In a review of 27 cases treated with an artificial urethral sphincter, all had significantly improved continence, with only 2 dogs having complications involving partial urethral obstruction.9, Injectable urethral bulking agents have been used, particularly bovine cross-linked collagen, to increase resting urethral pressure in dogs with UI. .

Some studies findings have implicated a rise in luteinizing hormone and gonadotropin-releasing hormone (GnRH) levels as well as increases in their receptors in female animals secondary to the decline in estrogen levels after neutering.4,5 These changes may affect smooth muscle contractility in the lower urinary tract.

Sometimes we can use testosterone in males. 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.

Urethropexy may have an increased complication rate (21%) compared with colposuspension, with surgical revision being required in animals with urethral obstruction.21, A recent report of a combined technique of urethropexy and colposuspension revealed an improved success rate (70%) and durability compared with either procedure alone, as well as fewer complications (10%).22. The pet can urinate normally, but they leak urine while resting. "At the time of the inquiry, the average age of the bitches was 6.5 years and the average age at the time of surgery was 7.1 months," the study sates. For at least three years they were questioned about the occurrence of urinary incontinence. This is possibly caused by misdiagnosis of dogs with functional urethral obstruction and overflow incontinence. Vulvovaginal stenosis, a condition in which the vagina at the level where the urethra ends is narrowed, is a less common cause of incontinence in female dogs. The mechanisms behind this familiar condition are multilayered and poorly understood, and treatment must be individualized based on the cause of the problem.

Acquired causes can be hyperreflexia of the detrusor muscle, acquired urethral sphincter mechanism incompetence, detrusor atony because of bladder over distention, prostatic disease, neoplastic disease of the bladder, prostate or urethra, or neurologic disease (lower motor neuron disease). Residual urine volume should be measured after voiding in dogs that have a narrow urine stream, exhibit stranguria, or only drip urine. For example, your vet can prescribe drugs to strengthen the bladder muscles if no specific cause for incontinence can be found. Illustration by Diogo Guerra, medical illustrator.

With diseases like ectopic ureters or urethral sphincter mechanism incompetence the dogs urinate normally, while with diseases like urinary tract infection or neoplasia pollakiuria or stranguria can be seen. Colposuspension, which attaches the uterine remnant to the pelvic ligament and thus draws the bladder neck and proximal urethra farther into the abdomen, has been found to have variable success and a high failure rate due to breakdown of the attachment to the pelvic ligament.12.

The dog should also have its blood pressure monitored after 2 to 4 weeks on the medication. Danazol, mibolerone, and testosterone are all examples of androgens, a class of steroid hormones. When a female dog is spayed, both her uterus and ovaries are removed. The larger the dog, the more pronounced this alteration in risk becomes. The decision of when to spay a dog can be challenging. Dogs that do not respond to appropriate medical therapy should be evaluated for other lower urinary tract disease via imaging, including abdominal ultrasound and/or contrast radiography.

MeSH This might be the case in urethral sphincter mechanism incompetence. In addition, purebred dogs are more likely to suffer from involuntary leaks than their crossbred counterparts, as line breeding can cause more genetic problems. 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. The etiology of functional obstruction or DUD is elusive and may involve the reticulospinal tract. Surgical therapy of urinary incontinence has traditionally focused on increasing the transmission of intra-abdominal pressure to the proximal urethra or improving the stability and pressure within the urethra. The hormones (testosterone in males and estrogen in females) impact a dog's ability to control the urethral sphincter, a band of muscular tissues near the base of the bladder. Epub 2021 Jan 14.

Training for anxiety-inducing behaviors is another way you can help alleviate the condition. The material is injected submucosally into the proximal urethra via cystoscopy (Figure). Some practitioners avoid the use of estrogen compounds because of the potential for irreversible myelosuppression seen in dogs treated with estrogen compounds for mismating or to induce estrus.8,9 While this is a potential toxicosis, the doses associated with bone marrow suppression are generally at least 10 times higher than those recommended for management of UI. Typically, dogs respond well to medication; however, if your pet's incontinence persists, you may opt for diapers which can be purchased in pet stores.

Hypertension, or a predisposition to hypertension caused by concurrent disease, is a major contraindication to using PPA. Young dogs that have never been continent or have been difficult to housetrain should be evaluated for congenital abnormalities, such as ectopic ureter(s).

Dribbling pee can occur due to a urinary tract infection (UTI). As with estriol, these are usually dose-related and subside with dose reduction. Medical therapy of urinary incontinence in ovariectomised bitches: a comparison of the effectiveness of diethylstilboestrol and pseudoephedrine. In spayed female dogs, this is acceptable; however, in intact females and in males, further evaluation for other urinary tract disorders, particularly urethral functional obstruction and overflow incontinence, is warranted.
