Ureteral Dilatation with No Apparent Cause on Intravenous Urography: Normal or Abnormal? A Pilot Study

Table 1

Urine analysis ().

Investigation	Abnormal	Normal
Microscopic urine examination
Pus cells	8	10
RBCs	3	15
Urine culture	3 (E. coli > 100000 CFU/mL)	15
Microscopic examination for acid-fast bacilli (AFB)	3	15
Culture for Mycobacterium tuberculosis	3	15

1 case showed microscopic field full of pus cells; 7 cases showed 4–10 pus cells/HPF.
Urinary tract infection was found in 8 patients with a dilated ureter, out of which 3 showed growth of E. coli on urine culture, while in 2 cases Mycobacterium tuberculosis was isolated on culture (1 patient with genitourinary tuberculosis had no pus cells in urine).
