Treatment

The obstruction must be relieved as soon as possible. Sedation is often necessary. Depending on the severity of the obstruction, several methods may be used by the veterinarian to remove the obstruction -- urethral massage and using fluid to push the obstruction out of the urethra and into the bladder are two examples.

Once the obstruction is removed or pushed back into the bladder, a urinary catheter is sometimes left in place and is maintained for at least 24 hours, depending on the cause of the obstruction.

Intravenous (IV) fluids are usually administered to rehydrate the cat and normalize its electrolyte levels. Because of the pressure buildup and the inability to eliminate urine and its components, the entire renal system is affected and kidney damage can occur. In most cases, this damage is repaired with adequate fluid and electrolyte administration. Medications to treat the pain may also be necessary.

Living and Management

It is important to monitor the flow of urine to ensure that there are no visible signs of complication. Cats are especially prone to repeat obstructions due to their tendency for uncontrolled urethra spasms. Some causes of urethral obstruction can be treated and eliminated, others cannot. Therefore, carefully monitoring the pet is very important.

Dietary changes may be necessary to prevent crystals, stones or other potential causes of the obstruction. Ensuring a cat has a clean and safe litter pan can also help.
