Definitions:
Normally the number of RBCs in urine should not be more than 5 RBCs/ high power field on microscopic examination of fresh centrifuged urine sample.
Haematuria
So, haematuria is defined as a secretion of more than 5 RBCs/ HPF in urine.

Haematuria may be the only symptom or may be associated with other manifestations, according to the cause e.g. loin pain and fever with infection and renal colic with renal stones.
Haematuria could be gross (causing red-coloured urine) or microscopic (urine appears normal but RBCs are seen on microscopic examination). In gross hematuria, urine looks red if alkaline, but brown or coca-cola like if urine is acidic due to denaturation of the hemoglobin.

Transient microscopic haematuria is relatively common. Up to 39% of adults between ages of 18 and 33 may have microscopic haematuria at least once, and up to 16% may have it in two or more occasions. Therefore, an extensive workup is not warranted except in high-risk patients, > 50 years of age and those patients with other clinical or urinary abnormalities.

Initial is usually urethral.
Terminal hematuria is usually prostatic or bladder origin.
Total hematuria is either bladder ureteral or renal origin.
Patterns Of Haematuria

Differential Diagnosis of Haematuria:A. First, haematuria should be differentiated
from other causes of red or brownish urine:Dipsticks (Hemastix) will be positive with
haematuria, hemoglobinuria (hemolysis) and with myoglobinuria (muscle damage) but negative with other causes e.g. prophyrins (in porphyria), bile (in jaundice), melanin (in melanoma), alkaptonuria, food dyes and drugs as PAS or phenylphthalein.
Microscopy will show RBC’s only with haematuria.
Urology & Nephrology Center, Mansoura University, Egypt
False positive test for haematuria:
Haemoglobinuria.
Myoglobinuria.
Ascorbic acid.
False negative test for hematuria:
Highly diluted urine.

Haematuria could be glomerular (because of glomerular disease, sometimes called medical); or non glomerular (sometimes called surgical).
1. The shape of RBCs in urine are small and dysmorphic in cases with glomerular haematuria while it will be normal in case of non glomerular haematuria.
Glomerular haematuria could be differentiated from non glomerular haematuria by:
Urology & Nephrology Center, Mansoura University, Egypt
2. Means corpuscular volume of RBCs in urine of patient with glomerular haematuria is smaller (< 72 FL) than that in peripheral blood, but in non glomerular cases is equal.
3. Proteinuria is present in most cases of glomerular hematuria but not in cases of non glomerular hematuria.
4. Casts, especially red cell casts are seen in glomerular haematuria.
5. Blood clots indicate non-glomerular bleeding and can be associated with pain & colic.
6. Three-glass test.

First exclude haemoglobinuria and myoglobinuria since both of them can also cause positive dipstick test for haematuria. This is done by microscopic examination of fresh urine sample. In case of haematuria, RBCs could be seen while in the other two conditions no RBC’s could be seen.
Approach to a case of haematuria
Urology & Nephrology Center, Mansoura University, Egypt
In case of myoglobinuria, clinical examination may show manifestations of muscle disease and the examination of urine by immunoelectrophoresis may show myoglobin.
In case of haemoglobinuria, manifestations of haemolysis may be evident

RBCs in urine could be examined for its shape to differentiate glomerular (small, distorted) from non glomerular causes (by phase contrast microscopy).
Kidney function tests.
Specific investigations for diagnosis of systemic disease causing haematuria e.g. SLE.
Endoscopic study: to diagnose neoplastic disease , UB ulcers
Kidney biopsy: for glomerular haematuria.
