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.",[9],null,{"type":22,"name":28,"description":28,"armGroupLabels":29,"otherNames":26},"robotic-assisted laparoscopic partial nephrectomy",[15],[31,36],{"name":32,"role":33,"phone":34,"phoneExt":26,"email":35},"Jiwei Huang, PhD.","CONTACT","02168383204","huangjiwei@renji.com",{"name":37,"role":33,"phone":38,"phoneExt":26,"email":39},"Yiran Huang, MD.","+8613501835219","huangyrrenji@163.com",[41],{"facility":42,"status":43,"city":44,"state":26,"zip":26,"country":45,"countryCode":46,"cosmosGeoPoint":47,"geoPoint":52,"contacts":53},"Ethics Committee of Shanghai Renji Hospital","RECRUITING","Shanghai","China","CN",{"type":48,"coordinates":49},"Point",[50,51],121.45806,31.22222,{"lat":51,"lon":50},[54],{"name":55,"role":33,"phone":56,"phoneExt":26,"email":57},"Qi Lu","+86021-68383364","rjllb3364@163.com",{"type":59,"investigatorFullName":26,"investigatorTitle":26,"investigatorAffiliation":26,"oldNameTitle":26,"oldOrganization":26},"SPONSOR","100571102","zero-ischemia-robot-assisted-mwa-assisted-suture-less-tumor-enucleation-of-rcc-with-t1-stage-100571102",false,"NCT06715878","Zero Ischemia Robot-Assisted MWA Assisted Suture-less Tumor Enucleation of RCC With T1 Stage","Zero Ischemia Robot-Assisted Microwave Ablation Assisted Suture-less Enucleation of Renal Cell Carcinoma With T1 Stage: A Randomized Clinical Trial","Inclusion Criteria:\n\n1. patients with sporadic, unilateral, newly diagnosed T1 presumed renal cell carcinoma\n2. patients scheduled for robot-assisted laparoscopic nephron sparing surgery\n3. patients with normal contralateral renal function (differential renal function of \\>40% as determined by radionuclide scintigraphy)\n4. patients agreeable to participate in this long-term follow-up study\n\nExclusion Criteria:\n\n1. patients' age \\>80 years\n2. patients with other renal diseases (including kidney stone, glomerular nephritis, etc.)which might affect the renal function of the operative kidney\n3. patients not able to tolerate the robot-assisted laparoscopic procedure\n4. patients with previous renal surgery or history of any inflammatory conditions of the operative kidney\n5. patients with the renal tumor involving urinary collecting system or distance from the tumor edge to the collecting system ≤ 4 mm","ALL","15 Years","80 Years",{"count":71,"type":72},80,"ESTIMATED","INTERVENTIONAL",[75],"NA","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.
