ObjectivesTo determine the feasibility and safety of performing percutaneous cryoablation of angiomyolipomas (AMLs) in patients with solitary kidneys.MethodsThree patients with AMLs involving a solitary kidney underwent computed tomography-guided percutaneous cryoablation. All lesions were located in the lateral/posterior part of the kidney, allowing for safe access from the skin for cryoprobe insertion. Intravenous sedation and local anesthesia were used for each patient. Follow-up computed tomography or magnetic resonance imaging and physical examination, urinalysis, and serum blood urea nitrogen/creatinine measurement were performed to evaluate for lesion recurrence and to evaluate the safety profile.ResultsThree tumors (1.2-2.5 cm) were treated. The patients experienced minimal to no pain during percutaneous cryoablation, and all were discharged the same day. No procedural or postoperative complications were noted. During the follow-up period (5-36 months), the first 2 patients had no radiographic evidence of recurrence. Initial follow-up imaging of the third patient displayed persistent AMLs.ConclusionsA review of the published data suggested the necessity to prophylactically treat AMLs of solitary kidneys. In this series, percutaneous cryoablation proved a safe and effective method for treating these lesions. This ultimately provides a minimally invasive option for similar patients, potentially avoiding an open surgical procedure or the risk of hemorrhage.
