问题 单项选择题

病理改变在肾、临床表现在膀胱,最常见于泌尿系统什么病

A.肾癌
B.肾结石
C.肾结核
D.肾炎

答案

参考答案:C

解析:[考点] 肾结核
[分析] 肾结核是继发性结核,绝大多数起源于肺结核,结核菌经血行进入肾,主要在肾小球周围毛细血管丛内,形成微小结核病灶,如病人免疫状况很好,这种微小结核病灶可自行愈合,不出现临床症状和影像学改变,称为病理性肾结核;如病人免疫力低下,这种微小结核灶逐渐扩大,病变累及集合系统后,含有结菌的脓尿经肾盂、输尿管排入膀胱,刺激膀胱黏膜,遂出现尿频、尿急、尿痛等临床症状,称临床肾结核;随后输尿管、膀胱受感染出现结核病灶,症状加剧,晚期膀胱产生挛缩,容量显著减小,尿频更加严重,甚至尿失禁,因此正确答案是C。

Death Valley is one of the most famous deserts in the United States, covering a wide area with its alkali sand Almost 20 percent of this area is well below sea level, and Badwater, a salt water pool, is about 280 feet below sea level and the lowest point in the United States.

Long ago the Panamint Indians called this place “Tomesha”— the land of fire. Death Valley’s present name dates back to 1849, when a group of miners coming across from Nevada became lost in its unpleasantness and hugeness and their adventure turned out to be a sad story. Today Death Valley has been declared(宣告)a National Monument(纪念碑)and is crossed by several well-marked roads where good services can be found easily. Luckily the change created by human settlement has hardly ruined the special beauty of this place.

Here nature created a lot of surprise, almost like the sights on the moon, ever-changing as the frequent(频繁的)wind moves the sand about, showing the most unusual colors. One of the most surprising and variable(多变的)parts of Death Valley is the Devil’ s Golf Course, where it seems hard for one to tell reality from terrible dreams. Sand sculptures(沙雕)stand on a frightening ground, as evening shadows move and lengthen.
