Advancing Feline Ureteral Surgery: Updates on Unilateral Proximal Obstruction Management and a Proposed Strategy for Bilateral Proximal Obstructions

Feline ureteral obstruction is commonly found in the proximal ureter. While ureterotomy is a viable option for ureterolith-associated obstructions in this region, it is not indicated for other causes, such as strictures, trauma, iatrogenic ligation, or neoplasia. In such cases, surgical intervention can be challenging and requires careful selection of surgical options. This lecture provides an in-depth overview of the surgical techniques we employ for managing unilateral proximal ureteral obstructions, particularly those near the ureteropelvic junction, including procedural steps, technical considerations, and key intraoperative challenges. Additionally, this lecture presents clinical outcomes based on our clinical experience, offering valuable insights into the efficacy and limitations of these techniques. Furthermore, the lecture introduces a strategic approach to bilateral proximal obstructions, a condition with scarce published data and limited surgical guidance. By sharing clinical outcomes and surgical insights, this lecture aims to lay the groundwork for improving treatment strategies and fostering discussion on potential advancements in ureteral surgery. Attendees gain practical knowledge of available surgical techniques, their indications, and expected outcomes. This lecture aims to inspire new perspectives on feline ureteral surgery, encouraging further refinement of surgical approaches to enhance patient care.
