Pseudomembranous cystitis of a feline

Resumo

Feline pseudomembranous cystitis is a disease characterized by the presence of false membranes forming intravesical septa, adhered or not to the lumen, causing compartmentalization due to the accumulation of necrotic cell debris, fibrin, blood, and inflammatory cells, in addition to severe thickening of the wall and severe inflammation in the organ. Diagnosis is made mainly through ultrasound examination associated with histopathological examination, which aids in a more accurate diagnosis. Treatment is individualized for each patient; unblocking by catheterization, relief cystocentesis, and bladder lavage stabilizes the patient for the performance of the surgical procedure of cystostomy, which ends up being recurrently indicated to resolve the condition, associated with environmental management in the post-surgical period so that there are no recurrences of cystitis. This report describes a case of a feline diagnosed with pseudomembranous cystitis. The animal was treated for stranguria, dysuria, hematuria, pollakiuria and periuria. The ultrasound imaging revealed a thickened bladder and echogenic content forming pseudomembranes in the intraluminal space. The animal was referred for cystotomy surgery, where hemorrhagic and necrotic content was observed inside the bladder. A biopsy was taken of fragments of the bladder and its contents. Histopathological examination revealed necrohemorrhagic cystitis.
