Severe renal hemorrhage caused by pyelonephritis in 7 horses: Clinical and ultrasonographic evaluation

Case records of 7 horses diagnosed with pyelonephritis were reviewed to determine common features that might aid in diagnosis, treatment, and prognosis of this disease. All 7 horses had been admitted for evaluation of hematuria. During cystoscopy of 5 horses, hemorrhage was observed from one or both...

Description
Summary:Case records of 7 horses diagnosed with pyelonephritis were reviewed to determine common features that might aid in diagnosis, treatment, and prognosis of this disease. All 7 horses had been admitted for evaluation of hematuria. During cystoscopy of 5 horses, hemorrhage was observed from one or both ureters. Renal biopsy of 1 horse, laboratory analysis of ureteral discharge of 2 horses, and renal ultrasonography of all horses indicated that pyelonephritis was the cause of hemorrhage. Sonographic renal changes included decreased length, increased echogenicity, abnormal outline, loss of corticomedullary distinction, pyelectasia, and focal hypoechoic or hyperechoic cortical defects. Renal hemorrhage in all horses eventually resolved but recurred in 4 of 5 horses that were followed long-term.
