Abstract

Purpose

The aim of this study was to evaluate the testicular parenchyma in pediatric patients with testicular microlithiasis by shear wave elastography (SWE) and compare the values with normal control subjects.

Methods

Twenty-three patients previously diagnosed with testicular microlithiasis under follow-up for 20 ± 11 months were included in the study group. In the control group, 31 patients with no medical history that could affect testicular tissue were prospectively included. Forty-six testes in the study group and 62 testes in the control group were evaluated with gray-scale ultrasound and SWE.

Results

There were no differences in age and testes volume between the study and control groups. The mean SWE values of all testes based on elasticity and speed parameters in the study group were 8.84 ± 2.86 kPa and 1.66 ± 0.26 m/s, respectively. In the control group, mean SWE values were 5.26 ± 1.17 kPa and 1.31 ± 0.14 m/s, respectively. Elasticity values were significantly higher in testes with microlithiasis as compared with the control group (p < 0.001).

Conclusions

SWE evaluation demonstrates the effects of ultrastructural changes in elasticity that are not detected on gray-scale ultrasound. SWE is a more reliable method in follow-up examinations for pediatric testicular microlithiasis.
