An adult female dachshund presented with urinary incontinence and chronic intermittent urinary tract infections present since time of ovariohysterectomy two years prior. Ultrasonic examination and CT imaging diagnosed unilateral hydronephrosis, hydroureter and suspected communication between the right ureter and the uterine stump. There was no detectable renal dysfunction on serum biochemistry and urinalysis. A neoureterocystostomy was performed using an intravesical technique. The dog was discharged 48 hours postoperatively with complete resolution of clinical signs.
