Zero Ischemia Robot-Assisted MWA Assisted Suture-less Tumor Enucleation of RCC With T1 Stage
Sponsor: RenJi Hospital
Summary
Zero ischemia laparoscopic radio frequency ablation assisted tumor enucleation has been proved to enable tumor excision with relatively better renal function preservation comparing with conventional laparoscopic partial nephrectomy for T1a renal cell carcinoma (RCC) in a randomized clinical trial in single center. The investigators want to explore this technique to robotic surgery and add suture-less technique to T1 RCC patients in randomized clinical trial.

Zero Ischemia Robot-Assisted Laparoscopic Microwave Ablation Assisted suture-less Enucleation
Under the visualization of ultrasound contrast imaging through the operative channel, a microwave ablation probe was inserted into the tumor (at the interface between the tumor and kidney, close to the tumor base). The microwave ablation device was used, with a power setting of 70 W for initiating microwave ablation. Depending on the tumor volume and depth, 1-3 ablation cycles were performed, with each cycle lasting 1-3 minutes. After reaching the pseudocapsule of the tumor, a combination of blunt dissection, sharp cutting, and blunt dissection was employed to separate the tumor from the renal parenchyma . The renal artery was not occluded during the procedure.If intraoperative injury to the collecting system is suspected, the collecting system should be sutured normally, while simultaneously suturing the outer layer of renal parenchyma to prevent urine leakage.
