Fluoroscopic Stent Placement for the Relief of Malignant Urethral Obstruction in a Cat

The clinical features and interventional therapy in the case of a female cat with urinary tract obstruction secondary to neoplasia are presented. This form of neoplasia in cats is rare and therapeutic intervention to relieve urinary tract obstruction caused by malignancy has been described only once. This is the first report of a self-expandable metallic stent placed in a feline urethra to relieve obstruction caused by malignancy and the first report of the use of a unique composite metallic stent (Platinol™) in a cat. In conclusion, the palliative stenting of the feline urethra may be a valid therapeutic intervention for malignancies. Further studies are required to determine the optimal size and type of stent that will provide the greatest benefit.
