Pionefrosis Secundaria A Litiasis Ureteral Izquierda Obstructiva En Canino. Reporte De Caso.

Abstract

Pyonephrosis in canines is a condition in which the kidney fills with pus due to a severe urinary tract infection that obstructs urine flow. This purulent accumulation causes progressive destruction of kidney tissue and requires surgical treatment, usually by ureteronephrectomy, nephrectomy, or ureteral bypass. Ureteronephrectomy is a surgical procedure that involves the removal of a kidney. It is performed due to an infection that compromises a large portion of the kidney tissue; in this case, the left kidney. We present the case of a 5-year-old canine admitted to the Pet Home veterinary clinic with signs of vomiting, fever, weakness, and loss of appetite. During the animal's clinical examination, physiological vital signs were found within the normal range, abdominal pain was noted on palpation, and diagnostic ultrasound and radiography were performed, revealing findings consistent with unilateral left ureterolithiasis and ipsilateral nephromegaly. The complete blood count revealed leukocytosis with anemia. Blood chemistry results showed parameters within range, except for elevated total protein and globulin levels. The patient was hospitalized for stabilization, and once the goal was achieved (infection control, anemia control), surgery was performed. A left ureteronephrectomy was performed, followed by an ovariohysterectomy due to left ovary involvement (perirenal peritoneal inflammation affecting the left ovary).
