【摘要】 目的,探讨应用超声观察男性输精管结扎后远期前列腺增生症(BPH)的发生率与年龄及结扎时间的关系。方法采用大样本群体抽样方法,调查了55岁以上男性1 240例,其中男扎者850例(结扎组),结扎时间距今已20年以上,未做男扎者390例(对照组),对其直肠指诊(DRE)、前列腺体积(V)等指标分年龄段进行了综合分析与比较。结果结扎组各年龄段BPH的发生率均低于对照组,而年龄在70岁以上(发生率为10．8％)、结扎时间在25年以上者发生率较低(为7．8％),两者比较BPH发生率差异具有显著意义。结论输精管结扎可明显降低老年期BPH的发生率。更多还原

【Abstract】 Objective To study relationship of the long-term incidence rate of benign prostate hyperplasia( BPH) after vasectomy to age and time after operation using ultrasonography. Methods Questionnaire survey, physical examination, and ultrasonography were conducted among 850 healthy males selected by randomized cluster sampling. The data such as international prostate symptom scoring (IPSS) .digital rectal examination (ORE), volume of prostate gland(V) were analyzed.Results The general BPH incidence rate of the vasectomy group was 10.8% m,significantly lower than that of the control group(40.8% ,P<0.01) .The age-specific BPH incidence rates in the vasectomy group were all significantly lower than those of the control group, especially that of the subjects aged over 70( 10.8 vs 56.5% ,P< 0.001).The volumes of prostate gland in all age subgroups were significantly smaller in the vasectomy group than those in the control group.Conclusion Vasectomy can reduce the incidence rate of BPH significantly.更多还原
