ANALYSING DATA ON THE ETIOLOGY, CLASSIFICATION AND PROGRESSION FACTORS OF CHRONIC KIDNEY DISEASE IN CHILDHOOD

Chronic kidney disease is defined as kidney damage or decline in kidney function for three months or more regardless of nosological diagnosis. The concept of chronic kidney disease and the classification of CKD stages has been used in modern nephrology since 2002 by the NKF-K/DOQI initiative. In 2003, the term was proposed for use in paediatric nephrology. Kidney disease in childhood continues to progress into adolescence and adulthood, leading to their chronic disease and terminal stage.
