Postoperative evaluation of renal function after surgical correction of a ureterovaginal fistula in a cat.

Unilateral hydronephrosis and urinary incontinence, secondary to a ureterovaginal fistula, were corrected in a cat after surgical excision of the fistula and implantation of the affected ureter into the bladder. Salvage of the kidney was attempted because underlying chronic bilateral renal disease was suspected. Renal scintigraphy was used to monitor improvement in the function of the previously obstructed kidney after surgery.
