ABSTRACT
Purpose : Urine collection using a sterile adhesive bag for urinalysis has been used commonly in infants and young children. However, this method has had some drawbacks. So, this study was performed to evaluate the usage of disposable diapers as a substitute for the routine urine collection method.
Methods : 60 mL of self voided fresh urine was collected from 99 patients. Half of the urine was poured on the disposable diapers which did not contain absorbent gel beads. After 1 hr, we obtained the urine samples(extracted urine) by compressing the wet diapers using a 50 ml syringe. Routine, microscopic and biochemical analyses were performed on the other half of fresh urine and extracted urine. Then we compared each result by correlative analysis.
Results : 198 samples from 99 patients were evaluated. The results of routine urinalysis except WBC and biochemical urinalysis showed a significant correlation between the two groups(P<0.05). The relative coefficients of urine SG, pH, glucose, protein, blood and leukocytes between the two groups were 0.964, 0.938, 0.977, 0.956, 0.931 and 0.738, respectively. Those of urinary sodium, potassium, chloride and creatinine were 0.997, 0.998, 0.995 and 0.998, respectively Microscopic examinations showed lower relative coefficients than the other results, 0.740 for RBC and 0.602 for WBC, but these were still significant(P<0.05).
Conclusion : The results of the urine analysis with extracted urine from diapers correlates well with that of fresh urine. This new method is very helpful and can be used as an alternative of urine collection, especially for infants and young children. (J Korean Soc Pediatr Nephrol 2005;9:128-136)
