The present study describes the technical feasibility of a combined-modality angiography/computed tomography (angio-CT)–assisted balloon dissection technique for bowel protection during renal cryoablation in six procedures in five patients. A retrospective review was performed to evaluate balloon dissection using the angio-CT system. Mean bowel-to-tumor distances before and after balloon dissection were 0.9 mm (range, 0–3 mm) and 13.0 mm (range, 11–17 mm), respectively. No bowel injury was observed during the mean follow-up period of 19 months (range, 7–44 mo). Our preliminary experience suggests that balloon dissection using the angio-CT system for bowel protection during renal cryoablation may be feasible and effective.
