Clinical Significance of Intraluminal Bladder Echoes on Sonography and Its Correlation with Urinary Tract Infection

Abstract

Background: Clinical significance of intraluminal bladder echoes on sonography and its correlation with urinary tract infection. Ultrasonography can provide information relative to the capacity of the bladder, change in bladder outline, changes in the thickness and structure of the wall, identification of luminal structures and mural masses, and identification of extrinsic lesions which may displace the bladder or distort the wall. Our primary objectives are: To determine the clinical significance of intraluminal bladder echoes; and To determine the association between intraluminal bladder echoes and UTI. Methods: The present study was conducted on patients who were referred to the Radiology department at ACME, Pariyaram during the period of October 1 2014 to March 31 2016. These patients were referred for abdominal or KUB ultrasound and also had their urinalysis done. Results: 560 subjects (males and females) who were found to have urinary bladder internal echoes were included in the study. Pretest probability: 48.2%. Pretest odds: 0.92. Posttest odds: 1.28. Posttest probability: 0.56 or 56%. Posttest odds: 0.278. Posttest probability: 0.21 or 21%. Conclusions: In this study, this particular sonological finding showed a low specificity as well as intermediate sensitivity for making the diagnosis of UTIs.
