Overview
Aim:
Evaluation of clinical experience with percutaneous RFA of kidney tumours in the period 2006–2008 and indication for this method.
Material and methods:
Overall 36 kidney tumours in 33 patients were enrolled to the prospective study; 53 RFA operations were carried out. The operation was done by the Star-Burst instrument (RITA Medical system) under CT control under a local anaesthesia. Patients were admitted for a one day hospitalisation. Indications for RFA were serious comorbidities contraindicating open surgery, tumour in anatomically or functionally solitary kidney and tumours in chronicaly insuffitient kidneys. Check-up of renal functions, chest X ray and local tumour kontrol (loss of its opacification and retraction of surrounding tissue on CT with kontrast medium) were used to provide in all patients. Mean follou-up time was 18 months.
Results:
One step RFA was successful at 24 tumours (66.66%), the reRFA in 6 month for 12 residues was successful for 7 times (86.1% out of total number of tumours ) and rereRFA in next 6 month was partial successful (partial ablation) at remaining tumor residues. Four patients died (the two from the metastatic tumour, the one from chronic renal insufficiency, the one from comorbidities).
Conclusion:
The percutaneous RFA is considered to be a suitable miniinvasive Alternative method of an ablative treatment of a kidney tumour up to size of 4 cm by prenomiate group of patients.
Key words:
kidney tumours, radiofrequency ablation (RFA).
