Percutaneous radiofrequency ablation of an actively bleeding renal angiomyolipoma.

We report a case of computed tomography-guided percutaneous radiofrequency ablation of a bleeding renal angiomyolipoma. Radiofrequency ablation was performed as an alternative to partial nephrectomy and super-selective renal artery embolization for ruptured renal angiomyolipoma with slow persistent bleeding in a patient with elevated serum creatinine levels and other comorbidities. Computed tomography-guided radiofrequency ablation successfully stopped the active hemorrhage and did not affect long-term renal function during the 3-year follow period.

Prospective comparative study between retroperitoneoscopic and hand-assisted laparoscopic approach for radical nephrectomy.

Objective: No consensus has yet been established regarding the best minimally invasive access for radical ablation of renal tumors. Our objective was to prospectively compare the surgical results and oncologic management of two currently used endoscopic techniques.

Materials And Methods: Over a four-year period, 50 patients with renal tumors and clinical stage T1b-T2, smaller than 12 cm, underwent a radical nephrectomy at two reference institutions, 25 underwent retroperitoneoscopic radical nephrectomy (RRN) and 25 a hand-assisted laparoscopic radical nephrectomy (HALRN).
