Suggested techniques and strategies from round 1

Prior to tumor resection	During tumor resection	During renorrhaphy
Clamping artery + vein vs. artery alone Controlled hypotension Robotic vs. lap Discontinuation of anti-platelet agents Antifibrinolytics En-bloc clamping vs. bulldogs Intraoperative doppler for flow Newly suggested: Renal mobilization and hilar dissection Selective arterial clamping Adequate pneumoperitoneum Prior suture preparation	Enucleation Early clipping of vessels Reducing resection margin to tumor (staying close to tumor) Increasing pneumoperitoneum Electrocautery of resection bed Electrocautery resection Argon beam coagulator Ultrasonic/harmonic Newly suggested: Assistant to apply pressure Unclamping vein if bleeding	Barbed stitch/Vloc Fibrin glue/sealants (Tisseel, Evicel) Gelatin thrombin agents (Floseal, Surgiflo) Oxidized cellulose polymer (Surgicel, Surgifoam) Hemostatic patch (Hemopatch) Bolster Placing clips over knot tying Re-approximation of Gerota’s fascia Placement of a drain Newly suggested: Early unclamping and suture ligate arterial bleeders
