Crystallographic investigation of urine in newborn with renal disturbance due to asphyxia.

Objective: The aim is to increase the efficiency of diagnosis of renal injury in neonates with asphyxia by identifying of structural markers according to research facies of urine in newborns of different gestational ages.

Patients And Methods: Materials and methods: The study involved 150 full-term with signs of kidney damage due to asphyxia: 75 babies with severe asphyxia, and 75 children with moderate asphyxia and 100 preterm infants: 50 children with severe asphyxia and 50 children with moderate. Comparison groups: group 1 consisted of 20 full-term infants, group 2 which included 20 preterm neonates. Material for the study - morning portion of urine, which was collected at 8-10 a.m. on 1-2 and 7-8 days of life.

Results: Results: morphological picture of facies of newborns with asphyxia depends on the severity of pathological changes in the urine (proteinuria) and urine output. Structure of facies in babies with renal distorbance due to severe asphyxia indicates a significant loss of organic and mineral substances in the urine. The width of the peripheral zone facies, the amount of solid particles transferred depends on the severity of asphyxia, the difference in morphology facies is maintained even at the end of the early neonatal period.

Conclusion: Conclusions: Analysis of dried drops of urine in infants with renal impairment on the background of asphyxia can be used as one of the criteria for assessing kidney function and have prognostic value.
