Ectopic Ureter
Ectopic ureters are a congenital defect where one or both ureters connect to the wrong location (urethra, vagina, colon, or uterus) instead of the bladder, causing urinary incontinence.
Key Facts
- Most patients are female puppies under 1 year with urinary leaking
- 64% have concurrent bladder infection
- Diagnosis: IV pyelogram (60-70% accuracy), ultrasound, CT scan (most accurate), cystoscopy
- Surgical correction: neoureterostomy or neoureterocystostomy depending on anatomy
- Laser ablation via cystoscope: less invasive, better continence outcomes
- 33-58% achieve full continence resolution after surgery; 55% show improvement
- Many patients need ongoing incontinence medication even after anatomical correction
- Multiple internal urinary anatomical abnormalities often coexist
- Species: dogs (primarily)
