RESUMEN
A 2-year-old Himalayan cat was examined because of 4 days of vomiting, lethargy; and anorexia. The cat had undergone hysterectomy and removal of left ovarian remnants 5 days earlier. Results of laboratory testing and excretory urography were consistent with uremia and bilateral ureteral obstruction. Nephrostomy catheters were placed to drain urine and allow time for physiologic diuresis prior to definitive repair. During the next 2 days, the cat's physiologic status improved greatly. The cat underwent exploratory surgery, and both ureters were found to be ligated. The healthy proximal portions of the ureters were implanted into the bladder. Six months after surgery, the cat was doing well, and excretory urography demonstrated that both ureters were patent. Bilateral obstruction of the ureters is a life-threatening condition that can be difficult to correct in cats. Placement of nephrostomy catheters allows time for improvement in the cat's physiologic status prior to the protracted anesthesia time needed for surgical repair of the ureters.

Collapse of the cervical portion of the trachea was diagnosed for 2 young large-breed dogs. Clinical signs included worsening respiratory stridor and coughing exacerbated by exercise. The diagnosis was confirmed by use of conventional radiography and fluoroscopy of the trachea. A polypropylene, spiral ring, extraluminal, tracheal prosthesis was used to successfully treat tracheal collapse in each dog. Although tracheal collapse typically affects middle-aged and old small-breed dogs, tracheal collapse should be considered as a differential diagnosis for large-breed dogs with a honking cough and respiratory stridor.
