Validation of a novel translumbar ultrasound technique for measuring renal dimensions in horses.
Abstract: A reliable method for obtaining renal ultrasonographic measurements in the horse is important for diagnosis and monitoring of clinical renal disease. The aims of this prospective study were to develop and validate a novel translumbar ultrasound technique for measuring renal dimensions in horses. Six Thoroughbred or Thoroughbred part bred horses were recruited. All horses were scheduled for euthanasia due to reasons unrelated to the kidneys. Two observers recorded renal length, width, and depth; and dimensions of the cortex, medulla, pyramids, and pelvis for both kidneys in each horse using novel translumbar and conventional transabdominal ultrasound methods. The same measurements were recorded from post-mortem renal specimens. Both kidneys were consistently identified by both methods in the 15-17th intercostal spaces and paralumbar fossa. Using the translumbar technique, maximal dimensions were obtained for the left kidney in the 16th intercostal space (length 16.2 ± 2.0 cm, width 11.8 ± 0.5 cm, depth 6.4 ± 0.9 cm) and for the right kidney in the 15th intercostal space (length 16.1 ± 1.2 cm, width 13.4 ± 1.2 cm, depth 6.7 ± 0.7 cm). Renal dimensions obtained by transabdominal and translumbar projections did not differ (P > 0.05). Good correlations were found between overall renal dimensions and post-mortem measurements for both ultrasound techniques (r(2) > 0.8), but were better for the translumbar method (mean r(2) = 0.92 cf. 0.88). Good-to-excellent reliability was found for all translumbar ultrasound measurements except for the renal cortex. Reproducibility was better for the larger (overall length, width, and depth) than the smaller (cortex, medulla, and pyramids) structures. Findings indicated that translumbar ultrasonography is a valid method for measuring renal dimensions in horses.

The study is focused on developing and validating a new ultrasound technique, the translumbar method, for accurately measuring kidney dimensions in horses. This is deemed important for diagnosing and monitoring clinical renal disease.
Objective of the Research
- The research aimed to develop and validate a new ultrasound method, known as the translumbar technique, to measure kidney dimensions in horses. This would assist in the diagnosis and the clinical management of renal diseases in these animals.
Methodology
- Six Thoroughbred or Thoroughbred part-bred horses were selected for the study, all of which were scheduled for euthanasia for reasons not related to kidney health.
- Two observers used both traditional transabdominal and the new translumbar ultrasound techniques to measure the renal length, width, and depth, along with the dimensions of the cortex, medulla, pyramids, and pelvis for both kidneys in each horse.
- These results were compared with measurements taken from post-mortem renal specimens to validate their accuracy.
Findings
- The two techniques, traditional transabdominal and new translumbar, consistently identified both kidneys in the 15-17th intercostal spaces and paralumbar fossa.
- Using the translumbar method, the maximum dimensions were recorded for the left kidney in the 16th intercostal space and the right kidney in the 15th intercostal space.
- The analysis revealed no significant difference (P > 0.05) between renal dimensions measured by traditional transabdominal and the new translumbar methods.
- However, significant correlations were found between overall renal dimensions measured by both ultrasound techniques and post-mortem measurements, with a better result for the translumbar method (mean r(2) = 0.92 cf. 0.88).
- The study identified good-to-excellent reliability for all translumbar measurements except for renal cortex.
- The reproducibility of results was better for the larger structures (overall length, width, and depth) than the smaller ones (cortex, medulla, and pyramids).
Conclusion
- The study concluded that the new translumbar ultrasound technique is a valid method for measuring renal dimensions in horses, offering a potential advantage for future diagnostic and disease-monitoring procedures.
