Abstract

The aim of this study was to demonstrate the utility of Shear Wave Elastography (SWE) in predicting the success of extracorporeal shock wave lithotripsy (ESWL) in pediatric patients. A total of 102 patients < 18 years of age with a diagnosis of kidney stones underwent ESWL between May 2021 and December 2023. SWE measurements of the stones were performed in all patients prior to ESWL. The subjects were divided into two groups: those who responded to ESWL and those who did not. Age, gender, stone location, stone size, body mass index (BMI), Hounsfield Unit (HU), and stone SWE values were compared between the groups. Among the 102 patients included in the study, 78 exhibited a positive response to ESWL. In the responder group, the SWE, HU, and stone size values were significantly lower than the non-responder group (p < 0.05). SWE exhibited significant efficacy in discriminating between responders and non-responders [area under the curve (AUC): 0.979 & p = 0.000]. A SWE cutoff value of 13.70 kPa was identified for patient differentiation [AUC:0.929 & p = 0.000]. SWE appears to be an effective method for predicting the success of ESWL in pediatric patients and may serve as an alternative parameter to HU for pre-treatment evaluation.

期刊介绍： Official Journal of the International Urolithiasis Society The journal aims to publish original articles in the fields of clinical and experimental investigation only within the sphere of urolithiasis and its related areas of research. The journal covers all aspects of urolithiasis research including the diagnosis, epidemiology, pathogenesis, genetics, clinical biochemistry, open and non-invasive surgical intervention, nephrological investigation, chemistry and prophylaxis of the disorder. The Editor welcomes contributions on topics of interest to urologists, nephrologists, radiologists, clinical biochemists, epidemiologists, nutritionists, basic scientists and nurses working in that field. Contributions may be submitted as full-length articles or as rapid communications in the form of Letters to the Editor. Articles should be original and should contain important new findings from carefully conducted studies designed to produce statistically significant data. Please note that we no longer publish articles classified as Case Reports. Editorials and review articles may be published by invitation from the Editorial Board. All submissions are peer-reviewed. Through an electronic system for the submission and review of manuscripts, the Editor and Associate Editors aim to make publication accessible as quickly as possible to a large number of readers throughout the world.
