OBJECTIVE To compare the intermediate‐term outcomes of patients with clinical T1a renal tumours who were treated nephron‐sparing surgery by partial nephrectomy (PN), preferred approach for small (cT1a) tumours, or radiofrequency ablation (RFA), recently offered to selected as an alternative, less morbid technique. PATIENTS AND METHODS We identified stage masses had ≥ 2 years follow‐up; those bilateral synchronous metachronous metastatic disease at presentation, a family history cell carcinoma excluded. From July 1996 January 2004 110 PNs in our database; 37 fulfilled inclusion criteria either open (30) laparoscopic PN (seven) and 40 percutaneous (26) (14) RFA. RESULTS The mean (range) follow‐up RFA groups was 30 (18–42) 47 (24–93) months, respectively; respective tumour size 2.41 2.43 cm. There one incomplete two local recurrences group, group (one contralateral kidney). no disease‐specific deaths. overall actuarial disease‐free probability groups, respectively, 95.8% 93.4% ( P = 0.67). CONCLUSIONS This initial 3‐year analysis showed that cT1a has comparable oncological PN; however, longer term data are still needed.
