Specific treatment of an underlying disease or condition with surgery or medications may resolve incontinence. Byron JK, Chew DJ, McLoughlin ML. Similar to colposuspension, this increases transmission of intra-abdominal pressure increases to the urethra as well as the bladder and bladder neck, preventing a negative pressure gradient into the outflow tract. Blood tests can detect evidence of kidney damage from infection or for the presence of diseases that might lead to increased urine production. Overexertion or stress can cause incontinence in dogs, and it can disappear as quickly as it appears. It appears that the obstruction can involve either the smooth or skeletal muscle of the urethra or a combination. Problems like a UTI or kidney issues usually benefit from more moisture with their food. A dog that is dripping urine is not only an issue of smell and hygiene but often a symptom of underlying health issues. Testosterone will cause the urinary sphincter to tighten and regain control again. Testosterone may help to increase urethral smooth muscle tone and prostatic urethral resistance. 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. Dr. Byron is a clinical professor in the Department of Veterinary Clinical Sciences at The Ohio State University.

Based on owners' assessments, a good to excellent response was reported in three of eight dogs (38%), a slight response was reported in one of eight dogs (12%), and a poor response was reported in four of eight dogs (50%).

Cystoscopy is routinely performed in patients with urinary incontinence to rule out anatomic abnormalities that may be contributing to clinical signs. In humans, this is often managed with procedures that stabilize the mid-urethra during increases in abdominal pressure, using a surgically placed tape to pull the vagina and urethra against the pubis. 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. Stimulation of 1A receptors in the smooth muscle of the urethra and bladder neck leads to increased urethral closure pressures and is an important part of resting urethral tone. Danazol, mibolerone, and testosterone are all examples of androgens, a class of steroid hormones. Clinic for Small Animal Internal MedicineVetsuisse FacultyUniversity of ZrichZrich, Switzerland.

Urinary incontinence is a problem that affects some dog breeds more than others. Oftentimes the dogs only lose urine while sleeping. This equalizes the pressure between the bladder and its outflow tract, preventing leakage. PPA has also been used safely in cats with UI, although there are little data available regarding its efficacy. 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. Medical therapy is directed at the smooth, and sometimes skeletal, muscle of the urethra to either improve contraction or enhance relaxation. In the spayed female dog, the removal of the negative feedback effect of estrogen leads to increases in follicle stimulating hormone (FSH) and luteinizing hormone (LH). The diagnosis is made by assessing urine stream and residual urine volume. Estrogen supplementation is also an available option, where your vet may prescribe estrogen-based medications such as estriol. The low response rate in males might be due to the difficulty in differentiating detrusor weakness from urethral incompetence.

Urinary tract disorders and bladder infections are just a few possible causes. -Antagonists are a mainstay of smooth muscle relaxation, while the addition of low doses of diazepam just before urination can relax the skeletal muscles. This is because the urinary tract tissue's proper functioning depends on adequate estrogen exposure, and a pet's estrogen levels are low after her ovaries have been removed.
