Abstract
Objective:
This study examined the clinical significance of microscopic hematuria and grade of hydronephrosis in ureteral calculi patients visiting the emergency department (ED).

Methods:
The EDs of two medical centers were reviewed retrospectively from August 1, 2012 to July 31, 2017. The total ureteral calculi patients were 2,069 and 1,593 patients were analyzed after exclusion. The normal range of microscopic hematuria in both medical centers was 0-5/high power field (HPF) of red blood cell in urinalysis. Therefore, microscopic hematuria more than 5/HPF was defined as positive. The size of the stone, grade of hydronephrosis (normal, mild, moderate, and severe) and location of ureteral calculi in the non-contrast abdomen and pelvis computed tomography (CT) was measured by one person at each medical center using same method. The patients with or without microscopic hematuria and grade of hydronephrosis were then compared.

Results:
The median size of the ureteral calculi patients without and with microscopic hematuria was 5.4 mm (range, 3.8-9.0 mm) and 4.0 mm (range, 3.0-5.8 mm) (P<0.001). The patients grouped as normal to mild, and moderate to severe hydronephrosis, without microscopic hematuria was 191 (16.5%) and 91 (20.9%), respectively. On the other hand, microscopic hematuria was 966 (83.5%) and 345 (79.1%) (P=0.042). According to the location of ureteral calculi, with and without microscopic hematuria was 81.9% and 18.1% in the upper ureter, 82.9% and 17.1% in the mid ureter, and 82.6% and 17.4% in the lower ureter, respectively (P=0.935).

Conclusion:
The median size of the stone and grade of hydronephrosis were related to microscopic hematuria but the location of the ureteral calculi was not related. Therefore, in cases without microscopic hematuria in suspected ureteral calculi, clinicians should check the abdomen and pelvis CT for an accurate diagnosis and treatment of ureteral calculi.
