Purpose:
To demonstrate the difference in tissue stiffness by comparing the value of the shear wave velocity (SWV) of postoperative undescended testicles with that of normal testes.
Methods:
This study included 39 patients and 30 healthy controls. US and p-SWE (VTQ) were performed using with a linear probe (4-9MHz). Forty-seven operated undescended testicles comprised "Group A", 27 testes with normal scrotal placement since birth in patient population comprised "Group B". A total of 60 testes in 30 healthy controls were included as "Group C". Finally, the testes of Group A, B, C were statistically compared in terms of the SWV and volume.
Results:
The shear wave values of the 47 testes in Group A were 0.75-2.8 (median, 1.1)m/s, and the SWVs of the 27 testes in Group B were 0.62-1.2 (median, 0.84)m/s. The SWVs of the 60 testes in Group C were 0.65-1 (median, 0.82)m/s. The testicular volumes of Group A ranged from 0.19 to 4.7 (median, 0.15)cm(3), Group B ranged from 0.34 to 8 (median, 0.74)cm(3) and Group C ranged as 0.4-15.5 (median, 0.91)cm(3).
Conclusions:
VTQ method of p-SWE is a new method that may reveal the difference in stiffness between scrotally placed testes and postoperative undescended testicles.
