Surgical management of UI is chosen for dogs intolerant of medical treatment or, most often, with progressive and refractory incontinence. In dogs with a caudally positioned bladder (pelvic bladder), the pressure increases that occur with movement, barking, and coughing transmit to the bladder, not the urethra, thus creating a pressure gradient from the bladder to the urethra and resulting in leakage. Behavioral changes are important factors as well. HHS Vulnerability Disclosure, Help Estrogen also appears to have a trophic effect on the periurethral tissues and vasculature and thus may reduce incontinence through improved urethral support. As a result, neutered male dogs are also more likely than unneutered dogs to experience urinary incontinence. These include:, Certain Breeds. This condition is referred to as weak bladder sphincter incontinence. Middle-aged to older spayed female dogs are prone to what is referred to as spay incontinence. This is a form of incontinence commonly caused by lower estrogen levels, which can lead to a loss of muscle tone in the urethra.

The results reported in this case series suggest that testosterone cypionate might be an effective and safe treatment option for male dogs with USMI. In addition, if left untreated, dog incontinence usually worsens over time. However, congenital diseases can become clinical later in life. Although many materials have been investigated, the theory behind all injectable bulking agents is to increase the stretch in the sphincter muscle fibers, leading to increased resting closure pressure in the urethra.

In some cases, urodynamic evaluation can be performed at specialized centers to rule out overactive bladder and confirm the diagnosis of USMI. It enhances glandular function, impacts collagen strength, and increases the number and sensitivity of -receptors in the smooth muscle of the urethra. The need for monitoring for signs of bone marrow suppression with a complete blood count is controversial, and agreed-upon standard of care recommendations cannot be given. For patients with UI that fail medical therapy, or for which medical therapy is not an option, several interventional and surgical options exist.

Here's the information you need on what causes dog incontinence and what you can do about it. Injectable urethral bulking agents, particularly bovine crosslinked collagen, have been used to increase resting urethral pressure in dogs with UI. Your vet may call it Urethral Sphincter Mechanism Incompetence (USMI).

Some surgical and cystoscopic interventions may improve outcome in these patients when medical therapy fails. Among the most commonly affected breeds are the Old English sheepdog, Doberman pinscher, boxer, German shepherd, and Weimeraner.3 Results from a recent study indicate that earlier neutering may increase the risk of USMI development in dogs with a projected adult body weight greater than 15 kg.1, Although many risk factors for the development of UI in dogs have been identified, the mechanism of development remains unclear. Androgens have a variety of uses such as treating hormone-responsive urinary incontinence in male dogs, suppression of heat cycles and alleviation of false pregnancies in female dogs, and as part of the therapy for some types of immune-mediated .

Dogs deposit the urine in the bladder, where this will be held until the bladder is full and the dog will release it through the urethra. Again, context is everything. In addition, treatment frequency can be adjusted (eg, every 5 days rather than every 7) to accommodate the declining response to treatment in some patients without having to increase the capsule size or medicate multiple times a day. Residual urine volume should be measured after voiding in dogs that have a narrow urine stream, exhibit stranguria, or only drip urine. Training for anxiety-inducing behaviors is another way you can help alleviate the condition. Byron JK, Taylor KH, Phillips GS, Stahl MD. . Urethral bulking agent.

The diagnosis is made by assessing urine stream and residual urine volume. The median duration of continence without additional medical therapy ranged from 8 months to 2 years.11, Other surgical therapies for UI focus on increasing the transmission of intra-abdominal pressure to the proximal urethra and improving stability and pressure within the urethra. Congenital causes can be ectopic ureters, congenital urethral sphincter mechanism incompetence, persistent urachus, bladder diverticula, hypoplasia of the bladder, prostate, or urethra, and hypospadia.
