Utility of 2‐Dimensional

Objectives The aim of this study was to investigate the efficacy of 2-dimensional (2D) shear wave elastography (SWE) in the diagnosis of acute cystitis (AC) in children. Methods Between June 2019 and March 2020, 126 children with AC and 126 healthy participants were prospectively investigated by 2D SWE and B-mode ultrasound. Elastographic measurements were performed by drawing the contours of the posterior wall of the bladder between the ureter orifices using a free region of interest. The quantitative 2D SWE values of the patients and the healthy group were compared. Results The mean 2D SWE values of the bladder wall were significantly higher in patients with AC compared to the healthy group (P= .001). On B-mode ultrasound imaging, the bladder wall thickness of patients with AC was higher than that in the healthy group (P= .001). On 2D SWE, when the cutoff value used was 9.25 kPa, the sensitivity, specificity, positive predictive value, and negative predictive value were 92.1%, 88.1%, 89.3%, and 92.6%, respectively, whereas when the cutoff value used was 1.72 m/s, the sensitivity, specificity, positive predictive value, and negative predictive value were 90.5%, 88.9%, 89.1%, and 90.7%. There was a statistically significant positive correlation between the 2D SWE values and wall thickness measurements (P < .001). Conclusions Two-dimensional SWE is a noninvasive, fast, and effective imaging method to evaluate the bladder wall in children with AC

Assessment of testes with two-dimensional Shear Wave Elastography in patients with operated inguinal hernia

Aim: We compared the two-dimensional shear-wave elastography (2D-SWE) values between the testes with same side operated inguinal hernia (IH) and the contralateral testes, as well as the testes of healthy volunteers without IH. Material and methods: A total of 189 participants (117 unilateral [117 testes] and 8 bilateral operated IH patients [16 testes] and 64 healthy volunteers [128 testes]), providing a total of 378 testicles, were investigated prospectively. All patients underwent B-mode ultrasonography (US) and 2D-SWE examinations. Operation type, the period between diagnosis and operation, the period since the operation, testes volumes, and 2D-SWE values were compared. Results: The B-mode US finding of the testes were normal in all participants. The mean testes' volume of same side operated IH was significantly lower comparing to contralat-eral testes and the healthy group (p0.005). Conclusions: The 2D-SWE can be used as an effective imag-ing method to evaluate testicular stiffness with objective numerical values, to estimate the severity of histologic damage in patients with operated IH
