Unilateral nephrolithiasis and uroliths in the urinary bladder in a Schnauzer dog

Abstract

In the urinary system of pet animals, urolithiasis is one of the most commonly encountered conditions. The diagnosis of urolithiasis can be confirmed through anamnesis, physical examination and complementary exams. The treatment of urinary stones can be clinical or surgical, and the treatment will vary depending on the composition of the urolith and its location. In the present report, we highlight a female dog, 8 years old, Schnauzer breed, not castrated. The tutor reports previous consultation, in a colleague, as a result of symptoms and changes in the locomotor activity of the referred animal. Complementary exams were carried out that found the presence of structures compatible with lithiasis in renal topography and in the urinary vesicle. Thus, a nephrotomy, cystotomy and ovary elective hysterectomy of the animal was performed, and after the surgical procedure, the animal was chosen to remain hospitalized for evaluation in the first 24 hours in order to monitor urine output and control pain. After 10 days of the surgical procedure, ultrasound was repeated, with no evidence of abnormalities. The tutor was instructed to perform exams periodically to reassess possible relapses and to continue administering the therapeutic ration for at least 3 months.
