Understanding incontinence requires some primary information about how the conventional urination course of truly works. Your veterinarian makes use of this data to attempt to decide what kind of incontinence is going on.

Urination is a really complicated coordination between muscle mass and nerves. The bladder and the urethra should work collectively to correctly retailer urine and launch it on the acceptable time. There are two phases to this course of: storage and voiding.

Throughout storage, the bladder is relaxed, permitting it to increase and fill with urine. Muscle tissues within the neck of the bladder and the early urethra stay tightened to maintain urine from leaking out. As urine fills the bladder, strain will increase till your cat feels a nerve sign that claims it’s time to urinate.

When your cat arrives on the litter field, the bladder and urethra should shift gears concurrently. The bladder contracts because the urethra relaxes. This permits urine to go away the physique by way of the urethra. As soon as empty, the bladder relaxes and the urethra tightens again up.

Causes of Urinary Incontinence in Cats

So what occurs when the bladder and urethra don’t work so seamlessly collectively? Urinary incontinence in cats usually falls into two classes: issues with the bladder and issues additional down within the urethra. Every kind can have a number of causes.^[1]

1. Bladder

Urge incontinence: One of these incontinence happens when the detrusor muscle mass within the bladder wall contract uncontrollably and intermittently. The bladder sometimes doesn’t have a possibility to fill. This kind can happen with irritation within the bladder wall or urinary tract and when there’s a space-occupying situation inside the bladder (i.e. bladder stones, a mass, or extreme swelling).

Extra particular causes embody:

• Urinary bladder stones
• Some kinds of urinary tract infections
• Bladder mass or tumor
• Persistent bladder irritation resulting in scar tissue formation (fibrosis)
• Irritation from feline idiopathic cystitis (FIC)
• Bladder surgical procedure the place part of the bladder wall was eliminated (partial cystectomy)

Overflow incontinence: It is a situation the place the bladder is far too full however is unable to empty itself usually because of impaired operate of the detrusor muscle mass within the bladder wall. The strain within the bladder physique finally exceeds the resistance of the bladder neck and urethra—so urine dribbles out.

Causes of this sort are often associated to nerves that hook up with the bladder. Spinal wire harm or illness is often accountable.

2. Urethra

Urethral sphincter incompetence: This pertains to the muscle tone within the urethra that’s supposed to stay tight throughout urine storage after which loosen up throughout urination. The “incompetence” refers to when the muscle lacks tone or is “weak” permitting leakage of urine throughout the storage section. Listed here are some causes:

• Weakening over time (particularly in older pets)
• Low ranges of hormones like estrogen and testosterone
• Trauma that impacts the nerves connecting to the muscle
• Different spinal wire illness (irritation, an infection, immune illness, most cancers)

Paradoxical incontinence: One of these incontinence outcomes from a blockage within the urethra. That is usually a urinary stone or mucus plug however will also be from a practical or congenital (beginning defect) drawback with the urethra.^[2] When strain above the obstruction will increase sufficient, urine will leak across the obstruction. The paradox is that there’s truly a blockage current. Almost 70% of cats with non-neurologic incontinence exhibit this sort.^[3]

Causes embody:

• A urinary bladder stone that lodges within the urethra
• A mucus plug that lodges within the urethra (irritation contributes to mucus accumulation and mixes with mineral sediment or grit to type a plug)
• Extreme urethral irritation
• Urethral stricture
• A situation inflicting a malfunction of the urethral muscle (corresponding to reflex dyssynergia) that forestalls urine move.

Signs of Urinary Incontinence in Cats

There could be some overlap between indicators of urinary incontinence and different causes of inappropriate urination. That is what we see mostly:

• Urine leaks out whereas a cat is resting or sleeping
• A cat’s hindquarters is consistently moist or soaked with urine
• Urine dribbles out consistently, even whereas a cat is awake and engaged in regular exercise

Some cats will present different indicators of inappropriate urination as effectively, corresponding to:

• • Straining to urinate
  • Urgency to urinate
  • Extreme licking or grooming of the hindquarters
  • Frequent journeys to the litter field
  • Prolonged intervals within the litter field with little or no urine produced

These different indicators could be seen particularly in circumstances of urge incontinence in addition to paradoxical incontinence.

  • That is the popular imaging methodology for spinal wire illness.
• CT (cat) Scan
  • This take a look at could also be used to search for structural abnormalities or trauma
• Distinction urethrocystogram (or cystourethrogram)
  • It is a particular x-ray take a look at that makes use of a distinction materials to focus on the urinary tract. It may be used to focus on obstructions within the urinary tract or abnormalities in urine move.

Therapies for Urinary Incontinence in Cats

The medicine used to deal with incontinence in cats depends upon the kind of incontinence they’re experiencing.

Urge incontinence could also be handled on the supply of what’s inflicting bladder irritation (cystitis). This will embody a urinary tract an infection, bladder stones, stress cystitis, or a bladder mass. Bladder stones and bladder lots often require surgical procedure.

Feline idiopathic cystitis (FIC) is a urinary illness that vets battle to deal with successfully. Researchers lately completed a examine involving low-dose radiation remedy to see its advantages for power recurrent bladder irritation.^[4]

Dr. Michael Nolan, a professor of radiation oncology and lead researcher, stated, “You possibly can truly deal with arthritis and different inflammatory situations with low-dose radiotherapy and it really works rather well…” He and Dr. Allison Kendall enrolled 15 client-owned cats with FIC of their trial to important success.

Each cat within the examine confirmed some enchancment, with many not having repeat cystitis episodes, and Dr. Kendall sees lots of promise on this remedy. “I really feel assured sufficient within the examine to begin recommending it.”

Overflow incontinence brought on by a nerve harm or illness could also be tough to deal with. Some spinal wire problems could also be addressed with surgical procedure, however many cats should retain a point of incontinence.

If the urinary bladder is stubbornly full and may’t empty, therapy with a mix of bethanechol and phenoxybenzamine could also be tried. Bethanechol will increase the contraction of the bladder detrusor muscle mass, whereas phenoxybenzamine helps the urethral sphincter muscle to loosen up and permit for urination.

Urethral sphincter incompetence could be handled medically. There are not any merchandise permitted to be used in cats. However one product, phenylpropanolamine (PPA), could also be used off-label. PPA works by rising muscle tone of the urinary sphincter muscle, holding the urethra squeezed shut and stopping urine leakage. The principle aspect impact of PPA is that it will probably enhance blood strain. Blood strain is often monitored in pets on this medicine.^[5]

Hormone remedy is usually used to deal with urethral sphincter incompetence in pets. Drugs embody estriol and diethylstilbestrol (DES), that are each similar to estrogen. However estrogens aren’t suggested for cats as a result of they will trigger bone marrow suppression and blood problems. DES has fallen out of favor as a therapy possibility because of a excessive danger of adversarial results.

Paradoxical incontinence, the place some form of obstruction is current, could also be addressed surgically. In a case the place a bodily obstruction, like a urinary stone lodged within the urethra, can’t be relieved, a surgical procedure known as a perineal urethrostomy could also be carried out. This surgical procedure creates a brand new opening earlier on within the urethra the place it’s wider. This creates a brand new exit for urine, leaving the obstruction behind.

Different interventional procedures have been used, together with the placement of a synthetic sphincter known as an occluder to assist maintain the urethra closed to forestall leaking.^[6]
