(166 cards)
1
Q
What is gross/macroscopic haematuria?
A
Gross/macroscopic haematuria is where there is sufficient enough blood in the urine that it can be seen macroscopically. The urine will typically appear red to brownish
2
Q
What is occlut/microscopic haematuria?
A
Occult/microscopic haematuia is where there are erythrocytes in the urine but they cannot be visualised macroscopically
3
Q
What is pseudohaematuria?
A
Pseudohaematuria is where the urine appears red to brownish but there are no erythrocytes present in the urine
4
Q
What can cause pseudohaematuria?
A
Haemaglobinuria
Myoglobinuria
5
Q
How can you differentiate between true haematuria and pseudohaematuria?
A
Urine sediment examination - erythrocytes will be visible if there is true haematuria but they will not be visible if it is pseudohaematuria
Centrifuge the urine - the erythrocytes will seperate from the urine if it is true haematuria but they will not if it is pseudohaematuria
6
Q
What are the generalised causes of haematuria?
A
Systemic disease
Urogenital disease
7
Q
Which history questions can be useful to determine if haematuria is systemic or urogenital?
A
Has there been bleeding at other sites?
Has there been any recent trauma?
Has there been any exposure to anticoagulant rodenticides?
When does the bleeding start during urination?
Describe the appearance of the urine?
8
Q

Palpate the muscles (may be myoglobinuria due to a myopathy)
9
Q

10
Q

12
Q
Why can there be concurrent haemaglobinuria with haematuria due to renal/ureteral disease?

146
How do you treat bacterial prostatitis?
It is important to check for bacterial prostatitis in entire male dogs presenting with bacteruria or bacterial cystitis as the treatment for bacterial prostatitis is quite different due to the blood prostate barrier - because of this you have to choose very specific antibiotics and adminsiter them for a longer duration
147
