Diagnostic accuracy of kidney shear wave elastography at the diagnosis of ureteral stones
Abstract
Aim: To determine the efficacy of kidney shear wave elastography (SWE) in patients
diagnosed with ureteral stones
Method: Both kidneys of 30 patients were evaluated prospectively with SWE. The
ureteral stone size and the degree of hydronephrosis were determined by sonographic
examination. The contralateral kidney was accepted as the control parameter. Stone
size, grade of hydronephrosis and kidney shear wave speed changes were noted and
their relations were examined for statistical significance.
Results: Affected kidney group had significantly increased SWE values than the
control group. (3.87+-1.22 vs 2.06+-0.72 m/sec) (p=0.01). Neither the stone size nor
the kidney SWE values showed a correlation with the gender. There was a positive
correlation between the grade of hydronephrosis and the stone size (p=0.047,
r=0,36). Kidneys with grade 2 hydronephrosis had significantly higher SWE values
than those with grade 1 hydronephrosis.
Conclusion: SWE is a promising tool to observe the parenchymal elasticity changes
in patients with hydronephrosis secondary to ureteral stones. Further studies are
necessary to confirm the research results
