Study highlights scissor-based option for canine ectopic ureters

Version 1

A new retrospective study in the Journal of Small Animal Practice reports favorable outcomes for 25 dogs treated for intramural ureteral ectopia using a modified cystoscopic-guided scissor transection technique, a minimally invasive alternative to laser ablation. According to the study abstract, median continence scores improved from 1/5 before surgery to 5/5 after surgery, with low complication rates. That matters because intramural ectopic ureters are the most common form of ureteral ectopia in dogs and a leading cause of urinary incontinence in young dogs, especially females.

Why it matters: For veterinary professionals, the report adds to a growing body of evidence that minimally invasive correction can deliver meaningful continence improvement while avoiding some of the access, cost, and equipment constraints tied to laser-based procedures. Prior studies of cystoscopic-guided laser ablation in female dogs found overall continence rates of 67.7% with or without adjunctive medical management, and broader literature has shown postoperative continence outcomes after ectopic ureter correction can vary widely. This new scissor-based series suggests another endoscopic option may be clinically useful where laser platforms aren't available, though persistent incontinence and the need for adjunctive medical management remain familiar issues in this case population.

What to watch: Watch for the full paper’s detailed breakdown of complications, case selection, and whether outcomes hold up against established laser-ablation series in longer-term follow-up. (pubmed.ncbi.nlm.nih.gov)
