NEFRECTOMIA UNILATERAL EM CADELA ACOMETIDA POR HIDRONEFROSE: RELATO DE CASO

Abstract

Hydronephrosis is a consequence of urinary flow obstruction and is characterized by dilation of the renal pelvis, which may have congenital or acquired origin. This obstruction can be presented in a partial or complete form, thus leading to atrophy by compression of the renal parenchyma and cystic dilatation. The most common causes of renal obstruction observed are: constriction of the ureter by abdominal masses, ureteral stones, ureter scars, neoplasia in the bladder trigone or accidental ligation during surgical procedures, neurogenic bladder functional disorder, among others. The objective of this work is to report a clinical case of hydronephrosis in a 6-year-old female French Bulldog, which culminated in a right unilateral nephrectomy. The bitch had a distended abdomen and hematuria. Laboratory tests showed changes in urea and creatinine, the other tests were normal. During the surgery, it was noticed that there was a mass adhered to the right kidney. There was no free abdominal fluid or signs of peritoneal and/or retroperitoneal inflammation. Finally, it is concluded that nephrectomy was of paramount importance in this case, since the kidney had already lost its conformation and function Loss of renal parenchyma, replaced by exuberant fibrocollagenous tissue was verified microscopically. The underlying cause of hydronephrosis has not been clarified.
