Partial nephrectomy, ablation & active surveillance of small renal masses
Most small kidney tumours found on scans grow slowly. Options range from watching them, to freezing or heating them, to removing just the tumour and keeping the kidney.
Small renal masses (<4 cm) are increasingly found incidentally; 20-30% are benign or indolent. Active surveillance (DISSRM, Canadian registry) shows low metastatic risk with growth-triggered intervention. Partial (nephron-sparing) nephrectomy, usually robotic, is preferred for T1 tumours; radical nephrectomy for larger or central tumours. Percutaneous cryoablation or microwave ablation for small tumours in comorbid patients; renal mass biopsy and SBRT (FASTRACK II) are expanding roles.
How it works
Nephron preservation reduces chronic kidney disease and cardiovascular mortality; surveillance exploits the slow natural history of most small masses.
- Kidney function preserved
- Avoids overtreatment of benign masses
- No reliable imaging biomarker for aggressive small tumours
- Surveillance anxiety and adherence
