“…Some studies also reported that macroscopic diverticula may develop from microscopic diverticula, with the concomitant presence of disorders of the lower urinary tract, such as bacterial infections, urolithiasis, urethral plugs, sediment, or idiopathic cystitis. However, the exact relationship between vesicourachal diverticula and other disorders of the lower urinary tract is still unknown [ 4 , 27 , 28 , 29 , 30 ].…”

This retrospective study investigated the prevalence of different urachal anomalies (UA) in cats (n = 60) and dogs (n = 38) and their association with clinical symptoms and urinalysis alterations. Among UA, the vesicourachal diverticulum was the most prevalent UA diagnosed in both cats (96.7%) and dogs (89.5%): the intramural vesicourachal diverticulum was diagnosed in 76.7% of cats and 71.1% of dogs, followed by extramural vesicourachal diverticulum (20.0% and 18.4% respectively). In both cats and dogs, bladder wall diffuse or regional thickening was the most prevalent alteration. The most common alterations of the urinary bladder content were urolithiasis sediment in cats (33.3%) and in dogs (31.6%). Dogs with UA were more often asymptomatic (p = 0.01). No difference was found in cats. Stranguria, hematuria, and urethral obstruction were the most frequently reported clinical signs, while hematuria and leukocyturia were the most prevalent abnormalities at urinalysis. In conclusion, our study confirmed UA as uncommon, and often incidental findings, with a high prevalence of animals without clinical signs.

“…Dogs with lower urinary tract disease are often associated predisposing factors like anatomic anomalies, neoplasia, polyps, uroliths, pyelonephritis, prostatitis, ureterocele and urachus remnant, endocrine diseases, and immunosuppression (Visser et al, 2020). Bladder tumours represent 2% of cancer in dogs, and 90% of those tumours are malignant tumours and epithelial tumours.…”

In canines, when a mass in the bladder is observed by ultrasonography, a malignant tumor is a presumptive diagnosis. In humans, it is common in the presence of clots due to uncontrolled hematuria. We describe the case of a 7-year-old male mixed breed dog, with a clinical history of hematuria 6 months and presence of ticks. Ultrasound studies of the bladder were performed for one month. The evaluations showed a mass in the bladder trigone, covering 80% of the bladder lumen without acoustic shadow, and then a cystectomy was performed. An oval mass was found with irregular borders and clotted blood appearance, with not adherent to the bladder tissue. The histological diagnosis of the mass showed erythrocytes and polymorphonuclear inflammatory cells: neutrophils and mononuclear cells such as macrophages, mixed with moderate fibrin threads compatible with a bladder clot. Therefore, the diagnosis was a benign mass and not a transitional cell carcinoma as usual. Masses found in the bladder are not necessarily a neoplastic proliferation.
