Answer 10

Excess haemoglobin in the blood

Likely indicative of intravascular haemolysis therefore; anaemia, agglutination, underlying cause

Zinc, onions, cu, 
venal caval syndrome 
DIC 
microangioapthy 
Inherited RBC defect 
Snake enevenomation

Question 13

Haematuria - Very common

Answer 13

Blood in urine
Locate where the blood is coming from
Check the urogenital structure for local bleeding lesions
if none found, and perhaps bleeding is occurring elsewhere, consider a haemostatic disorder as the root of cause
e times of urination

Question 14

what are your DDx for haematuria

Answer 14

Bleeding from genital structure
Bleeding from the urinary tract
Underlying haemostatic disorder

Question 15

Is the bleeding only at the beginning or end of the urine stream ?

Answer 15

indicative that not in the bladder i.e lower down

Urethral lesion

Question 16

Does bleeding from the prepuce or vulva occur at times other than urination

Answer 16

if bleeding occurs at times other than urination it indicates something towards the end of the urinary tract

Question 17

Is bleeding associated with a lot of straining and increased frequency of urination?

Answer 17

Indicative of lower urinary tract issue

Straining anf increased frequency - think lower urinary tract - think bladder and urethra

Question 18

Are RBC cast present in the urine sediment?

Answer 18

Cast of the kidney tubules - blown out by the next urine made by that nephron- if they are present in the urine it indicates an urinary tract issue

Question 19

Is blood found in voided, but not in cystocentesis-derived urine samples?

Answer 19

The lesion could be urethra and beyond - could be genital - lower or further distal than the urinary bladder

if the cystocentesis sample is normal means that there is no lesions in the bladder of the animal

Question 20

Otto occ has blood at the start of his urine stream. From time to time he also drips blood from his prepuce at time other than urination otherwise he is well. Where is the bleeding coming from

Answer 20

Prostate, urethra, VWB, bleeding lower down structure

Answer 21

Kidneys

Question 22

what are the causes of straining

Answer 22

Obstruction and inflammation (more common)

Answer 23

signs: pollakiuria, stranguria, dysuria
- stone lodged in caudal aspect of os penis
- Calculi
Mucous, struvite pulgs
neoplasia
Functional

Question 24

Lower urinary tract inflammation

Answer 24

Cats are much less prone then dogs Bacterial infection F more than M
Sterile idiopathic urethrocystitis
Bladder (or cystic) calculi
Neoplasia

Question 25

what is your approach to a patient with pollakiuria/stranguria/ dysuria

Answer 25

Palpate the bladder and do a rectal exam, ideally before and after the animal is allowed to void urine. Feel for calculi, masses, thickening, bladder enlargement obtain urine by cytocentesis for UA, culture and sensitivity consider imaging studies
