“…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.…”

“…SWE provides quantitative information regarding the stiffness of the relevant tissue by tracking shear waves passing through them [5]. The diagnostic value of elastography has been explored in undescended testes, testicular tumors, hydrocele, and testicular microlithiasis, with favorable results [5][6][7][8]. Several studies have investigated the role of SWE in assessing testicular parenchyma and the associations between SWE values and sperm parameters in the presence of varicocele.…”

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.

“…Another study investigated TML in 9 young patients and found that the mean testicular volume did not differ from the control group 17 . Bayramoglu et al investigated testicular volume in 23 pediatric patients with TML and 31 pediatric patients without TML, and found no difference in testicular volume between the study and control groups 18 . However, it is possible that ethnicity also affects testicular volume 19 .…”

Purpose Ultrasonography is a useful tool to measure testicular volume. According to the European Society of Urogenital Radiology, the combination of testicular atrophy and testicular microlithiasis (TML) is a risk factor for testicular cancer. Testicular atrophy is defined as a volume of less than 12 ml. The aim of this study was to compare testicular volume in patients with TML to patients with normal testicular tissue. Materials and Methods From 2013 to 2015 we included a total of 91 adult patients with TML, and 91 adult patients with normal testicular tissue as a control group. All patients underwent scrotal B-mode ultrasound investigation including measurement of width, length and height in both testicles. Testicular volume was calculated using the formula π/6×length×height×width. Results The median age for patients with TML was 48 years (range: 19-94 years), and 48 years (range: 20–75 years) in patients with normal tissue. No statistically significant difference was found between total testicular volume (both testes) >30 ml in patients with TML compared to patients without (OR 0.77 (95% CI 0.43-1.38, p=0.37). However, patients with TML tended to have lower testicular volume compared to patients without TML, when investigating testicular volume below 12 ml. Conclusion Overall, no association was found between testicular volume and TML, but there was a trend indicating that severe atrophy is often seen in patients with TML compared to patients without TML. However, a significant difference was only found in testicular volume ≤8 ml.

“…The diagnostic usefulness of testicular sonoelastography has been investigated in multiple studies on undescended testis, testicular microlithiasis, scrotal hydroceles, testicular torsion, and malignant tumors [5][6][7][8][9]. Several previous studies found that varicoceles change the testicular stiffness measured by elastography [10][11][12][13].…”

A preliminary study of shear-wave elastography for the evaluation of varicocele in adolescents and young adults

To compare the change of testicular stiffness during the Valsalva maneuver using shear-wave elastography (SWE) in adolescents and young adults with varicocele according to clinical severity and evaluate the role of SWE in the diagnosis of varicoceles.Methods: Patients undergoing testicular ultrasonography for diagnosis of varicocele or for follow-up after varicocelectomy from June 2016 to February 2017 were included in this study. 54 testicles of 27 consecutive patients (mean age, 15.9 years) were classified according to clinical grade (grade 0-3). Testicular mean stiffness (E mean) using SWE was measured at rest and during the Valsalva maneuver. The correlation between multiple ultrasonographic parameters (volume asymmetry, E mean at rest, and absolute and percentage changes of E mean during the Valsalva maneuver) and the clinical grade was assessed using a Spearman correlation test. Results:The E mean measured at rest was similar among the four clinical grades. During the Valsalva maneuver, increased testicular stiffness was more frequently observed in patients with grades 2 or 3 varicoceles, but rarely observed in those with grade 0 or 1 varicoceles. The changes in E mean were positively correlated with the clinical grade (all p-values < 0.001),whereas the E mean at rest and volume asymmetry were not (all p-values > 0.05). Conclusion:A transient and reversible increase of testicular stiffness during the Valsalva maneuver was observed in adolescents with high-grade varicocele, and the degree of stiffness change correlated with the clinical grade. SWE changes during the Valsalva maneuver could be used as a surrogate indicator of venous congestion.

Shear wave elastography evaluation in pediatric testicular microlithiasis: a comparative study

Abstract: SWE evaluation demonstrates the effects of ultrastructural changes in elasticity that are not detected on gray-scale ultrasound. SWE is a more reliable method in follow-up examinations for pediatric testicular microlithiasis.
