Antispasmodic medication non sedating

These cats should be managed as such (see: Feline Idiopathic Cystitis), but where there are urethral plugs, diets to minimise crystals in the urine may also be helpful (see: FLUTD - treatment).

These procedures have to be done very carefully to avoid damaging the delicate lining of the urethra.

If the obstruction is caused by spasm of the urethral muscle, simply sedating or anaesthetising the cat may be sufficient to allow easy passage of a catheter into the bladder.

However, if there has been a severe blockage, your vet may want to leave a catheter in for a few days (usually no more than 2-3 days) to ensure urine can be produced while treatment is commenced for the underlying disease and inflammation.

Further treatment depends on the underlying cause of the obstruction, the severity of the obstruction, and what (if any) complications have arisen.

Urethral blockage is not a common condition, but when it occurs it is painful, the cat will be unable to urinate despite repeated efforts, and it is a life-threatening emergency as it can cause acute kidney failure and death within 2-3 days if not managed appropriately.

A cat with urethral obstruction will usually show: Depending on the underlying cause, you may also have noticed some other changes in your cat's urinating behaviour over the preceding few days such as increased frequency of urination, straining, discomfort or even some blood in the urine.

Generally under heavy sedation or anaesthesia the urethra passing through the pelvis and penis of the cat will be carefully palpated (felt) to try to locate the region of the obstruction.

Careful massage in some cases is sufficient to relieve the obstruction, but often a catheter needs to be passed into the urethra (via the penis) so that fluids can be infused to help flush out the obstruction (or sometimes to push it back into the bladder).

Once the obstruction has been relieved, your vet will want to infuse a sterile saline solution into the bladder via the catheter so that all the blood and debris (that will inevitably be present in the bladder) can be washed out.

This is usually repeated several times to remove as much debris as possible to reduce the chance of re-obstruction.

To relieve the obstruction, your vet will usually need to sedate or anaesthetise your cat.
