Summary
A five-year-old cow with chronic hematuria was diagnosed with unilateral pyelonephritis caused by Corynebacterium renale. Surgical removal of the affected kidney (nephrectomy) led to a successful recovery, highlighting surgical intervention for severe bovine kidney infections.
Area of Science:
- Veterinary Medicine
- Bovine Pathology
- Surgical Procedures in Cattle
Background:
- Chronic hematuria in cattle can indicate serious underlying kidney pathology.
- Pyelonephritis, an infection of the kidney, poses a significant health risk to livestock.
- Accurate diagnosis is crucial for effective treatment of bovine urinary tract diseases.
Observation:
- A five-year-old Eringer cow presented with chronic hematuria.
- Diagnostic procedures including ultrasonography, endoscopy, and urinalysis confirmed unilateral pyelonephritis of the right kidney.
- The causative agent was identified as Corynebacterium renale.
Findings:
- Standard antimicrobial therapy with procaine penicillin proved ineffective against the infection.
- Nephrectomy (surgical removal of the kidney) was successfully performed on the standing animal via a right flank approach.
- Post-operative follow-up at ten months showed the cow in normal general health.
Implications:
- Surgical intervention, such as nephrectomy, can be a viable and effective treatment option for unilateral pyelonephritis in cattle when medical treatment fails.
- This case underscores the importance of considering surgical options for refractory bovine kidney infections.
- Further discussion on the etiopathogenesis, diagnostics, and therapeutics of pyelonephritis in cattle is warranted.
