Robot-Assisted Laparoscopic Radio Frequency Ablation Assisted Enucleation of Renal Cell Carcinoma With T1a Stage

Robot-Assisted Laparoscopic Radio Frequency Ablation Assisted Enucleation of Renal Cell Carcinoma With T1a Stage : Clinical Outcomes of a Randomised Controlled Trial

To evaluate the feasibility and efficiency of zero ischemia robot-assisted laparoscopic radio frequency ablation assisted enucleation of T1a renal cell carcinoma in comparison with robot-assisted laparoscopic partial nephrectomy without hilar clamping.

Inclusion Criteria:

• patients with sporadic, unilateral, newly diagnosed T1a presumed renal cell carcinoma
• patients scheduled for robot-assisted laparoscopic nephron sparing surgery
• patients with normal contralateral renal function (differential renal function of >40% as determined by radionuclide scintigraphy)
• patients agreeable to participate in this long-term follow-up study

Exclusion Criteria:

• patients' aged >80 years
• patients with other renal diseases,(including kidney stone, glomerular nephritis, etc.) which might affect the renal function of the operative kidney
• patients not able to tolerate the robot-assisted laparoscopic procedure
• patients with previous renal surgery or history of any inflammatory conditions of the operative kidney
• patients with the renal tumor involving urinary collecting system
