Subcutaneous Ureteral Bypass Device for Treatment of Ureteral Obstruction in Persian Breed Female Cat

Abstract

In the recent years, benign ureteral obstruction by nephrolithiasis has an increased incidence in the feline population, whose causes are not yet fully established. Its diagnosis is based on clinical signs, biochemical analyzes and imaging methods such as radiography and ultrasound. For its treatment, initially one can resort to pharmacological therapy. However, when this is ineffective or contraindicated due to the risk of deterioration of the renal condition, there is a need for surgical intervention. Currently, the subcutaneous ureteral bypass implantation technique is being used more frequently, despite the high cost and periodic mainitance of system functionally. In this case report, we describe the implantation of the subcutaneous ureteral bypass system in a 9-year-old Persian breed female cat with azotemia associated with total obstruction of the right ureter and partial obstruction of the left ureter by nephrolithiasis. In function of total obstruction of right ureter lumen and risk of total obstruction of left ureter lumen was decided by immediate surgery intervention with use of subcutaneous ureteral bypass system. After the implantation of the subcutaneous ureteral bypass system, there was disappearance of azotemia and improvement in the clinical picture and quality life of the cat female.
