【摘要】 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％。更多还原

【Abstract】 The incidence of upper urinary tract stone in flying personnel has been conspicuously higher than that in comparable ground personnel in the same airports. Higher contents of calcium and uric acid in urine resulted from improper diet might be responsible for this phenomenon. Besides, frequent flying and physical exercise causing profuse sweating and a concentration of urine further enhances the above risk factor.About 50% of the patients denied a history of colicky pain while nearly 90% had had gross or microscopic hematuria. In about 20%, repeated KUB failed to reveal the silhouette of the stone. of the 255 cases, 29.4% were renal stones, 16.9% were multiple or bilateral stones and hydronephrosis has been observed in 40%. Spontaneous passage of stone was noted in 34.9% and surgical treatment was undertaken in 20.8%.更多还原
