A Descriptive Analysis of Computed Tomography Urography (CTU) Cases in Patients With Hematuria in Comparison with Ultrasound Kub(US) And Cystoureteroscopy (CU)

Abstract

The aim of our study was to correlate and evaluate the accuracy of Computed Tomography Urography (CTU) results with other imaging modalities in patients who presented with haematuria in 2020. Retrospectively comparison of CTU findings with ultrasound KUB(US) and cytoureteroscopy (CU) also have been made.  This is a retrospective study in which all CTU cases in a total of 186 patients with hematuria in 2020 were included in this study. The data was retrieved from the PACS system at Department of Radiology in Hospital Sultanah Nur Zahirah Kuala Terengganu. Frequency of the clinical manifestation were calculated among the patients and compared between US, CU and CTU findings. A total of 186 patients with hematuria involved in this study. Demographic data on clinical information have exhibited microscopic hematuria, calculi, hydronephrosis and renal calculi yielded higher percentage with 81.7%, 82.8%, 72.0% and 63.4%, respectively. The correlation between hematuria and US together with CTU findings was not significant with p value of 0.259. The data also revealed 133 patients (71.5%) had similar US and CTU findings. Meanwhile, 76.0% patients who underwent CU also yielded consistent findings with CTU. This study demonstrated no significant correlation between CTU - US findings in the detection of causes of hematuria. However, there was a good correlation of US and CU with CTU in a detection causes of hematuria with almost equal accuracy and sensitivity.
