WHAT IS FELINE IDIOPATHIC CYSTITIS (FIC)?

Feline Idiopathic Cystitis (FIC), also known as feline interstitial cystitis is a common condition in cats marked by chronic bladder inflammation without a clear cause. It can be challenging for both cats and their owners, with symptoms including: Straining to urinate (stranguria) Blood in the urine (hematuria) Frequent or urgent attempts to urinate (pollakiuria) Pain or discomfort during urination Urinating outside the litter box In severe cases, complete urinary obstruction FIC is typically a diagnosis by exclusion since very rarely is a bladder biopsy performed. Other possible causes like infections, bladder stones, tumors, etc. are ruled out first.

RADIATION THERAPY: A NEW TREATMENT OPTION

We are excited to offer radiation therapy as a novel treatment option for cats with FIC, inspired by a clinical trial at North Carolina State University (NCSU). Though final results are still pending, early findings are promising:

• 90% resolution of symptoms over one year.

• This is a single-session, low-dose radiation treatment targeting the lower urinary tract (bladder). It involves a CT simulation (a radiation planning CT scan) followed by the treatment itself, both performed under anesthesia or sedation.

• Timeline: The process can be completed in one day (CT scan and radiation together) or split, with the CT scan one day and the radiation treatment the next, depending on scheduling and your cat’s needs.

Unlike radiation therapy treatment for cancer and other diseases, this treatment does not require multiple visits.

IS YOUR CAT ELIGIBLE?

Radiation therapy may benefit cats with FIC who meet these general criteria:

• Persistent urinary issues like straining, bloody urine, or frequent urination

• Cats with or without a history of urethral obstructions

• Male cats may show a stronger response, based on early data

• No underlying causes (e.g., infections, stones, or tumors) identified
