Feline Lower Urinary Tract Disease (FLUTD): Causes, Symptoms, and Treatment
Feline Lower Urinary Tract Disease (FLUTD) is a common and potentially dangerous condition affecting a cat's lower urinary system. Symptoms include difficult urination, bloody urine, and frequent urination. In severe cases, it can lead to a urinary blockage, especially in male cats. Early diagnosis and proper management are crucial for a good prognosis.
What is FLUTD?
FLUTD (Feline Lower Urinary Tract Disease) describes a group of pathological conditions affecting a cat's bladder and urethra. It is not a specific disease but a syndrome with multiple potential causes.
Causes
The most common causes include:
Feline Idiopathic Cystitis (FIC), which is the most common cause. Uroliths (struvite, calcium oxalate). Urethral plugs (plug formation). Bacterial infections (less common in young cats). Urinary tract neoplasms. Anatomical abnormalities or trauma.
Symptoms
Clinical signs may include:
Dysuria (painful urination). Polyuria and frequent attempts to urinate. Hematuria. Urination outside the litter box. Excessive licking of the genitals. Complete urethral obstruction (an emergency), with absence of urination, lethargy, and possible vomiting.
Diagnosis
The diagnostic approach includes:
Clinical examination. Urinalysis. Radiography or ultrasound. Urine culture (where indicated). Hematological and biochemical tests in severe cases.
Treatment
Treatment depends on the underlying cause:
Dietary management (special urinary diets). Increased water intake. Analgesics and anti-inflammatory drugs. Antispasmodics or anxiolytics for FIC. Antibiotics (only for confirmed infection). Catheterization in case of urethral obstruction (emergency intervention).
Prevention
Prevention is mainly based on:
Adequate hydration (e.g., wet food, multiple water sources). Reducing stress in the cat's environment. Clean and adequate litter boxes. Appropriate diet. Maintaining a healthy body weight.
Prognosis
The prognosis is generally good but depends on the cause and timely treatment. Recurrences are common, especially in cases of idiopathic cystitis.
