文章导读

很多人对尿隐血病不是很了解,尿隐血病是泌尿科常见的疾病,引起这一现象的最主要的病因有肾脏的疾病,尿路感染的疾病,以及全身性的疾病,因此通过尿常规检查发现尿潜血阳性,就要首先警惕肾脏的疾病,而且尿隐血病还容易和一些症状相混淆,例如尿蛋白,尿糖。

引起尿潜血的原因和多,可有暂时性和持续性之分。如剧烈运动后、精神过度紧张时和脱水后都会出现暂时的尿隐血,这种情况一般经过一两天就会自行消失,并无大碍。但是持续性尿隐血就比较严重了,如上呼吸道感染、发热性疾病、肾炎、肿瘤、结石、结核泌尿系统感染等都会引起尿潜血,这时候我们就应高度重视,要做出进一步的诊断来确定病情,并及时进行诊治。

尿隐血阳性怎么办?

在检查结果出来后,潜血困扰着某些人,除去运动型血尿、药物性血尿等客观因素外,我们还应进行相关的检查以确诊,当排除泌尿系感染、结石、肿瘤等因素外,应考虑肾脏疾病的可能性。此时应尽快到医院就诊,很多尿潜血患者便是在初期忽视治疗从而延误病情。

在肾脏疾病中,如急慢性肾炎、肾盂肾炎等都会出现血尿,当各种病理损伤导致受损肾脏局部微循环障碍而使肾脏组织缺血、缺氧,从而释放炎性介质,启动肾脏纤维化的进程。此时肾小球会发生局部病理改变:系膜细胞增生,系膜基质增多,肾小球基底膜发生改变,导致电荷屏障损伤,肾脏通透性增加,从而会出现尿潜血、蛋白尿。

随着血尿、蛋白尿的漏出,肾脏损伤也进一步加剧,肾小球也逐步进展到纤维化、硬化阶段。临床上应采取系统地针对性的治疗,及时阻断肾脏纤维化的进程,避免因功能肾单位的逐渐减少而导致肾功能衰竭。

目前对待尿潜血,主要有以下方式:

①常规用药,能消炎就消炎,不能的话,优先消除尿蛋白;

②除非出现肉眼血尿,否则不做过于积极的治疗

What do you do with positive urine occult blood?

After the examination results, occult blood puzzles some people, except for the objective factors such as sports hematuria, drug hematuria and other objective factors, we should also carry out the related examination to confirm the diagnosis. When the factors such as urinary infection, stone, tumor and other factors are excluded, the possibility of kidney disease should be considered. At this point, the hospital should be sent to the hospital as soon as possible. Many urine occult blood patients are neglected in the initial stage of treatment so as to delay the disease.

In renal diseases, such as acute and chronic nephritis, pyelonephritis and so on, hematuria will occur. When various pathological injuries cause local microcirculation impairment in damaged kidneys, the renal tissue is ischemic and anoxic, thus releasing inflammatory mediators and starting the process of renal fibrosis. At this time, the glomeruli will have local pathological changes: the proliferation of mesangial cells, the increase of mesangial matrix, the change of the glomerular basement membrane, the damage of the charge barrier, the increase of the permeability of the kidney, and the occurrence of urinary occult blood and proteinuria.

With the leakage of hematuria and proteinuria, kidney injury is further aggravated, and the glomerulus is progressing to fibrosis and hardening stage. In clinical, systematic and targeted treatment should be taken to block the process of renal fibrosis in time and avoid renal failure due to the gradual reduction of functional kidney units.
