A Rare Case of Urogenital, Pelvic, and Tail Duplication in a Dog.

We describe a case of congenital duplication involving urogenital organs, pelvis and tail in a dog diagnosed by ultrasound scanning, retrograde urethrocystography, and excretory urography. Left nephrectomy, cystectomy, urethral resection, orchidectomy, penectomy, and caudectomy were the treatment options for this case. No spine or intestinal alteration was observed by radiography. After the surgery, the patient condition was assessed for one year. No significant changes were observed in ambulation or in laboratory test results during this period, including normal urination. The patient is currently 6 years old, and is in good condition and with quality of life.
