Prognostic features in @entity1 with @entity3551 due to XXXX .

@entity1 @entity3551 @entity644 @entity101 @entity177 @entity1011 @entity340 @entity293 @entity454
The histories of 22 @entity1 presenting during the first year of life with @entity3551 due to @entity340 were analyzed to determine outcome and prognostic features. Mean @entity1 age at the time of the initial surgical intervention was 39 days, and the mean duration of followup inclusive of renal function data was 5.8 years. One @entity1 died (5 per cent) and one had @entity454 . The mean preoperative and postoperative serum @entity1011 concentrations during the initial hospitalization were 3.1 and 1.4 mg. per dl., respectively. Neither value was significantly predictive of the @entity1011 concentration at final followup. In contrast, the nadir @entity1011 value during the first year of life correlated significantly with final renal function. @entity1 with nadir @entity1011 values less than or equal to 0.8 mg. per dl. by 12 months of age maintained @entity1011 levels less than or equal to 1.1 mg. per dl. at the time of final evaluation, whereas @entity1 with higher values during the first year of life were likely to have progressive @entity177 . Of 19 final @entity1011 determinations 6 were normal and 5 exceeded 1.5 mg. per dl. @entity644 , @entity101 , renal biopsy findings, @entity293 , unilateral nephrectomy and type of surgery did not correlate significantly with functional outcome. Followup studies of longer duration are needed to determine the ultimate outcome of these @entity1 , more than half of whom had some degree of @entity177 at final evaluation.
