Objective: To determine the accuracy of supine and prone approaches to sonographically measured kidney dimensions. Methods: The kidney dimensions of 109 participants were sonographically determined in supine and prone patient positions. The two measurements were compared with each other using the intra-class correlation, coefficient of variation for duplicate measurements and Bland-Altman plot. The two sets of measurements were each compared with measurements from computed tomography. Results: There was a very strong agreement between kidney dimensions in supine and prone positions. There was also an agreement between kidney dimensions in supine and prone positions and computed tomography measurements. Conclusion: The kidney dimensions obtained using patient-in-supine position and patient-in-prone position approaches may be equivalent and the two approaches may be used interchangeably.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
