B超用于检查前列腺大小时,一般需测出前列腺的左右径、前后径和上下径,再代入近似公式(如1979年Wichael报道4/3πr_1r_2r_3用的椭圆形公式算出前列腺体积)而得,由于其上下径的测定,需用体腔探测器经直肠或尿道探测,既不方便又不易被患者所接受,而一般医院又大多没有体腔探测器,为此我们通过26例开放性手术治疗前列腺增生症的病例,将术前B超测得的左右径和前后径与手术剜出的前列腺重量,应用直线回归方程计算,经统计学处理而得到利用两个径值推算前列腺重量的经验公式,并绘制诺模图。
B ultrasound used to check the size of the prostate, the prostate usually need to measure the left and right diameter, anteroposterior diameter and diameter, and then into the approximate formula (such as the 1979 Wichael reported 4 / 3πr_1r_2r_3 elliptical formula used to calculate the volume of the prostate) derived from The upper and lower diameter of the determination of the need to use the body cavity detector rectal or urethra detection is neither convenient nor easy to be accepted by the patients, and most hospitals and most of them have no body cavity detector, so we through 26 cases of open surgery for benign prostatic hyperplasia Of the cases, the preoperative B ultrasound measured left and right diameter and anteroposterior diameter and prostate surgery out of the weight of the prostate, using linear regression equation calculated by the statistical treatment of prostate diameter obtained by using two empirical formulas and draw Norm diagram.
