Use of the habib 4× radiofrequency-assisted bipolar hemostatic device to avoid warm ischemia in select large partial nephrectomies: Description and video of technique

Objectives: The Habib 4 × radiofrequency-assisted bipolar hemostatic device (AngioDynamics) was used during select open partial nephrectomies to minimize blood loss and prevent warm renal ischemia. The article and video demonstrate this novel technique for partial nephrectomies in select renal masses. Methods: Patients with large renal tumors requiring partial nephrectomy where avoidance of warm ischemia was deemed imperative underwent open partial nephrectomy at our institution utilizing the Habib 4 × radiofrequency ablation device to avoid prolonged warm ischemia time and prevent blood loss. Results: We have used the device successfully in 4 partial nephrectomies (2 patients with solitary kidneys, 2 patients with bilateral large masses). The mean age was 65 years. Mean tumor size was 6.4 cm. All tumors were located either in the upper pole or lower pole of the kidney. Mean hospital stay was 4.6 days. No patient received an intraoperative blood transfusion. Two patients required long-term ureteral stenting and surgical drainage for urine leakage. Conclusions: Bipolar radiofrequency ablation offers avoidance of hilar clamping in carefully selected large partial nehrectomies.
