Plain-English summary
A 3-year-old Thoroughbred colt was taken to the vet because he was very tired and had stopped eating. The examination showed that he had a stone in his left ureter, which was blocking about 90% of his urine flow. Tests also indicated that his right kidney had some damage. To treat him, the vet gave him fluids and medications, and then used a special procedure to break up and remove the stone. After the surgery, the colt's kidney function improved, and he was able to go back to training.
Abstract
A 3-year-old Thoroughbred colt was presented for evaluation of azotemia and anorexia. Physical examination revealed a ureterolith in the left ureter, approximately 10 cm from the bladder, which was thought to obstruct urine flow by approximately 90% when viewed cystoscopically. Ultrasonographic examination of both kidneys revealed indistinct corticomedullary junctions, and the right kidney was more hyperechoic. A percutaneous biopsy of the right kidney revealed chronic interstitial nephritis with marked interstitial medullary fibrosis. Medical therapy consisting of IV fluids, sodium chloride PO, and ammonium chloride PO was initiated. Ureteroscopic electrohydraulic lithotripsy via a perineal urethrostomy was used to successfully remove the stone. Klebsiella oxytoca, which responded to oral enrofloxacin therapy, was cultured from the urine after surgery. Azotemia resolved and the horse resumed training.
