Feline Lower Urinary Tract Disease Flashcards
Define feline lower urinary tract disease/feline urological syndrome
Collective terms for signs of lower urinary tract disease and abnormal voiding behaviour
FLUTD is a collective term for a variety of conditions affecting the bladder and/or urethra of cats that result in similar clinical signs
Name some non-obstructive feline lower urinary tract diseases
- Idiopathic cystitis
- Uroliths
- Anatomical defects, cancer, etc
- Behavioural problems
- Bacterial infection
Name some obstructive feline lower urinary tract diseases
Idiopathic cystitis
Uroliths
Urethral plug
Bacterial infection
What is feline idiopathic cystitis?
- Abnormal voiding behaviour after exclusion of other disorders
- No obvious cause
- Chronic, persistent or recurrent
Which animals are predisposed to lower urinary tract infections?
Any age or sex - young to middle-aged neutered cats, 2-6 years old
Males more prone to obstruction
Persians appear predisposed
List the 4 predisposing factors for lower urinary tract disease in cats
Obesity
Indoor / sedentary cats
Dry diet
Multi-cat household
How will a cat with lower urinary tract disease present?
Dysuria (difficulty urinating)
Pollakiuria (increased frequency)
Haematuria
Inability to urinate (urethral obstruction)
Behavioural changes
Appear to lose litterbox training
What is the term used to describe urinating in inappropriate places?
Periuria
How do cats with non-obstructed lower urinary tract disease most commonly present?
- Generally well
- Usually self limiting and resolves in 5-10 days
- Bladder small, firm and may be painful
How do cats with obstructed lower urinary tract disease most commonly present?
Emergency situation!
Large, painful bladder
Check penis for signs of trauma/crystals
Dehydration, uraemic breath, bradycardia
Bladder may rupture = non-palpable, abdominal pain
Describe the pathophysiology of feline idiopathic cystitis
- Alterations in neurotransmission to and from the bladder lead to inflammation
- Reduced glycosaminoglycan layer, which protects the bladder lining
- Get petechial haemorrhages on the bladder wall
How is ‘pandoras syndrome’ linked to FIC?
Cats with chronic LUT signs in the presence of comorbid disorders (e.g. behavioural, cardiovascular, dermatological, GI problems)
Describe the main features of urethral plugs
- More common in males (longer, narrower urethra)
- Most common cause of obstruction
- Plug consists of mucus / glycoprotein matrix, often with other substances trapped in the matrix
Name the 3 urolith types seen in cats
Struvite
Calcium oxalate
Urates
How are struvite uroliths different in dogs and cats?
Struvite uroliths in cats are most commonly sterile (different to dogs where they are usually associated with UTIs)
Describe UTIs in cats
Rare!
