Does delayed operation for pediatric ureteropelvic junction obstruction cause histopathological changes?
Early correction in infants with ureteropelvic junction obstruction may not be necessary when initial differential renal function is greater than 40%. However, any decrease in differential renal function or recurrent urinary tract infections despite antibiotic prophylaxis warrant surgical correction of obstruction.
Posttransplant measures of early liver function and risk of failure, up to 1-year posttransplant, did not differ significantly based on peak or terminal donor serum sodium levels. These results suggest that donor serum sodium level likely has little clinical impact on posttransplant liver function.
