Official title
Evaluating Shear Wave Elastography as a Predictor of Extracorporeal Shock Wave Lithotripsy Outcomes and Stone Composition in Children "A Prospective Study"
Overview
This prospective study aims to evaluate the role of shear wave elastography (SWE) as a non-invasive and radiation-free tool for predicting the success of extracorporeal shock wave lithotripsy (ESWL) in pediatric patients with renal stones. Currently, computed tomography (CT)-derived Hounsfield units (HU) are used to estimate stone hardness; however, repeated radiation exposure is a concern in children. SWE may provide an alternative method by assessing stone stiffness using ultrasound. Pediatric patients under 18 years with renal stones (6-20 mm) scheduled for ESWL will be included. SWE measurements will be performed prior to treatment, and patients will be followed for 3 months to assess treatment outcomes. The primary outcome is ESWL success, while secondary outcomes include correlation between SWE and HU, number of ESWL sessions required, prediction of stone composition, and assessment of the relationship between SWE measurements and stone composition. This study seeks to determine whether SWE can serve as a reliable predictor of ESWL outcomes, correlate with stone composition, and reduce the need for radiation-based imaging in children.
Primary outcome measures
- ESWL Success Rate [Time frame: 3 months with maximum 3 sessions ESWL]
Secondary outcome measures (1)
- Secondary Outcomes Related to SWE and ESWL [Time frame: Up to 3 months after ESWL]
