“…There is limited information regarding the use of SWE in the evaluation of testicular lesions. Investigation of the role of SWE in the overall assessment of background parenchyma has suggested that values may be elevated in the case of testicular microlithiasis [386], infertility [387], undescended testis [388]. It also has the potential to differentiate seminomas from non-seminomatous lesions [389] and has been evaluated in burnt-out tumors [390].…”

“…However, volumetric changes in testes with varicocele might manifest at a later stage of the disease, and testicular volume might not be an ideal surrogate marker of underlying ultrastructural changes in the testes. The feasibility and efficiency of SWE in detecting ultrastructural changes in testicular parenchyma in various diseases have been demonstrated in previous reports [5][6][7]. Furthermore, several studies have focused on the impact of varicocele on the testes using elastography.…”

Purpose: This study was conducted to evaluate the potential role of shear wave elastography (SWE) in the evaluation of testes in patients with varicocele. Methods: A total of 116 testes of 58 patients with left-sided varicocele and 58 testes of 29 agematched healthy controls were included in the study. The patients' testes were classified into groups A (normospermic) and B (oligospermic) based on the presence of oligospermia. The mean SWE values and volume of the testes with varicocele were compared with the contralateral normal testes of the patients and the testes of healthy controls. Results: The mean SWE value of the left testes in groups A (4.77±1.16 kPa) and B (6.15±1.96 kPa) exceeded that of the healthy controls (3.79±0.94 kPa) (P<0.001). The mean SWE value of the left testes in group B (6.15±1.96 kPa) exceeded that of group A (4.77±1.16 kPa) (P=0.002). No correlation was observed between testicular stiffness and the grade of varicocele (r=0.102, P=0.423). Conclusion: The testes with varicocele were stiffer than the contralateral testes and the testes of healthy controls, and SWE might play an auxiliary role to conventional ultrasonography in assessing pathologic alterations in the testis owing to varicocele.

“…A recent study using SWE showed that the mean testicular stiffness was significantly higher in uUDT than in CGN, without significant volume difference, in children with an age range of 1-18 years [15]. Another study used point SWE for postoperative UDTs, and demonstrated the different stiffness in postoperative UDTs compared to CGN and normal testes [14]. However, they did not evaluate the growth pattern of UDTs.…”

“…In addition, US elastography is a simple noninvasive method for measuring tissue elasticity [10]. Although a few studies have tried to use this technique in UDTs [11][12][13][14][15], to our knowledge there has not been a study that compared the elasticity differences between normal testes and UDTs in young children preoperatively using shear wave elastography (SWE).…”

Aims: To evaluate the differences and changes of testicular volume and elasticity in normal (NL) testes and undescended testes (UDTs) of children using shear wave elastography (SWE).Materials and methods: Testicular ultrasound images from children younger than 60 months old were retrospectively reviewed. Testicular volumes and elasticities were compared between the UDT group and NL group. In patients with unilateral UDT (uUDT), we also compared the values between uUDT and contralateral grossly normal (CGN) testis groups.Results: There were 25 UDTs including 4 bilateral in the UDT groupand 54 normal testes in the NL group. While testicular volume was significantly smaller in UDT (vs. NL) and uUDT (vs. CGN) groups, the elasticity was not different. Testicular volume was positively correlated with age in both NL (r=0.474) and CGN (r=0.729) groups (p<0.001), while there was no correlation in the UDT group. Testicular stiffness showed negative correlation with age in the NL group (r=-0.390, p=0.004) and positive correlation in the UDT group (r=0.426, p=0.034).Conclusions: Instead of increasing volume and decreasing stiffness of normal testes during development of the early 60 months, UDTsexhibited smaller volume and increasing stiffness. The CGN testes of uUDT patients showed increasing volume without stiffness change.
