Species: Feline | Classification: Diseases
- Signs: urinary frequency/mild incontinence to severe urinary retention.
- Diagnosis: difficult to detect radiographically.
- Treatment: most are not treatable (except distal urethra in male: amputation and urethrostomy).
- Chronic dysuria.
- Occasionally signs of uremia Uremia.
- >8 years old.
- Anesthesia Anesthesia: in renal insufficiency if obstructed due to possible electrolyte imbalances.
- Weeks to months.
- Cystitis/urethritis Cystitis: bacterial.
- Mild incontinence.
- Urinary frequency to severe retention.
- Distended bladder if obstructed.
- May be pain on abdominal palpation.
- Positive contrast urethrogram if catheterization possible.
- Positive contrast vaginogram or excretory radiography may allow urethral visualization if catheterization not possible.
- Abdominal radiography Radiography: abdomen may show anterior abdominal mass or enlarged sublumbar lymph nodes .
- Thoracic radiography Radiography: thorax for pulmonary metastases.
- Presence of neoplastic cells in urine sediment Urinalysis: centrifuged sediment - may be present in free catch sample Urine collection: freeflow but not cystocentesis Cystocentesis sample due to location of tumor.
- Surgical or catheter biopsy.
- Transitional cell carcinoma.
- Squamous cell carcinoma Squamous cell carcinoma.
- Granulomatous urethritis.
Initial Symptomatic Treatment
- Little information on treatment in cats.
- Preliminary studies suggest a partial response may be seen with piroxicam Piroxicam.
- Palliative antibiotics and anti-inflammatory drugs.
- Poor for most tumors in female.
- Reasonable for distal urethral tumors in male following surgery.
