Accuracy for Diagnosis of Patients Presented with Painless Hematuria by MDCT Urography
Keywords:
MDCT urography; painless hematuriaAbstract
Background: Computed tomography urography (CTU) is a relatively new diagnostic imaging examination providing comprehensive evaluation of the upper and lower urinary tract. CTU is justified as a first-line test for patients with macroscopic hematuria, at high-risk for urothelial cancer.
Objective: To assess the role of multi-detector row CT (MDCT) urography, using a MDCT for evaluation of patients presenting with painless hematuria, in Siriraj Hospital, Bangkok, Thailand.
Methods: Between 2006 and 2008, 16 consecutive MDCT urography examinations were retrospectively reviewed by two radiologists. Sensitivity, specificity, PPV, NPV and accuracy of MDCT urography compared with surgical, histopathological findings and other imaging modalities were calculated.
Results: In 11 out of 16 patients, the causes of painless hematuria were identified on MDCT urography. The most common cause was benign urothelial lesions in 5 cases. About uroepithelial malignancies, a detectable smallest lesion was about 0.8 cm in diameter.
Conclusion: Sixty-four row MDCT urography provided satisfactory results in detection of urinary tract lesions with high accuracy in painless hematuria patients.
