Determination of the prostatic weight by suprapubic-transvesical ultrasonography was performed in 18 patients with benign prostatic hypertrophy. In all cases, the surgical capsule and the adenoma of the prostate were well visualized.
The weight of the whole prostate and the adenoma were computed using the formula of the ellipsoid object. And these calculated weights were compared with the actual weight of surgically removed adenoma.
There was a good correlation (r=0.943) between the sonometrically estimated weight of the whole prostate and the actual weight of the adenoma. However, the sonometrically estimated weights were 29.2±12.2 (Mean±S.D.) g greater than the actual weights.
On the other hand, there was a highly significant correlation between the adenomal weight determined by ultrasound and the postoperative weight of the adenoma. An average error of 9.5% and a correlation coefficiency of 0.973 were obtained.
