飞行人员上尿路结石的患病率明显高于同机场的可比性地面人员,不恰当的膳食组成,导致尿中钙和尿酸含量的增高,乃是高发肾、输尿管结石的主要原因。频繁飞行和体育锻炼,出汗多,尿液浓缩,更增强了上述危险因素的作用。临床上,约半数病人无绞痛史,而90％均有肉眼或镜下血尿。近20;了的病例,反复腹部平片未能显示结石阴影,其中约1/4经逆行空气造影,结石阴影得以显示。255例中,肾结石占29.4％,多发或双测结石占16.9％,40％的病例并不同程度的肾积水,自行排石率为34.9％,手术率为20.8％。
The prevalence of upper urinary tract calculi in pilots was significantly higher than that of comparable ground staff at the same airport. Improper diet composition led to an increase in urinary calcium and uric acid levels, which was the main cause of high incidence of kidney and ureteral calculi. Frequent flight and physical activity, sweating, urine concentration, but also enhance the role of the risk factors. Clinically, about half of the patients had no history of colic, while 90% had gross or microscopic hematuria. Nearly 20% of the cases, repeated abdominal plain film failed to show the shadow of stones, of which about 1/4 by retrograde air imaging, stone shadow to be displayed. Of the 255 cases, 29.4% were kidney stones, 16.9% were multiple or double stones, and 40% had hydronephrosis with a degree of 34.9%. The operative rate was 20.8%.
