Abnormal Urine Outflow Due to Urinary Bladder Dysfunction in Dogs

Vesicourachal Diverticula in Dogs

Vesicourachal diverticula is a congenital condition where the urachus, an embryological canal linking the placenta with the fetus’s urinary bladder, does not close properly. This malfunction affects the normal flow of urine in the animal, increasing its vulnerability to urinary tract infections. Without appropriate treatment, the condition can endure indefinitely.

Symptoms and Types

  • Blood in urine (hematuria)
  • Difficult urination (dysuria)
  • Increased frequency of urination (pollakiuria)


Vesicourachal diverticula frequently manifest either in utero or during the birthing process. Nonetheless, there exists an acquired variant of the condition, stemming from illnesses that exert excessive pressure on the bladder (such as bacterial urinary tract infections, uroliths, and urethral plugs). There is no predisposition based on breed or age for vesicourachal diverticula.


A comprehensive history of your dog’s health, detailing the onset and characteristics of symptoms, is essential. The veterinarian will perform a thorough physical examination, along with a biochemistry profile, urinalysis, and complete blood count (CBC), all of which aid in pinpointing the underlying cause of the condition and detecting any concurrent disorders.

However, the most effective diagnostic tool is X-rays of the urethra and bladder utilizing contrast medium to confirm the diagnosis.


The treatment plan will be determined based on the underlying cause of vesicourachal diverticula. Dogs that do not respond to standard treatment methods may necessitate surgical intervention to address the defect.

Living and Management

Regular follow-up examinations with the veterinarian are necessary, during which urine samples will be collected to assess the status of infection. Certain animals may require prolonged antibiotic therapy to manage urinary tract infections. However, the overall prognosis for dogs with vesicourachal diverticula is favorable following treatment.
