“…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].…”

Objectives To compare elastography measurements in men with normal testicular tissue, testicular microlithiasis and testicular cancer. Methods A total of 248 consecutive patients were included. All men provided written informed consent. Testicular stiffness was assessed using shear wave elastography (SWE). Three SWE velocity measurements were assessed in each testicle. The patients were divided into three groups; men with normal testicular tissue (n=130), men with testicular microlithiasis (n=99) and men with testicular cancer (n=19). Results We found a higher mean velocity in the group of patients with testicular cancer (1.92 m/s (95% CI 1.82–2.03)) compared to both the group with normal tissue (0.76 m/s (95% CI: 0.75–0.78)) (p<0.001) and the group with testicular microlithiasis 0.79 m/s (95% CI: 0.77–0.81) (p<0.001). Conclusion The presence of testicular microlithiasis increased stiffness slightly, but within the range of variation in normal testicles. Increased stiffness may indicate testicular malignancy in testicular lesions. Ultrasound elastography could be a very useful tool when investigating scrotum.

“…Urologists and andrologists always use palpation to understand changes in testicular tissue, but this type of analysis is subjective (Rocher et al, ). While testicle atrophy can be determined by RDUS, tissue degeneration before atrophy cannot be determined (Fontaine et al, ).…”

Effects of varicocele on testicles: Value of strain elastography: A prospective controlled study

et al. 2018

The aim of this study was to evaluate the structural changes in testicles of the patients with varicocele by strain elastography (SE) and to identify the relationship between semen analysis and hormone levels considering SE results. The patients were separated into two groups as varicocele and control, according to their physical examination and the scrotal colour duplex ultrasonography results. All patients underwent examination by hormonal profile, semen analysis, colour duplex ultrasonography and sonoelastography. Testicular volume, resistive index (RI) of intratesticular arterial flow, strain rate and varicocele measurements were recorded. The left testicle strain ratios (SR) median value was 0.18 (0.15–0.26) in the varicocele group and 0.25 (0.19–0.28) in the control group (p < 0.001). The median RI value was 0.59 (0.52–0.64) in the varicocele group and 0.52 (0.5–0.59) in the control group (p < 0.001). No difference was found considering volume between the right and left testicles in either group. These results showed that elastography could be useful to detect the damage caused by varicocele on testicles in early period. However, studies with more patients would help to increase elastography's value and reliability.
