A new method for ultrasonographic measurement of kidney size in healthy dogs.

ABSTRACT: INTRODUCTION: The authors propose a simple method for assessment of canine kidney size derived from the radiological technique described by Finco et al in 1971. MATERIALS AND METHODS: In 26 healthy dogs ultrasonography was used to measure the length, height, and thickness of each kidney. These measurements were correlated with the lengths of the fifth and sixth lumbar vertebrae (L5 and L6), also measured by ultrasound. The resulting values were compared with the linear correlation method and the ratios defined using descriptive statistics. RESULTS: No significant differences were observed between the dimensions of the right and left kidneys. The length of both kidneys displayed significant correlation with both the length of L5 and that of L6. In both cases, the renal:vertebral length ratios ranged from 1.3 to 2.7. DISCUSSION: The ratio of kidney length to the length of L5 or L6 can be considered a useful parameter for assessing the size of the kidneys in healthy dogs. The normal range we identified in this study (from 1.3 to 2.7) is sufficiently narrow to allow sonographic detection of even limited changes in renal length.

Project description:The Clinical Measurement Ontology (CMO), Measurement Method Ontology (MMO), and Experimental Condition Ontology (XCO) were originally developed at the Rat Genome Database (RGD) to standardize quantitative rat phenotype data in order to integrate results from multiple studies into the PhenoMiner database and data mining tool. These ontologies provide the framework for presenting what was measured, how it was measured, and under what conditions it was measured.There has been a continuing expansion of subdomains in each ontology with a parallel 2-3 fold increase in the total number of terms, substantially increasing the size and improving the scope of the ontologies. The proportion of terms with textual definitions has increased from ~60% to over 80% with greater synchronization of format and content throughout the three ontologies. Representation of definition source Uniform Resource Identifiers (URI) has been standardized, including the removal of all non-URI characters, and systematic versioning of all ontology files has been implemented. The continued expansion and success of these ontologies has facilitated the integration of more than 60,000 records into the RGD PhenoMiner database. In addition, new applications of these ontologies, such as annotation of Quantitative Trait Loci (QTL), have been added at the sites actively using them, including RGD and the Animal QTL Database.The improvements to these three ontologies have been substantial, and development is ongoing. New terms and expansions to the ontologies continue to be added as a result of active curation efforts at RGD and the Animal QTL database. Use of these vocabularies to standardize data representation for quantitative phenotypes and quantitative trait loci across databases for multiple species has demonstrated their utility for integrating diverse data types from multiple sources. These ontologies are freely available for download and use from the NCBO BioPortal website at http://bioportal.bioontology.org/ontologies/1583 (CMO), http://bioportal.bioontology.org/ontologies/1584 (MMO), and http://bioportal.bioontology.org/ontologies/1585 (XCO), or from the RGD ftp site at ftp://rgd.mcw.edu/pub/ontology/.
