摘要
目的探讨前列腺增生程度的超声分级。方法对187例体检者采用经直肠前列腺超声检查。将端射式探头插入肛门,先暴露正中矢状切面,显示尿道内口,前列腺尿道近段、远段,精阜隆起等特征性结构,测量上下径及前后径;而后暴露斜冠状切面,显示移行区、尿道周围组织及其周缘区,观察内腺区(即移行区及尿道周围组织)回声情况,测量全腺区和内腺区最外缘之间的左右径及上下斜径,计算内腺左右径/全腺左右径,内腺上下斜径/全腺上下斜径,前列腺体积=π/6×上下径(cm)×左右径(cm)×前后径(cm)。结果187例受检者的前列腺内腺区回声情况可归纳为四种图像,在斜冠状切面显示最明显,相应地我们依据图像将前列腺增生分为0、、、这四个级别。在各级前列腺增生组所测参数中,部分前列腺参数(全腺的上下径、前后径、体积;内腺的左右径、上下斜径)在各组之间均>>>0,(P<0.01),内腺上下斜径/全腺上下斜径在各组之间为>,>0,(P<0.01),,之间P>0.05,差异不具有显著性,全腺的左右径在各组之间为>,,0,(P<0.01),0,,组之间P>0.05,差异不具有显著性。以上各组人群的年龄在各组之间为,>>0,(P<0.01),,之间P>0.05,差异不具有显著性。结论1.斜冠状切面是前列腺增生症分级诊断的最重要切面;2.前列腺各参数值对前列腺增生的分级诊断是有帮助的。
Objective To study prostate hyperplasia grading by ultrasonography. Methods Totally 187 examiners were checked by transreetal ultrasonography, the end-emission probe was inserted into anus, the mediam sagittal section was first exposed, the characteristic structures （internal opening, proximal segment and distal segment of urethra, projection of seminal eollieulus etc） were shown; the supenor and inferior diameters and anteroposterior diameters were measured and the oblique coronary section was exposed. The echoes of inner gland zone （including transmigration zone and urethral peripheral tissue） were observed; the left and right diameters, superior and inferior oblique diameters of entire gland were measured; the ratios of left and right diameters, superior and inferior oblique diameters between inner gland and entire gland and the volums of prostate [which equaled to π/6 × superior to inferior diameter （cm） × left and right diameter （cm） × anterposterior diameter （cm）] were eaeulated. Results The echoes of inner gland zones in 187 patients were classified into four kinds of images and the oblique coronary section was the most important section for hyperplastie grading. We relied on the images to sum up the prostate grading of hyperplasia as grade 0, Ⅰ , Ⅱ, Ⅲcorrespondingly, In total measured parameters of respective hyperplasia in prostate grading groups, part of them （superior and inferior diameters, anteroposterior diameters, volums of entire gland; left to right diameters, superior and inferior oblique diameters of inner gland ） were Ⅲ 〉Ⅱ 〉 Ⅰ〉0 （P〈0. 01）; the ratios of superior and inferior diameters between inner gland and entire gland were Ⅲ 〉 Ⅱ, Ⅰ〉0 （P〈0. 01） and there were no significant difference between groups Ⅱ , Ⅰ, P〉0. 05;the left and right bottom diameters of the entire gland were Ⅲ 〉0, Ⅰ, Ⅱ （P〈0. 01） in respective groups and there were no significant difference in groups 0, Ⅰ , Ⅱ, Ⅲ, P〉0. 05; the ages in above respective groups were Ⅲ , Ⅱ〉 Ⅰ〉0 （P〈0. 01） and there were no significant difference between group Ⅱ and Ⅲ. Conclusions 1. The oblique coronary section is the important section in diagnosing prostate hyperplasia grading. 2. The measurement of respective prostatic diameters is helpful in diagnosing prostate hyperplasia grading.
