Comparative Study[Comparison between the 3- and the 24-hour urine collection for creatinine clearance].
Endogenous creatinine clearance was studied in thirty children with various renal diseases and variable degrees of functional deterioration. Two different procedures or urine collection were used on each child: 1) twenty-four-hour urine collection with one blood sample and immediately afterwards 2) three one-hour consecutive periods of urine collection, with one previous blood sample (the one used for the 24-hour procedure). ⋯ The results obtained with both procedures did not show significant difference. The three-hour periods procedure may be recommended for hospitalized patients, specially infants or young children, and also when the parents are not reliable enough for hydrating the patients and for performing a complete collection of urine in a 24 hour period.
