To find clinical significance of routine "dipstick" urinalysis on admission, we analyzed the results of the "dipstick" urinalyses performed in 844 patients admitted to the pediatric department of Yeungnam University hospital from May 1, 1983 to October 31, 1984. Ketonuria, proteinuria, hematuria and glucosuria were found in 9.5%, 4.9%, 2.4% and 1.1% of the patients respectively. There were no significant differences by sex, age and presence of fever. However, proteinuria and ketonuria were found more frequently in the patients with dehydration (p<0.05). The degree of ketonuria showed a positive association w:th the severity of dehydration (p<0.005). All of the patients with proteinuria and ketonuria showed negative results on follow up. However, among 13 patients with hematura, 9 patients showed negative results and 4 patients had persistent hematuria on follow up. These 4 patients were found to have chronic pyelonephritis (2), asymptomatic urinary tract infection (1) and benign recurrent hematuria (1). This routine "dipstick" urinalysis on admission seems to be simple test which is useful in detecting unrecognized kidney and other urinary tract disease.
