CISTOTOMIA EM CADELA COM HIDRONEFROSE ASSOCIADA A OBSTRUÇÃO POR URÓLITOS VESICAIS: RELATO DE CASO

Urolithiasis is one of the most common diseases of the canine urinary system, which can be caused by diet, reduced water consumption by the animal, in addition to racial, age and sex predisposition. Furthermore, urolithiasis can culminate in hydronephrosis, in which the renal pelvis dilates as a result of the obstruction of urinary flow. The clinical signs of this condition vary according to the severity of the animal’s condition, but may include dysuria, polyuria and urinary incontinence. The definitive diagnosis is based on history, clinical evaluation, complementary imaging exams such as abdominal ultrasound and abdominal radiography. Treatment can be clinical or surgical and dietary management may be necessary, depending on the urinary stone analysis made. The objective of this report was to describe the clinical signs, diagnosis, treatment and prognosis of a five-year-old Shitzu female dog, with bladder uroliths and hydronephrosis as a result of this condition. After care and clinical management with laboratory and complementary exams, the treatment through cystotomy was the one of choice. The urolith was sent for analysis and allowed the establishment of an appropriate therapeutic protocol, through dietary management. Besides that, the female dog was monitored to observe the reversal of hydronephrosis. After surgical and clinical treatment, the animal presented a stable condition and the dilation of the renal pelvises were reversed, making the animal’s prognosis favorable.
