RENAL TUBULAR DISEASES

Renal tubular diseases represent a diverse group of disorders affecting the structure and function of the renal tubules, leading to disturbances in water, electrolyte, and acid-base balance. These conditions may be inherited or acquired and can significantly impair kidney function if not diagnosed and treated promptly. Renal tubular disorders are associated with abnormalities in the reabsorption and secretion processes of the nephron, resulting in various clinical manifestations such as electrolyte imbalances, metabolic acidosis, polyuria, and growth retardation in children. This article reviews the etiology, pathophysiology, clinical features, diagnostic approaches, and current management strategies of renal tubular diseases. Early recognition and appropriate treatment are essential to prevent complications and preserve renal function.
