Ureteral protection during microwave ablation of renal cell carcinoma: combined use of pyeloperfusion and hydrodissection

Özet

A 56-year-old female with past medical history of thrombotic microangiopathy presented to herphysician with nonspecific abdominal pain. A magnetic resonance imaging scan was obtained,which revealed a 3.1 cm mass arising from medial lower pole of the left kidney that was subsequently shown to be renal cell carcinoma by percutaneous biopsy. Because of her history ofthrombotic microangiopathy and other comorbidities, she was deemed a nonsurgical candidateand was therefore referred to interventional radiology for thermal ablation. Computed tomography (CT)-guided microwave ablation was performed with the combined use of pyeloperfusionand hydrodissection for maximal ureteral protection. Follow-up unenhanced CT scan obtainedone month after ablation showed a normal collecting system without evidence of hydronephrosis or urinoma.
