Partial nephrectomy is a surgical procedure that removes only the tumour or diseased portion of the kidney along with a small margin of healthy tissue, rather than removing the entire organ. This kidney-sparing surgery is suitable for most small kidney tumours (typically less than 7cm) while preserving as much healthy kidney tissue as possible. The procedure completely removes the cancerous or abnormal tissue while maintaining kidney function for the patient’s long-term health.
During partial nephrectomy, the surgeon carefully excises the tumour and a thin rim of normal tissue surrounding it, ensuring complete removal while minimising damage to the remaining kidney. This approach differs from radical nephrectomy, where the entire kidney is removed. The preserved kidney tissue continues to filter waste from the blood, helping patients maintain kidney function and reducing the risk of chronic kidney disease.
