“…It is interesting to note that Pryles and Eliot's series was carried out in their renal clinic, and may, therefore, have included a higher proportion of bacteriuria without pyuria. Clarke (1960) and Turck, Browder, Lindemeyer, Brown, Anderson, and Petersdorf (1962) suggested that bacteriuria without pyuria is not uncommon in chronic and recurrent urinary infection, and our experience has substantiated this. However, in the present series no attempt was made to correlate pyuria and bacteriuria in children with known renal tract pathology.…”
