title: [Preoperative volumetry of the prostate by transabdominal ultrasonography].
abstract: The transabdominal ultrasonography using a sector scanner, was useful to estimate the morphology of the prostate and to easily measure its width, depth and height, and the inferential volume of the prostate could be calculated preoperatively by the ellipsoid method. In the cases of good transurethral resection of prostate, the correlation (p less than 0.001) between the estimated and actual volumes, Y = 0.806X - 0.924 (r = 0.958), and that between the estimated volumes and the actual weights, Y = 0.973X - 2.175 (r = 0.981), were significant.
