Abstract: Acute renal failure (ARF) is a major public health problem, with incidence in newborns and children ranging from 4.5 to 82%, and mortality from 19 to 83%. The aim was to determine the frequency of acute renal failure in children admitted to the pediatric ward of the Hospital National Ignace Deen. Patients and Method: This was a dynamic descriptive study covering the period from April 1er to September 30 2023; children under 16 years of age with a sudden rise in creatinine above 1.6 mg/dl were included in the study. Results: The incidence of acute renal failure was 7.93%; mean age 8.04 ±3 years. The sex ratio was 2 in favor of men. Clinical signs were dominated by fever, physical asthenia, anorexia and conjunctival pallor (91.67%, 66.67%, 58.33% and 56.25% respectively); proteinuria, hematuria and biluribinuria were found at Urine Test Strip (BU) (54.17%, 29.17% and 41.67% respectively). Stage I ARF predominated, at 52.02%; organic ARF was found in 54.10% of cases. Mortality in this series was 14.58%. Conclusion: the management of pediatric renal failure at the complication stage is currently a major problem for healthcare professionals, due to the lack of nephropediatric services or specialized centers for extra-renal purification in the various health facilities in Guinea.Abstract: Acute renal failure (ARF) is a major public health problem, with incidence in newborns and children ranging from 4.5 to 82%, and mortality from 19 to 83%.
