Plain-English summary
A 19-year-old Hanoverian gelding had a kidney stone that needed to be surgically removed. The horse showed signs of straining and difficulty urinating, and a stone was found in the urethra, which was removed through a small surgical opening. The kidney stone was then taken out using a special camera inserted through this opening, and both procedures were done over two days while the horse was sedated but standing. After the surgery, the horse recovered well without any complications and was back to normal activities in two weeks, with no further urinary problems noted seven months later. Overall, the surgery was successful and helped keep the kidney functioning properly.
Abstract
OBJECTIVE: To describe the ureteropyeloscopic removal of a nephrolith in a horse. ANIMALS: A 19 year old Hanoverian gelding with history of urolithiasis requiring surgical intervention. STUDY DESIGN: 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. CONCLUSION: 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.
