Objective: To determine the pattern of urinary tract changes in cases of ureterolithiasis as detected on helical computed tomography.
Material and Methods: Thirty patients with proven ureterolithiasis on IVU were included.
Among our study group the frequency expressed as percentages of various secondary signs of ureterolithiasis were hydroureter 25 (83.
02 mg/dL) secondary to left proximal ureterolithiasis (0.
0 mg/dL) right, secondary to right proximal ureterolithiasis (1.

CT has a high sensitivity and specificity for the diagnosis of nephrolithiasis and ureterolithiasis
Background Previous studies suggest that hematuria is 86% to 100% sensitive for detecting ureterolithiasis in patients with acute flank pain.
Further, the study was not blinded, no tests for statistical significance were performed, and the authors did not describe specific helical CT diagnostic criteria for ureterolithiasis.
Outcomes measured The primary results were the sensitivity, specificity, positive predictive value, and negative predictive value of hematuria, using a helical CT diagnosis of ureterolithiasis as the reference standard.
