Percutaneous Cryoablation of the Horseshoe Kidney: An Initial Experience.
Between June 2006 and January 2016, 6 renal cryoablation procedures were performed in 5 patients with horseshoe kidneys. Renal cell carcinoma (RCC) accounted for 5 of the tumors, and the sixth was a carcinoid tumor. All 6 procedures were technically successful. The patient with the carcinoid tumor developed local tumor progression 38 months after ablation. Technique effectiveness was achieved in all 5 patients with RCC. Two complications occurred: obstructive hematuria and transient inguinal neuralgia after ablation. In this small initial experience, percutaneous cryoablation appears feasible in treatment of primary tumors in horseshoe kidneys.
