Abstract

This case report describes the use of computed tomography for the diagnosis and surgical planning in a horse with bilateral nephrolithiasis.

An adult Warmblood stallion (460 kg) was presented with chronic weight loss, hypercalcemia and azotemia. Ultrasonographic examination identified hyperechoic masses in both kidneys and dilation of the right renal pelvis. A solid mass was evident upon transrectal examination on the left side. Computed tomography (CT) of the caudal abdomen was performed and provided good quality images that facilitated exact determination of the size, position and extent of renal mineralization.

The nephrolith of the right kidney was better demarcated when compared to the one of the left kidney and was therefore selected for nephrotomy. The horse developed a surgical site infection that led to euthanasia 3 weeks post-surgery.

CT of the caudal abdomen in an adult horse is feasible and the three-dimensional understanding of renal mineralization provided a great advantage for the selection and planning of the most appropriate treatment option.

双侧肾结石温血种马的计算机断层扫描和肾切开术。

本病例报告描述了使用计算机断层扫描诊断和手术计划的马与双侧肾结石。一匹成年温血种马（460公斤）表现为慢性体重减轻、高钙血症和氮血症。超声检查发现双肾高回声肿块和右侧肾盂扩张。经直肠检查左侧可见一实性肿块。对尾腹进行CT检查，提供了高质量的图像，有助于准确确定肾矿化的大小、位置和范围。与左肾肾结石相比，右肾肾结石的界限更好，因此选择肾切除术。这匹马在手术后3周发生手术部位感染，导致安乐死。成年马尾腹CT检查是可行的，对肾矿化的三维了解为选择和规划最合适的治疗方案提供了很大的优势。
