OBJECTIVES To determine the feasibility and safety of performing percutaneous cryoablation of angiomyolipomas (AMLs) in patients with solitary kidneys. METHODS Three 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(More)
PURPOSE Patients with ESRD secondary to acquired renal cystic disease have been reported to have a higher incidence of RCC than the general population. We examined the clinical and pathological significance of incidental renal masses in patients with ESRD. MATERIALS AND METHODS From January 1994 to July 2000, 852 consecutive patients with ESRD who were(More)
PURPOSE Ablative treatments (cryoablation or radio frequency ablation) for renal cell carcinoma aim to decrease morbidity by treating renal tumors in situ, eliminating the need for extirpation. These technologies have potential for complications previously unassociated with renal tumor treatment. We identified complications associated with percutaneous and(More)
To discuss the use of renal mass biopsy (RMB) for small renal masses (SRMs), formulate technical aspects, outline potential pitfalls and provide recommendations for the practicing clinician. The meeting was conducted as an informal consensus process and no scoring system was used to measure the levels of agreement on the different topics. A moderated(More)
OBJECTIVES To determine the feasibility of replacing a ureteral segment with a neointimized Gore-Tex graft. METHODS Seven adult mongrel dogs underwent a two-stage operative procedure. The first procedure involved arterializing the graft to stimulate spread of a luminal neoendothelium by transmural capillary growth. Eight weeks after the initial procedure,(More)
PURPOSE We determine the feasibility and safety of performing percutaneous cryoablation of renal tumors in patients with von Hippel-Lindau disease. MATERIALS AND METHODS We selected 2 men and 2 women with von Hippel-Lindau disease and radiographic determined solid renal tumors were selected to undergo percutaneous cryoablation. All patients underwent(More)
PURPOSE Cryoablation of small renal tumors has been performed mainly via the laparoscopic or open approach. This study was done to assess the feasibility and safety of performing percutaneous renal tumor cryoablation using interventional magnetic resonance imaging (MRI) for monitoring. MATERIALS AND METHODS Patients with radiography documented small renal(More)
Anomalies of the inferior vena cava arise infrequently. Knowledge of their presence can be established preoperatively with a variety of radiologic studies. This knowledge can prevent hemorrhagic complications from occurring during surgery. We present a case report of a patient with renal cell carcinoma and duplication of the inferior vena cava.
BACKGROUND AND PURPOSE Surgical management of a renal neoplasm in a solitary kidney is a balance between oncologic control and preservation of renal function. We analyzed patients with a renal mass in a solitary kidney undergoing nephron-sparing procedures to determine perioperative, oncologic, and renal functional outcomes. PATIENTS AND METHODS A(More)
