CASECASE
An otherwise healthy 48-year-old woman is
found to have microscopic hematuria (5 red cells
per high-power field) on a urinalysis performed
by a life insurance company. No other laboratory
abnormalities are identified; the serum creatinine
concentration is 0.8 mg per deciliter (70.7 µmol
per liter). The woman reports no symptoms and
is a nonsmoker. Her blood pressure is 118/74
mm Hg, and the findings on physical
examination are normal. How should she be
evaluated?
DEFINITIONDEFINITION
More than three red blood cells are found in
centrifuged urine per high-power field microscopy
( > 3 RBC/HP).
Normal urine:
no red blood cell or less than three red blood cell
>3RBC/HPF from two of three urinary sediments
without a urinary tract infection, or menstruation on
microscopic evaluation

It is difficult to localize the site of
bleeding by routine examination of the
patient with hematuria.
However, certain findings may be very
helpful depend on size & shape of RBCs.
For example, casts form in the
lumina of renal tubules.
Therefore, the presence of RBCs
casts localizes the site of bleeding
to the renal parenchyma.

Important areas to check on the physical
examination
•Blood Pressure
•Check for edema, especially around the eyes
•Careful inspection of the external genitalia
•Look for any rashes, evidence of trauma and bruising, petechiae
•Exam all joints for signs of arthritis-red, warm, or swollen
•Feel the abdomen carefully for any masses or tenderness. Check for CVA
tenderness. Try to feel for enlarged kidneys.
•Check for evidence of paleness or jaundice
•Accurately measure length and weight and plot on growth chart.

Urine CytologyUrine Cytology
The sensitivity of urine cytology for the diagnosis of
urothelial cell cancer is low, and a negative result does not
exclude patients from further testing.
It has been shown in multiple studies that the addition of
urine cytology in the primary analysis of hematuria does
not contribute to diagnosis which is usually made by
cystoscopy or imaging.
Urine CultureUrine Culture
The addition of cultures of urine may be
indicated if the sediment shows leukocytes.

CystoscopyCystoscopy
The American Urological Association best practice policy
suggests that, in patients at low risk for urothelial cancer,
cystoscopy may be avoided.
Imaging of the bladder should preferably precede
cystoscopy, so it can aid the urologist and improve
diagnostic yield.

Abdominal RadiographsAbdominal Radiographs
Its overall sensitivity for renal and ureteral stones
is only 45–60% in multiple studies
Non-contrast CTNon-contrast CT
It is now the reference standard for stone
detection, and even very-low-dose unenhanced CT
techniques with a radiation dose comparable to
that of abdominal radiographs have shown better
results
ADPKDADPKD
UltrasoundUltrasound
Ultrasound is suitable as first-line diagnostic test
In comparison with excretory urography, ultrasound
showed a higher sensitivity for bladder tumors and equal
(i.e., moderate) sensitivity for upper urinary tract tumors.
Ultrasound alone is not sensitive (19–32%) for stone
detection,
ADPKDADPKD
Excretory UrographyExcretory Urography
For hematuria, multiple studies have now shown
the superiority of CT urography over excretory
urography.
There is also a low sensitivity (< 60%) for renal
tumors smaller than 3 cm for excretory urography

MR Urography (MRU)MR Urography (MRU)
MRU has inherent advantages
in that it does not require
ionizing radiation, has a high
contrast resolution, has good
sensitivity for contrast media,
and has the possibility for
better tissue characterization
than other imaging techniques
do
MR Urography (MRU)MR Urography (MRU)
However, MRU is costly, technically demanding,
and not widely practiced.
Therefore, MRU expertise is available only in
specific dedicated centers.
It is good for pediatric diseases and for the
evaluation of obstructive disease.

Visible haematuria coinciding with intercurrent (usually upper
respiratory tract) infection
Exercise induced hematuriaExercise induced hematuria
•Gross or microscopic hematuria that occurs after strenuous exercise and resolves
with rest
•Direct trauma to the kidneys and/or bladder may be responsible for the hematuria
•Renal ischemia due to shunting of blood to exercising muscles
•Exercise-induced gross hematuria should be differentiated from two other
potential causes of red to brown urine following exercise: myoglobinuria due
to rhabdomyolysis; and march hemoglobinuria
•Evaluation is not warranted in patients under age fifty who are not at increased
risk for bladder or kidney cancer
•Evaluation for other causes of hematuria is warranted if the hematuria persists
well beyond one week
Henoch–Schönlein purpuraHenoch–Schönlein purpura
HSP is a systemic vasculitis (inflammation of blood
vessels) and is characterized by deposition of immune
complexes containing the antibody IgA.
Rash, arthritis, abdominal pain and hematuria
C/P of poststrept GNC/P of poststrept GN
In general, the latent period is 1-2 weeks after a throat
infection and 3-6 weeks after a skin infection.
Dark urine (brown-, tea-, or cola-colored)This is often
the first clinical symptom.
Dark urine is caused by hemolysis of red blood cells
that have penetrated the glomerular basement
membrane and have passed into the tubular system.
C/P of poststrept GNC/P of poststrept GN
The onset of puffiness of the face or eyelids is sudden. It
is usually prominent upon awakening and, if the
patient is active, tends to subside at the end of the day
In some cases, generalized edema and other features of
circulatory congestion, such as dyspnea, may be
present.
Edema is a result of a defect in renal excretion of salt
and water.
Gross hematuriaGross hematuria
Gross hematuria is suspected because of the presence
of red or brown urine.
The color change does not necessarily reflect the
degree of blood loss, since as little as 1 mL of blood per
liter of urine can induce a visible color change.
Gross hematuria with passage of clots almost always
indicates a lower urinary tract source.
The initial step initial step in the evaluation of patients with red
urine is centrifugation of the specimen to see if the red
or brown color is in the urine sediment or the urine
supernatant.
