Ectopic Ureters Causing Urinary Incontinence in Dogs

Ectopic Ureters Causing Urinary Incontinence in Dogs


When Sam noticed that his young and energetic dog, Daisy, had begun leaving little puddles of urine around the house, he knew something wasn’t quite right. As a responsible pet owner, Sam took Daisy to the vet for a thorough examination, only to discover that she was suffering from urinary incontinence caused by ectopic ureters.

Ectopic ureters in dogs can cause urinary incontinence due to the abnormal positioning of the ureters, which are the tubes that transport urine from the kidneys to the bladder. Normally, these ureters enter the bladder at a specific location, allowing for proper urine storage and controlled release. The muscle at the bladder’s exit, the urethral sphincter, further aids in the storage and controlled release of urine. When the ureters are positioned correctly, and the sphincter functions as it should, dogs can hold their urine until they consciously release it.

However, when a dog has ectopic ureters, these ureters bypass the proper entrance to the bladder and enter elsewhere, such as directly into the urethra or vagina, in female dogs. This misplacement means that the urine may not be stored properly in the bladder and can leak out involuntarily, resulting in urinary incontinence. This issue might be continuous, with the dog dribbling urine all the time, or it may only occur when the dog is relaxed.

The ectopic ureters can also cause issues with the functioning of the urethral sphincter. In some cases, the abnormally placed ureters can interfere with the sphincter’s ability to close completely, further contributing to the problem of urinary incontinence.

It’s worth noting that urinary incontinence can lead to secondary issues like skin irritations or infections due to constant wetness and urinary tract infections due to abnormal urine flow. Therefore, addressing ectopic ureters promptly is crucial to prevent these secondary problems.

Causes of Urinary Incontinence in Dogs

Ectopic ureters are a congenital condition, meaning the abnormality is present when a puppy is born. The term “ectopic” refers to something that is out of place, and in this instance, it describes the ureters’ failure to properly connect to the bladder, which is their normal position. Instead, they incorrectly link to a different part of the urinary tract.

The foremost cause of this condition remains unknown, yet two theories predominate.


Certain dog breeds, such as Labrador Retrievers, Golden Retrievers, Siberian Huskies, and Bulldog breeds, show a higher incidence of ectopic ureters, suggesting a genetic predisposition. The condition also seems to affect females more than males.

Developmental Errors

An error during the developmental stage in the womb may result in this abnormality. The ureters, the tubes carrying urine from the kidneys to the bladder, may fail to enter the bladder correctly. Instead, they may connect to the urethra or even the vagina in female dogs, leading to constant urine leakage.

Anatomical Differences

There are instances where the ureters do not connect correctly. In some cases, only one ureter may improperly attach, known as a unilateral ectopic ureter, while in others, both ureters may misposition, known as bilateral ectopic ureters. This mispositioning can lead to continuous dribbling of urine since it bypasses the bladder entirely.

A veterinarian may suspect an ectopic ureter when a dog presents symptoms like continuous urine leakage, especially if it’s a young female dog of a predisposed breed. Further diagnostic tests are necessary to confirm the condition. When a diagnosis of ectopic ureters is made, the veterinarian will discuss the most appropriate treatment strategies. Treatment should be personalized, considering factors such as the dog’s age, overall health, breed, and severity of the condition. It’s important to remember that every dog is unique, and what works for one may not work for another.

Diagnosis and Treatment for Ectopic Incontinence

Diagnosing ectopic ureters in dogs usually involves several steps. Initially, your veterinarian may take a urine sample for a urine culture to check for infections causing inappropriate urination. A thorough physical examination is conducted, especially focusing on the urinary system.

Advanced diagnostic tools like abdominal ultrasound, computed tomography (CT), and cystoscopy, a procedure involving a camera on the end of a flexible tube inserted into the urethra, are often utilized. These tests are critical for visualizing the ureters and where they enter the bladder. Ectopic ureters, which continue inside the bladder, are rare, but the ureteral opening can be abnormally positioned.

Treatment for ectopic ureters is usually surgical, specifically soft tissue surgery, to correct the anatomical abnormalities where the ureters do not connect properly to the bladder. This surgery often requires general anesthesia. Post-surgery, the dog’s urinary continence often improves, although some dogs with severe urge incontinence may require additional treatment to remain fully continent.

Remember, although the kidney and ureter are related, the management of ectopic ureters focuses on correcting where the ureters enter the bladder. Approximately 50% of dogs with an ectopic ureter will not experience incontinence after proper treatment. A professional should always carry out these procedures to ensure the best outcome, as ectopic ureters are complex.

Prognosis of Urinary Incontinence in Dogs 1

Prognosis of Urinary Incontinence in Dogs

Urinary incontinence due to ectopic ureters can be a challenging condition to manage. Still, with appropriate treatment, many dogs can have a positive prognosis and live a normal, high-quality life.

The prognosis for dogs treated with surgery or laser ablation for ectopic ureters generally depends on the severity of the condition, the dog’s overall health, and any concurrent health issues. Some dogs may become completely continent following treatment, while others may have improved but not entirely resolved incontinence. Factors such as the presence of urinary tract infections, the dog’s age at diagnosis, and the specific anatomical configuration of the ectopic ureter can all impact the prognosis.

While surgical correction or laser ablation can significantly improve or even resolve urinary incontinence in many cases, it’s important to note that some dogs may have some degree of incontinence even after treatment. This is particularly true if there’s damage to the urinary sphincter or the dog has other concurrent conditions affecting the urinary tract.

Medical management can also be beneficial, particularly in dogs with mild incontinence. However, it’s not a cure and requires ongoing treatment and regular vet check-ups to manage the condition effectively.

Frequently Asked Questions

The sudden onset of incontinence in dogs can have various underlying causes. It may be due to urinary tract infections, bladder stones, hormonal imbalances, neurological disorders, or weakened sphincter muscles. Additionally, certain medications or age-related changes can contribute to incontinence. It is essential to consult with a veterinarian to determine the specific cause of your dog’s incontinence through a thorough examination, diagnostic tests, and medical history review. Once the underlying cause is identified, appropriate treatment can be implemented to manage or resolve the incontinence.

If an ectopic ureter is left untreated in dogs, it can lead to persistent urinary incontinence, urinary tract infections, kidney damage, and progressive deterioration of renal function. Ectopic ureter is a condition where the ureter, a tube carrying urine from the kidney to the bladder, does not connect properly. This leads to urine bypassing the bladder and causing involuntary leakage.

Early diagnosis and intervention are crucial for the best outcomes. Treatment options for ectopic ureters include surgery, such as repositioning the ureter or creating a new pathway to the bladder to restore normal urine flow.

The cost of fixing an ectopic ureter in a puppy can vary depending on factors such as the geographical location, the severity of the condition, the required diagnostic tests, surgical techniques, and the specific veterinary clinic. The surgical treatment of ectopic ureters usually involves specialized procedures and expertise. Therefore, consulting with a veterinarian or veterinary specialist who can assess your puppy’s condition and estimate the associated costs is recommended. They can provide a more accurate cost estimate based on your puppy’s needs.

Yes, dogs can recover from incontinence depending on the underlying cause and appropriate treatment. Incontinence can be managed or resolved with various treatment options, including medications, dietary changes, hormone therapy, behavioral modifications, or surgical interventions. The success of treatment and recovery depends on identifying and addressing the specific cause of the incontinence. Working closely with a veterinarian to determine the underlying cause and develop a tailored treatment plan to improve or resolve the incontinence symptoms is important.

Ectopic ureter is a relatively rare condition in dogs, primarily affecting female dogs, especially certain breeds such as Labrador Retrievers and Siberian Huskies. It is considered a congenital abnormality where the ureter does not properly connect to the bladder. The prevalence and incidence of ectopic ureter can vary depending on the breed, genetic factors, and other predisposing factors. Suppose you suspect that your dog may have an ectopic ureter or is experiencing urinary incontinence. Consulting with a veterinarian for a proper diagnosis and appropriate treatment is important.

Ureteroscopy is a minimally invasive procedure used to diagnose and treat conditions involving the ureters, which are tubes connecting the kidneys to the bladder. While ureteroscopy is not typically associated with causing incontinence, complications can occur in rare cases. Potential complications of ureteroscopy include injury to the ureters, bladder, or surrounding structures, which could lead to urinary leakage or incontinence.

However, with proper technique and experienced veterinary care, the risks of complications during ureteroscopy are minimized. It is important to discuss any potential risks or concerns with your veterinarian before undergoing the procedure.

There are several possible reasons for a dog to become incontinent of urine suddenly. It could be due to urinary tract infections, bladder stones, bladder tumors, hormonal imbalances, spinal cord injuries, or weakened sphincter muscles. Certain medications or age-related changes, such as cognitive dysfunction, can also contribute to incontinence. A thorough veterinary examination, including diagnostic tests such as urine analysis and imaging, can help determine the underlying cause. Once the cause is identified, appropriate treatment can be recommended to address the incontinence and improve your dog’s quality of life.

Ureter peristalsis refers to the rhythmic contractions of the muscles in the ureter that help propel urine from the kidneys to the bladder. These contractions are essential for normal urine flow. The exact mechanism of ureter peristalsis is complex and involves coordinating smooth muscle cells and nerve impulses. Abnormalities in the structure or function of the ureter can disrupt normal peristalsis and lead to urinary flow abnormalities. Conditions such as ectopic ureter or ureteral strictures can affect ureter peristalsis in dogs.

The success of ectopic ureter surgery in dogs depends on various factors, including the severity of the condition, the age and overall health of the dog, and the expertise of the veterinary surgeon. Ectopic ureter surgery in dogs aims to reposition the ureter or create a new pathway to the bladder, allowing normal urine flow. Surgery success rates can vary, but most dogs generally experience improvement or resolution of their symptoms following surgical intervention.

However, it is important to note that the success of surgery also depends on early detection and intervention. Delayed or advanced cases may have a lower success rate. It is recommended to consult with a veterinary specialist experienced in urogenital surgeries to assess the specific case and provide a more accurate prognosis for the success of ectopic ureter surgery in your dog.

If you have concerns or questions about your dog’s urinary issue or any other health condition, it is best to contact a veterinarian for professional advice. They can evaluate your dog’s specific situation, provide a diagnosis, and recommend appropriate treatment options. A veterinarian is the most qualified person to assess and address your dog’s health concerns and can provide guidance based on their expertise and experience. Contact your local veterinary clinic to schedule an appointment or seek advice from a veterinary professional through telemedicine platforms if available in your area.

The prognosis for dogs with ectopic ureters can vary depending on several factors, including the severity of the condition, the presence of concurrent abnormalities, the age of the dog, and the promptness of diagnosis and treatment. Early detection and appropriate surgical intervention can lead to a good prognosis, with many dogs experiencing improved urinary function and resolution of clinical signs.

However, the prognosis may be guarded in more severe or complicated cases, and long-term management or additional interventions may be necessary. It is crucial to consult with a veterinary specialist experienced in urogenital surgeries to assess your dog’s specific case and provide an accurate prognosis based on the individual circumstances.
