Aims and objectives
Radiofrequency ablation is used since more than 15 years in the treatment of T1a (< 4cm) renal tumours1.
It allows to preserve long-term kidney function with favourable oncological outcomes.
The incidental detection of renal cell carcinoma is increased by use of MRI and CT scanner2.
Renal tumours close to the collecting system is a major risk factors of radiofrequency ablation complication in the literature3.
It’s also an important criteria for partial nephrectomy included in Renal score.
Some algorithms have been proposed for planning the percutaneous procedure as ABLATE score4 or P-RAC5 score which take into account the renal tumours proximity from pyelocaliceal cavity and ureter.
Different technics are used to protect urinal tract such as water cooling6 or hydrodissection7.
The purpose of our study was to evaluate the feasibility and the safety of urinal tract thermal protection during radiofrequency ablation (RFA) of central renal tumours close to the urinary tract with room air dissection.
