【摘要】 目的应用B超探讨输精管结扎术后前列腺增生症的发病率与年龄及结扎时间的关系。方法采用大量本群体抽样方法,调查了55岁以上男性1240例,其中结扎组850例,对照组390例,应用Aloka1400型B超仪,探头频率为3.5MHz,受检者在膀胱适度充盈下平卧位经腹部扫查前列腺体积(V)及残余尿(R)等指标分年龄段进行综合分析比较。结果结扎组各年龄段前列腺增生症的发病率均低于对照组。结论B超及综合临床各项检测项目认为输精管结扎可明显降低老年期前列腺增生症的发病率。更多还原

【Abstract】 Objective To study via ultrasound the relationship of the long-term incidence of the benign prostate hyperplasia(BPH)after vasectomy with the age and time of the operation.Methods Comparing and analyzing the data such as V and R in a survey of 1240 cases with an age range of more than 55 year’s old,the technique of random sampling was used.The experimental group contained 850 cases of vasoligation,who were accepted the operation more than 20 years ago,and 390 cases (control group) were not vasoligated.Both of them were examined by ultrasound Aloka 1400 with the probe of 3.5Mhz when their bladders were filled with urine properly.Results The incident rate of BPH in the experimental group was lower than that of the control group.Conclusions Vasoligation can obviously reduce the incident nate of BPH at old-age.更多还原
