Role of Conventional IVU (Intra Venous Urography) and Computed Tomography in Patients of Urinary Tract Calculopathy
Journal Title: Journal of Medical Science And clinical Research - Year 2018, Vol 6, Issue 1
Abstract
Background: From calculus disease to hematuria, imaging has been of great importance in the diagnosis of many diseases of the urinary tract. Advances in imaging technology have changed the practice of uroradiology significantly. CT urography represents one of the most advanced developments in imaging the urinary tract to date. Excretory urography has been the initial modality for upper tract imaging in patients with hematuria, flank pain, and other urologic diseases for the past 5 decades. With the recent introduction of multi-detector row helical CT, the uroradiologic evaluation of patients with common and complex disease is changing rapidly. This study is an attempt to review the role of IVU or CT Urography, should supercede as investigation of choice in varied settings and evaluate the obstructed tract anatomy in patients with non-functioning kidneys and various urinary tract disorders. Materials And Method: It was a hospital based, comparative study, with a sample size of 60 patients, during the period of 2 years, in the department of Radio-Diagnosis, Krishna institute of Medical sciences, karad. Patients referred with acute flank pain, hematuria or ultrasonologically detected cases of urinary tract calculopathy were included in the study. Patients were randomly allocated in following two groups of 30 patients – IVU Group and CT Urography Group. Then according to the analysis of both the groups, the results were compiled and compared statistically and graphically to depict the individualistic role of each modality, their cons and pros in varied settings and management in patients with urinary tract calculopathy. Results: Amongst the two groups the number of patients whose urinary stones were detected was higher in the CT Urography group than IVU group. Urography group had a higher proportion of Renalstones, mid & lower ureteral stones, than the IVU group. The mean size of obstructing calculi detected by IVU was 6.03±1.08 mm as compared 6.80±2.01 mm as detected by CT Urography. The accuracy of detecting etiology by CT Urography was 100% as compared to 66.7% of IVU.CT was able to differentiate the acute and chronic changes in the renal parenchyma due to obstructive uropathy in many cases however IVU was unable to do so. Conclusion: CTU is better than IVU in detection of urinary stone, saves time and is cost effective however IVU involves less radiation dose. From this study we conclude that CT provides a better diagnostic information in the patients with urinary tract calculopathy
