Objective: To induce experimental vesicoureteral reflux in dogs.
Design: Experimental study.
Animals: A total of 16 mixed- breed Persian dogs with different sex. Procedure: All sixteen dogs evaluated for absence of congenital or acquired vesicoureteral reflux before study by cystography. Vesicoureteral reflux induction was attempted in healthy animals by ureteral unroofing (3-5 mm) without suture, unroofing (3-5 mm) with catheter as a cutting guide and suturing by silk, unroofing (3-5 mm) with catheter and suturing by nylon and unroofing (5-7 mm) with catheter and suturing by nylon. After ten days the reflux assessment was
confirmed by cystography.
i Statistical analysis: Descriptive study.
Results: Vesico ureteral induced refluxes in all four groups were variable (incision length, catheter as guide, Number and kind of suture material)but refluxes induced with 5-7 mm incision length and nylon suturing was excellent as compared
with other three groups.
Clinical implications: Cutting method with catheter and nylon suture material used for vesicoureteral reflux induction in dogs, were preferred with special attention to be made to
I the length of cutting and the number of suture needed.
