Diagnosis, medical and surgical treatment approaches of equine urolithiasis 2. - Case reports

SUMMARY In the second part of series of articles the authors present the clinical course of six equine urolithiasis cases. The horses were referred to the Equine Department and Clinic of the Veterinary Faculty of Szent Istvan University from 2007 to 2014 with pollakiuria, stranguria, haematuria or colic signs. Uroliths were detected via transrectal or percutaneous ultrasound, and following surgical removal, the stones were analysed for chemical composition. In each cases, uroliths predominantly consisted of calcium carbonate. In four cases, solitary large urolith was removed from the urinary bladder via ventral midline celiotomy and cystotomy under general anaesthesia. In the fi fth case standing perineal urethrotomy was carried out. The sixth horse showed recurrent acute colic and was subjected to midline laparotomy. Intraoperative fi nding revealed marked hydronephrosis of the left kidney and the horse was subsequently euthanised due to poor prognosis. Recurrence occurred in one case and a second cystotomy was performed. The authors’ intention is to share their experience through this case series and to provide insight into the commonly encountered clinical scenarios while managing equine urolithiasis
