Surveillance versus ablation for incidentally diagnosed small renal tumours: the SURAB feasibility RCT

There is uncertainty around the appropriate management of small renal tumours. Treatments include partial nephrectomy, ablation and active surveillance. To explore the feasibility of a randomised trial of ablation versus active surveillance.
