Outcome of Case



This cat had his left kidney removed after 3 days
of medical management (IV fluids, potassium
supplementation and amitriptyline) were
unsuccessful in treating the ureterolith and
relieving his obstruction.
He also had a gastrotomy tube placed at the
time of surgery to provide post-op nuturition.
The cat was discharged four days following his
nephrectomy.
