Shear Wave Elastografi til Forudsigelse af Ekstrakorporal Shock Wave Lithotripsis Resultater ved Nyresten hos Børn (SWE-ESWL)
Evaluering af Shear Wave Elastografi som en Prædiktor for Ekstrakorporal Shock Wave Lithotripsi-Resultater og Stensammensætning hos Børn "En Prospektiv Studie"
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.

Studiebefolkning
Pediatric patients under 18 years of age diagnosed with renal stones measuring 6-20 mm and scheduled for extracorporeal shock wave lithotripsy (ESWL). Patients will be recruited from the outpatient clinic and followed for 3 months.
Proper history, examination and basic laboratory investigations (CBC, coagulation profile, kidney and Liver functions, urine analysis and urine culture and sensitivity) will be performed for all participants.
Low dose CTUT will be performed as usual for all patient to record stone location, size (maximum longitudinal and transverse dimensions), and HU.
Renal stone elastography values will be measured by a single radiologist using grayscale renal US and SWE.
SWE measurements will be performed once prior to ESWL. A Philips EPİQ7 system (Philips Medical Systems, Bothell, WA) with a 1-5-MHz abdominal probe will be used for the procedure.

Pediatric Patients Undergoing ESWL
Pediatric patients (<18 years) with renal stones (6-20 mm) undergoing extracorporeal shock wave lithotripsy (ESWL). All patients will undergo baseline shear wave elastography (SWE) assessment prior to treatment. Patients will be followed for 3 months to evaluate ESWL success and its correlation with SWE measurements, Hounsfield units (HU), and stone composition. |
