title: Evaluation of postoperative undescended testicles using point shear wave elastography in children.
abstract: 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.
  
  
  
  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.
  
  
  
  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).
  
  
  
  VTQ method of p-SWE is a new method that may reveal the difference in stiffness between scrotally placed testes and postoperative undescended testicles.
