Blood and protein in urine
What does blood and protein in urine mean?
If both protein and blood are found in the urine, that means you have problems in your renal glomerulus. The renal glomerular diseases, especially the glomerulonephritis, often lead to blood in urine or red blood cells in urine. In these cases, this bloody urine can be distinguished from that caused by urinary-tract infection, stones, and cancers.
The characteristics of blood urine caused by renal glomerular diseases in most cases:
- Blood in urine no pain;
- Blood in urine during the whole process of urination;
- Accompanied by protein in urine many of the time;
- Blood in urine with relatively large number of proteins in urine indicates glomerular hematuria - blood in urine caused by renal glomerular diseases.
The characteristics of blood in urine caused by kidney stones, kidney infection or kidney cancer in most cases:
- No protein in urine.
- Blood in urine no pain (kidney cancer, renal pelvic tumor);
- Blood in urine with pain (kidney stones and kidney infection; some cases of kidney cancer as well, especially in advanced stage);
- Kidney pain and painful urination;
- Cloudy urine due to kidney infection (precisely, pyelonephritis - the inflammation of the kidney and its pelvis due to bacterial infection), secondary infection due to kidney stones.
What causes blood and protein in urine?
Blood and protein in urine can occur in any age, in children, young people, women, men, also during pregnancy. The main causes are various glomerular diseases of the kidney, such as glomerulonephritis, also usually seen in nephrotic syndrome, IgA nephropathy, diabetic nephropathy accompanied by renal papillary necrosis.
