Megaureter and hydronephrosis by extramural ureteral ectopia in dog

Abstract

Ureteral ectopia is a congenital abnormality of the genito-urinary tract disorder characterized by the insertion of the ureter in the urinary bladder, the most common cause of urinary incontinence in young dogs, occurring predominantly in female animals. Anatomically it is classified as intramural or extramural. In the intramural ureter is attached to the dorsal surface of the urinary bladder, but has failed to culminate in the trigone, while the extramural there is a deviation in full bladder and can occur in both cases unilaterally or bilaterally. The main clinical signs include addition of urinary incontinence, vulvar eczema with hyperpigmentation, hypotrichosis and dermatitis in perivulvar region, hematuria, pyuria and recurrent cystitis. The objective of this article report the case of a bitch pinscher breed, 8 months old, attended at the Veterinary Hospital of UFPI, diagnosed and treated for ureteral ectopia with megaureter and acquired hydronephrosis.
