[Preoperative estimate of the weight of prostatic adenoma using abdominal echography]

Using a sample of 41 patients, diagnosed with prostate adenoma, an estimate was made on the degree of correlation between the weight of the adenoma as predicted through abdominal ultrasound scan (x) and the actual weight after surgical removal (y). An experimental principle or mathematical formula has been worked out to translate that correlation and it allows the urologist to appraise the adenoma's actual weight as related to the ultrasound scan weight. The degree of correlation between the ultrasound-estimated weight and the actual weight was high (0.85) and statistically significant (p < 0.01). The experimental principle of mathematical formula which will allow the urologist to make a closer approximation to the actual weight of adenomas studied by ultrasound was y = 0.93 * x + 4.7.
