Surgical correction of bilateral ectopic ureter using the neoureterocystostomy technique
Keywords:Genito-urinary disorders, Urinary incontinence, Ureter, Urinary vesicle
Ureteral ectopy is a rare disorder in the small animals’ clinic. It is characterized as a congenital anomaly, resulting from the ducts differentiation failure during embryogenesis. In this scenario, the ureters present themselves outside the anatomical site, being inserted into the uterus, urethra, urinary vesicle neck, or vagina. The clinical signs are urinary incontinence and perivulvar dermatitis. Surgery is the accepted treatment to correct the anomaly. The surgical procedure is based on relocating the ectopic ureter and treating associated modifications. This report describes a case of intramural bilateral ureteral ectopy, corrected surgically through the neoureterocystostomy technique, making it possible to control the animal’s urinary incontinence.
