目的:观察仪仗兵训练性“血尿”的流行病学特征、影响因素及对肾功能的影响。方法:分老兵、新兵组。问卷调查两组在新兵训练期间肉眼“血尿”发生情况,观察其日常正步训练前后尿液及肾功变化。结果:两组总的肉眼“血尿”累计发生率为30.9%,老兵组晨尿渗透压为850.5±248.9 mOsm·kg~(-1)·H_2O~(-1),训练前后尿检结果明显异常者分别为5.9%和34.5%(P<0.01);新兵组晨尿渗透压为920.9±742.4 mOsm·kg~(-1)·H_2O~(-1),训练前后尿检结果明显异常者分别为5.2%和49.5%(P<0.01)。尿液检测证实为血红蛋白尿;训练负荷增大,血尿的发生率增加;两组肾功检查均正常。结论:仪仗兵的训练性血红蛋白尿与穿着硬底训练靴有关,饮水不足,训练负荷过大可能加重尿检异常,尿检异常是一过性的,可自行恢复,未发现对肾脏有器质性影响。
OBJECTIVE: To observe the epidemiological characteristics, influencing factors and renal function of guerrillas trained “hematuria”. Methods: sub-veterans, recruits group. Questionnaire survey during the recruits training two groups of “hematuria,” the incidence of observation before and after daily routine training urine and renal function changes. Results: The cumulative incidence of gross hematuria in the two groups was 30.9%. The morning urine osmolality of veterans was 850.5 ± 248.9 mOsm · kg -1 · H 2 O -1, and the urine test results were obviously abnormal before and after training (P <0.01). The morning urine osmotic pressure of recruits was 920.9 ± 742.4 mOsm · kg -1 · H 2 O -1, and the abnormal urine tests before and after training were significantly different (5.2% And 49.5% (P <0.01). Urine test confirmed hemoglobinuria; training load increased, the incidence of hematuria increased; renal function tests were normal in both groups. CONCLUSIONS: Guerrillas’ training hemoglobinuria is related to wearing hard-bottom training shoes, lack of drinking water and excessive training load may aggravate urinalysis abnormalities. Urinalysis abnormalities are transient and self-recovering without any organic effect on the kidneys .
