    Polyglycolic acid (PGA) sutures yielded the best results for canine ureter anastomosis, showing superior outcomes compared to catgut. This study evaluated suture materials for their long-term effects on ureter healing.

    Area of Science:

    • Veterinary Surgery
    • Surgical Materials Science

    Background:

    • Ureteral anastomosis is a critical surgical procedure in veterinary medicine.
    • The choice of suture material can significantly impact surgical outcomes and long-term healing.
    • Evaluating different suture types is essential for optimizing surgical techniques.

    Purpose of the Study:

    • To compare the efficacy of four different suture materials for end-to-end ureter anastomosis in dogs.
    • To assess the long-term effects of chromic catgut, polyglycolic acid (PGA), polyglactin-910, and polypropylene sutures on ureter healing.

    Main Methods:

    • Canine ureters were anastomosed using four distinct suture materials: chromic catgut, PGA, polyglactin-910, and polypropylene.
    • Histopathological analysis was performed at four and seven months post-surgery.

  • Evaluated parameters included luminal diameter, fibrosis, scar vascularity, and inflammatory response.

    • Main Results:

    • Polyglycolic acid (PGA) sutures demonstrated the best overall results in uninfected dogs.
    • Ureters anastomosed with PGA showed favorable luminal diameters, minimal fibrosis, and reduced inflammation.
    • Catgut sutures resulted in slightly less acceptable outcomes compared to PGA.

    Conclusions:

    • Polyglycolic acid (PGA) is a highly effective suture material for canine ureter anastomosis.
    • Suture material selection plays a crucial role in minimizing complications and promoting optimal ureter healing.
    • Further research may explore other synthetic absorbable sutures for ureteral reconstruction.
