Morbidity and mortality study

Chronic kidney disease (CKD) is described as a state of progressive loss of renal function or renal damage that develops over a period of months and years, while its terminal stage or stage 5 is an irreversible deterioration that is incompatible with life if replacement therapy is not instituted, either by dialysis or renal transplantation.There is international consensus in considering CKD as structural or functional deterioration of the kidney, manifested by markers of renal damage detected directly from histological alterations in the renal biopsy, or indirectly by the presence of albuminuria, alterations in the urinary sediment or through imaging techniques; or by an estimated glomerular filtration rate (eGFR) less than 60 ml/min/1.73m2 for a period greater than 3 months, independently of the cause that provoked it and with implications for health. The disease is stratified into five stages.
