To evaluate the diagnostic value of shear wave elastography (SWE) in the evaluation of undescended and retractile testes (RT) in a pediatric population.
We prospectively evaluated a total of 37 undescended testes (UDT), 15 RT, and 56 normal testes using SWE. The stiffness values were recorded for speed (m/s) and elasticity (kPa), and the mean stiffness values of groups were compared with each other.
The mean stiffness values of the UDT (13.80 ± 4.14 kPa, 2.14 ± 0.29 m/s) were higher than the mean SWE values of the normal testes (7.44 ± 2.11 kPa, 1.57 ± 0.21 m/s) (p < 0.0001). The mean stiffness values of the RT (9.64 ± 3.71 kPa, 1.75 ± 0.35 m/s) exceeded those of the normal testes (p = 0.004 for elasticity and p = 0.02 for speed). The mean stiffness value of the UDT was higher than the retractile ones (p < 0.0001 for elasticity and speed).
The higher stiffness values of the UDT and the RT compared to normal testes are likely reflective of underlying pathological alterations; hence, we suggest that SWE might serve as a valuable adjunct for the management of UDT and RT by assessing and monitoring ultrastructural changes.
评估剪切波弹性成像（SWE）在评估儿科人群中隐睾和回缩性睾丸（RT）方面的诊断价值。
我们前瞻性地使用SWE评估了总共37个隐睾（UDT）、15个RT和56个正常睾丸。记录速度（m/s）和弹性（kPa）的硬度值，并比较各组的平均硬度值。
UDT的平均硬度值（13.80±4.14 kPa，2.14±0.29 m/s）高于正常睾丸的平均SWE值（7.44±2.11 kPa，1.57±0.21 m/s）（p<0.0001）。RT的平均硬度值（9.64±3.71 kPa，1.75±0.35 m/s）超过了正常睾丸（弹性p = 0.004，速度p = 0.02）。UDT的平均硬度值高于回缩性睾丸（弹性和速度p<0.0001）。
与正常睾丸相比，UDT和RT的较高硬度值可能反映了潜在的病理改变；因此，我们建议SWE通过评估和监测超微结构变化，可能作为UDT和RT管理的有价值辅助手段。
