Conservative surgery in renal adenocarcinoma has originated a growing interest over the last few years for several reasons: 1. Refinement in renal imaging techniques. 2. Improvement in surgical techniques. 3. Greater number of tumours discovered incidentally usually at low stage, and 4. Good long-term results in patients treated this way. We conducted a retrospective analysis of 8 patients diagnosed with renal adenocarcinoma and treated with conservative surgery over a 5-year period, between January 85 and December 90. Complete tumour removal by enucleation was achieved in all patients, with low morbidity rates since only 1 patient had to be re-operated due to late haemorrhage. Since follow-up is short in most patients, no long-term results are provided. We conclude that enucleation is a simple technique which allows complete removal of small size renal adenocarcinoma with low morbidity and no mortality.
