At least half of women have experienced the discomfort with urination caused by a urinary tract infection: painful, urgent, or frequent urination. Pyelonephritis may start with similar symptoms. However, once the infection has spread to the kidney, signs of more severe illness usually result.
The fact that pyelonephritis is usually ascending and bilateral suggests that these virulence factors are more important than previously recognized. Animals with acute pyelonephritis may exhibit kidney or flank pain, fever, malaise, and sometimes vomiting, polyuria, and polydipsia. Urinalysis shows proteinuria, pyuria, bacteriuria, and/or hematuria. WBC casts may be present in fresh urine sediment.
