Ureteropyelonephritis in a Friesian mare.

The research article presents a case study of a 14-year-old Friesian breeding mare diagnosed with pyelonephritis, a urinary tract infection that extended to the horse’s kidneys and ureters, potentially caused by small tumors in the vulva.

Introduction

The research article discusses a severe case of ureteropyelonephritis, a urinary tract infection affecting the kidney and ureter, in a 14-year-old Friesian mare. This condition resulted in the mare exhibiting several symptoms, including strangury, depression, inappetence, neutrophilia, and uraemia. It was suggested that small tumors present in the mare’s vulva may have been the cause for this condition.

Observations and Findings

• When the mare’s urine was examined, it indicated a low specific gravity and contained elements such as protein, blood cells, and bacteria. These findings are indicative of an infection in the urinary system.
• A rectal examination of the mare revealed both its kidneys and ureters were enlarged, suggesting the infection had extended to these organs.
• Other observable symptoms included strangury (difficult or painful urination), depression, loss of appetite (inappetence), increase in the number of neutrophils (neutrophilia), and high levels of urea in the blood (uraemia). All these are typical symptoms of a urinary tract infection that has spread to the kidney (pyelonephritis).

Post-Mortem Examination

• A post-mortem examination was performed on the mare, confirming the diagnosis of pyelonephritis.
• Additionally, the examination revealed the presence of small tumors in the vulva. As the vulva is in close proximity to the urogenital system, it is highly plausible that these tumors could have been the source of the infection that ultimately led to pyelonephritis.

Conclusion

The research provides a detailed case study of pyelonephritis in a Friesian mare, with tumors in the vulva being suggested as the possible cause. The severity of the condition, as evident from the symptoms and eventual death of the mare, highlights the need for early detection and treatment of urogenital conditions in equine health management.
