertrophy. Sonography was done with a real time linear scanner and 5.0MHz transducer. Maximal prostatic dimensions were measured along the two major axes, namely the maximal length and the maximal thickness of total prostate and adenoma. By regarding benign prostatic hypertrophy as an ellipsoid, we calculated the weight of prostate according to the ellipsoid formula. The correlation coefficient was calculated as; r=0.929, Y=0.942Xt-2.642 (Xt: total estimated weight), r=0.962, Y=0.965Xa+0.028 (Xa: estimated weight of adenoma). The estimated weight of the prostate correlated with the resected weight of the prostate.
These results suggested that rough estimation of the weight of benign prostatic hypertrophy was found to be possible by using this calculation technique.
