Plain-English summary
In a study of seven horses diagnosed with pyelonephritis (a kidney infection), all were admitted because they were found to have blood in their urine. During examinations, five of the horses showed bleeding from their ureters, which are tubes that carry urine from the kidneys to the bladder. Tests like kidney biopsies and ultrasounds confirmed that the kidney infection was causing the bleeding. While the bleeding eventually stopped in all the horses, it came back in four of the five horses that were monitored over a longer period.
Abstract
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.
