Background: This work reports a case of urethral obstruction by urolith in a female cat. The patient had a history of hematuria beginning approximately 2 months before visiting the clinic, with anorexia, apathy, emesis, tenesmus and absence of urination. Following physical and ultrasonic examinations, urethral obstruction by urolith was diagnosed. Although feline lower urinary tract disease (FLUTD) is common in both males and females, a urethral obstruction in female cats is extremely rare. This report aims to alert veterinarians to such an occurrence, highlighting the importance of early diagnosis and treatment in view of the severity of the consequences of a urethral obstruction.Case: An undefined, female cat of indefinite age, with a history of hematuria, emaciation, anorexia, apathy, emesis, tenesmus and anuria, presented at our clinic. Physical examination revealed dehydration, discrete rectal prolapse and dysuria. During abdominal palpation, a rigid spherical-shaped structure was observed in the hypogastric region, and complementary examinations were subsequently performed. Hematological examination revealed leukocytosis and increased serum urea and creatinine levels. Abdominal ultrasound examination showed that the urinary vesicle was full, with heterogeneous anechoic content with discrete sedimentation, as well as the presence of a hyperechogenic structure that formed an acoustic shadow at the transition between the bladder trigone and the urethra. In addition, both renal pelves presented dilatation by anechoic content, and measured about 0.5 cm. Treatment with amoxicillin and potassium clavulanate (20 mg/kg administered intravenously) was initiated, and the patient was referred to undergo a surgical procedure to remove the calculus. When exploring the abdominal cavity, the urinary vesicle was identified, which appeared to be rigid.[...](AU)
