Case records of 7 horses diagnosed with pyelonephritis were reviewed to det
ermine common features that might aid in diagnosis, treatment, and prognosi
s of this disease. All 7 horses had been admitted for evaluation of hematur
ia. During cystoscopy of 5 horses, hemorrhage was observed from one or both
ureters. Renal biopsy of 1 horse, laboratory analysis of ureteral discharg
e of 2 horses, and renal ultrasonography of all horses indicated that pyelo
nephritis was the cause of hemorrhage. Sonographic renal changes included d
ecreased length, increased echogenicity, abnormal outline, loss of corticom
edullary distinction, pyelectasia, and focal hypoechoic or hyperechoic cort
ical defects. Renal hemorrhage in all horses eventually resolved but recurr
ed in 4 of 5 horses that were followed long-term.
