Ureteropyeloscopic removal of a nephrolith from a 19 year old Hanoverian gelding.

Abstract: To describe the ureteropyeloscopic removal of a nephrolith in a horse. Methods: A 19 year old Hanoverian gelding with history of urolithiasis requiring surgical intervention. Methods: Case report METHODS: The horse presented with signs of abdominal straining and stranguria. A proximal urethral calculus was palpable externally within the perineal urethra. Perineal urethrostomy (PU) at the location of the urethral calculi was performed to remove the urethral obstruction. Left nephrolithiasis was then treated by endoscopic retrieval, inserting the endoscope through the PU. The procedures were performed over 2 consecutive days, with the horse standing and sedated. Medical therapy included antimicrobial and anti-inflammatory treatment. Results: The ureteropyeloscopic removal of a nephrolith from the left renal pelvis was completed. No complications were appreciated following the procedure, and the horse was able to return to athletic activity within 2 weeks. The horse had no further clinical signs referable to urinary dysfunction 7 months later. Conclusions: Ureteropyeloscopic removal of a nephrolith from the renal pelvis is technically feasible in the equine patient and preserves function of the affected kidney. The availability of a treatment that maintains renal function is a distinct benefit over unilateral nephrectomy, particularly when treating a condition that frequently involves both kidneys.

The research presents a case of a horse successfully treated for a kidney stone using ureteropyeloscopy, a minimally invasive procedure, explaining that it preserves the kidney function and allows quicker recovery for the horse.

Background and Methods

  • The paper addresses a case of a 19-year-old Hanoverian gelding, a horse breed, which had a history of urolithiasis – a condition where stones are formed in the urinary tract that require surgical intervention.
  • The horse exhibited signs of abdominal straining and stranguria – a condition where urination is slow and painful. An initial examination revealed a calculus (stone) located in the urethra, which was externally detectable.
  • To treat this, the researchers performed a Perineal Urethrostomy (PU) at the location of the urethral calculi – a surgical procedure that creates an opening in the urethra to facilitate urine passage. This process successfully removed the obstruction in the urethra.

Procedure Execution

  • Subsequently, the horse was diagnosed with a condition, nephrolithiasis, in the left kidney. Nephrolithiasis is the formation of kidney stones.
  • The researchers addressed this by doing an endoscopic retrieval, which involves the insertion of an endoscope (a long, thin tube with a light and camera at the tip) through the opening created via the PU operation, allowing the surgeon to visualise and extract the kidney stone.
  • The entire procedure happened over two days, with the horse being in a standing state and under sedation.
  • Medical therapy included the use of antimicrobial and anti-inflammatory treatment to help prevent infection and inflammation after the surgery.

Results and Conclusion

  • The procedure proved to be successful, removing the kidney stone with no complications being noticed after the process.
  • The horse was able to get back to its athletic activities within two weeks. There were no symptoms of urinary dysfunction seven months post-procedure.
  • Ureteropyeloscopic removal of a kidney stone from the renal pelvis in a horse was therefore deemed technically achievable.
  • Importantly, this approach maintains the function of the kidney, which is a substantial benefit considering the standard alternative – unilateral nephrectomy (surgery to remove one kidney) – which could pose a significant challenge, especially in conditions that frequently affect both kidneys.
