About this trial
Hydronephrosis is common during pregnancy and is often physiological; however, it may also result from true obstruction requiring intervention. Differentiating between physiological and obstructive hydronephrosis remains a clinical challenge using conventional ultrasound.
This prospective observational study aims to evaluate the diagnostic accuracy of renal cortical stiffness measured by shear wave elastography (SWE) in differentiating obstructive from physiological hydronephrosis in pregnant women. Participants presenting with hydronephrosis will undergo clinical assessment, laboratory investigations, and ultrasound evaluation including SWE measurements.
The diagnostic performance of SWE will be assessed using receiver operating characteristic (ROC) analysis, and optimal cut-off values will be determined. The study aims to provide a safe, non-invasive, and quantitative tool to improve diagnosis and guide management in pregnant patients with hydronephrosis.

Treatments tested in this trial
Shear Wave Elastography (SWE)
Diagnostic testShear wave elastography (SWE) is a non-invasive ultrasound-based imaging technique used to measure renal cortical stiffness. In this study, SWE is performed as a diagnostic assessment tool in pregnant women with hydronephrosis to evaluate its ability to differentiate between obstructive and physiological causes. No therapeutic intervention is applied.
Treatment groups
Trial outcomes
Primary outcomes
Diagnostic accuracy of shear wave elastography (SWE) in differentiating obstructive from physiological hydronephrosis
Diagnostic performance of renal cortical stiffness measured by SWE will be evaluated using receiver operating characteristic (ROC) analysis, including area under the curve (AUC), sensitivity, and specificity based on final diagnosis.
Secondary outcomes
Optimal SWE cut-off value for detecting obstructive hydronephrosis
Determination of the optimal renal cortical stiffness cut-off value using ROC analysis to differentiate obstructive from physiological hydronephrosis.
