Methods and materials
It was a retrospective monocentric study including consecutive patients having a T1a central renal tumour with urinary tract contact (pelvis kidney or proximal ureter).
All the treatment options were validated by a multidisciplinary board and informed consent was obtained for all patients .
All procedures were performed with CT guidance (GE lightspeed) using RFA (Leveen needles) under general anaesthesia.
Aerodissection was performed with room air injected through a 22 G needle placed close to the urinary tract.At the beginning of the procedure 2 ml of room air were injected carefully with CT control in order to avoid vascular embolization (fig 1).
Technical success was defined when an adequate isolation of urinary tract from the needle was obtained (fig 2).
Complications were collected and graded following the CTCAE classification.
Patients had a follow up at 6 weeks,
6 months and then annually by abdominal MRI and medical consultation.
