nephron-sparing surgery
Surgical approach that preserves maximum kidney function by removing only diseased tissue rather than the entire kidney. Particularly important in pediatric cases with bilateral disease or genetic predisposition.
Full Definition
Nephron-sparing surgery encompasses surgical techniques designed to remove tumors or diseased kidney tissue while preserving as much normal kidney parenchyma as possible. In pediatric nephrology and urology, this approach is crucial for children with Wilms tumor, especially those with bilateral disease, genetic syndromes predisposing to multiple tumors, or pre-existing kidney dysfunction. The goal is to maintain long-term kidney function while achieving complete tumor removal, often requiring specialized techniques and close collaboration between pediatric urologists and oncologists.
Usage
Usage note: Emphasize preservation of function rather than just tissue; relevant in oncological contexts.
