RSG (renal scarring and growth)

RSG, or renal scarring and growth, refers to the long-term effects on the kidneys caused by infections or injury. When the kidneys get damaged—often from infections—they can develop scars that may reduce their ability to filter waste efficiently. This scarring can also impact how well the kidneys grow, especially in children, potentially affecting their overall kidney function later in life. Monitoring RSG is important to prevent further damage and preserve kidney health through appropriate care and management.
