Introduction: To perform nephron-sparing surgery, arterial clamping is often required. Operative bleeding control is difficult in laparoscopic techniques. We imagined a novel technique for "zero ischemia" nephron-sparing surgery using a hybrid opearating room: clampless laparoscopic partial nephrectomy was performed after superselective tumoral embolization. Our objective is to describe this new technique.

Methods: The patient is a 46 year old patient with no prior medical history, who had a 3 cm large localized renal tumor on the convexity of the left kidney. The lesion was heterogeneous, medial, partially endophytic and of moderate complexity (RENAL 8p). The procedure was realized in a hybrid operating room by a double team: interventional radiologist and urologist.

Results: A first renal arteriography was made to visualize the arterial vascularization of the left kidney. With a guidance software, the tumoral artery was catheterized superselectively. The tumor and its arteries were embolized by microspheres and coils. A 3D arteriography showed the exclusion of the tumor from the renal vascularization. Then, the patient was positionned for laparoscopic partial nephrectomy, thas was performed without dissecting the renal pedicule, nor clamping of the renal artery. Operative bleeding was insignificant. No suture was necessary. A final control 3D arteriography showed no arterial bleeding and preservation of healthy renal parenchyma. Follow-up was uneventful. Preoperative renal function was maintained. The tumor was a clear cell renal carcinoma. Surgical margins were negative.

Conclusions: This is the first experience of superselective tumoral embolization followed immediately by laparoscopic partial nephrectomy in a hybrid operating room. Resection of a localized renal cancer of moderate complexity was performed clampless, sutureless and without intraoperative bleeding.
