Study highlights minimally invasive option for canine ureteral ectopia

CURRENT BRIEF VERSION: A new retrospective study in the Journal of Small Animal Practice reports favorable outcomes for 25 dogs treated for intramural ureteral ectopia with a minimally invasive modified cystoscopic-guided scissor transection technique. According to the study abstract provided, dogs had significant improvement in continence scores with low complication rates, positioning the approach as a potential alternative to cystoscopic laser ablation. That matters because intramural ectopic ureters are the most common form of ureteral ectopia in dogs and a frequent cause of lifelong urinary incontinence in young patients.

Why it matters: For veterinary professionals, the study adds to a small but growing body of evidence that scissor-based cystoscopic correction may be a practical minimally invasive option when laser equipment isn't available or when case selection favors a mechanical transection approach. Earlier published data in eight female dogs found immediate continence improvement in six of seven dogs with follow-up, with minor complications limited to transient lower urinary tract signs, and concluded the technique could be a safe, effective alternative in the absence of laser technology. Broader literature also suggests minimally invasive correction can reduce morbidity compared with open approaches, although many dogs still need adjunctive medical management for urethral sphincter mechanism incompetence after anatomic correction. That same minimally invasive trend is also showing up elsewhere in urinary tract surgery: a recent two-dog Veterinary Surgery case series reported successful laparoscopic stapled partial cystectomy with intraoperative cystourethroscopy for small solitary ventral-to-apical urothelial carcinomas, with no intraoperative or short-term complications and complete histologic excision in both dogs.

What to watch: The key next question is whether larger, comparative studies will show this modified scissor technique can match or outperform laser ablation on long-term continence, complication rates, procedure time, and equipment accessibility. More broadly, minimally invasive urinary surgery reports remain small, and newer techniques such as closed laparoscopic stapled cystectomy for selected bladder tumors will also need more data before their role is clear.
