RESUMO
BACKGROUND: In the normal physiology of the bladder wall, it has sufficient elasticity so that it can maintain normal pressure during filling phase of bladder. Bladder functional pathology can cause many problems for patients. METHOD: This evaluation is a cross-sectional study conducted on patients suspected of neurogenic bladder. In this study, patient refered for urodynamic testing at first, urodynamic test performed by urologist and then Shear wave elastography was performed by radiologist. Data such as age, sex, height, and weight, and other demographic data were also evaluated. Patients were informed before and after the urodynamic and Shear wave sonography tests. Finally, the data were entered into SPSS software and were statistically analyzed. RESULTS: We observed that the mean and standard deviation of the age was 15.7 ± 6.2 years. Also found that in gender 19 (63.3%) patients were males and 11 (36.7%) were female. On the other hand, in terms of BMI, most patients were normal in this regard (50%), as well as in other cases, including weight loss in 3 (10%) patients, overweight in 8 (26.6%) patients, and obese were in 4 patients (13.3%). in our assessment about the efficacy of the ultrasound elastography approach to the anterior wall, which showed that the specificity of the test in the diagnosis of neurogenic bladder was 83% and this is statistically significant in patients (P < 0.05). We also observed in the posterior wall posture that the specificity of this test was 85% in the diagnosis of neurogenic bladder, which indicates a high diagnostic capability of this test, and this is statistically significant in patients (P < 0.05). CONCLUSION: Based on the results observed in this evaluation, ultrasound elastography has a high specificity for neurogenic bladder detection in comparison with urodynamic study. Accordingly, due to the less invasive nature of this method than urodynamic study, this method can be used to identify patients with neurogenic bladder.
