Even having red blood cells that you can't see called microscopic hematuria.

即使有你看不见的红细胞也叫微观尿。

Urinalysis and its sediment may reveal hematuria, pyuria, proteinuria, and cellular casts.

尿液分析及其沉淀物能显示尿、脓尿、蛋白尿和细胞管型。

This can again cause hematuria, blood in the urine, as well as flank pain.

这会再次尿，即尿中有，以及侧腹。

In addition, clogging in the renal papillae can cause necrosis, which can manifest as hematuria and proteinuria - blood and protein spilling out into the urine.

So when there is glomerular injury, red blood cells sneak into the urine —causing hematuria, which contributes to this being a type of nephritic syndrome.

因此当肾小球损伤时，红细胞溜进尿液，尿，也是肾炎综合征的一个症状。

When damaged, therefore, membrane permeability increases and large molecules are allowed to be filtered into the urine like proteins, called proteinuria, and even red blood cells, called hematuria.

当足突细胞受损时，膜通透性增加，大分子被允许过滤到尿液中：像是蛋白质，造成蛋白尿；甚至是红细胞，造成尿。

Diagnosis involves a history and physical exam, as well as imaging studies like X-rays, CT scans or ultrasound, and finally urinalysis because it might show microscopic or gross hematuria or blood in the urine.

诊断基于病史、体格检查，X光、CT平扫、超声等影像学检查，最后还有尿常规，因为它以显示镜下尿或者肉眼尿，即尿液中有。
