Abstract Background: Patients with neurogenic bladders leading to increased storage pressure due to hypocompliance are at risk of upper urinary tract injury. Currently, urodynamics is considered the gold standard to evaluate bladder function. However,It is uncomfortable and invasive investigation that requires catheterization which increases risk of urinary tract infection. Objectives and aim of work: To determine the role of shear wave ultrasound elastography as a new method for evaluating urinary bladder dysfunction associated with elevated bladder pressure to be able to diagnose patients with neurogenic bladder. Methods: The study was carried out on 20 patients with neurogenic bladder and 20 healthy individuals as control group. After clinical evaluation and performing urodynamics in the urology department to measure compliance and Pdet in cmH2O, Ultrasound SWE was performed in the radiology department on the anterior bladder wall and mean SWS was calculated in m/s. The relationship between SWS and Pdet was estimated using Mann Whitney U test. Chi2 test was used to compare mean SWS between study groups. Results: Correlation matrix showed that Pdet and mean SWS of the anterior bladder wall were strongly correlated with r= 0.79 and p value <0.001. Mean SWS readings were significantly higher among cases compared to controls (2.6± 0.7 m/s vs. 1.3± 0.2) with p value <0.001 and cutoff point 1.67 m/sec. Conclusion: SWE is a promising non invasive highly sensitive modality in evaluation of NB. |
