Experimental: Robot assisted partial nephrectomy super-selective clamping
The Da Vinci robot (device) allows to use near-infrared fluorescence in order to clamp precisely the branches of the vascularization for the partial nephrectomy. The healthy parenchyma ischemia is avoided.
Procedure: Robot assisted partial nephrectomy super-selective clamping
The device used to performe the surgery is a Da Vinci robot. After injection of infracyanine, the super-selective clamping is possible. The surgery is performed using a specific clamping of the tumor arteries. Super-selective ischemia is checked using near infrared fluorescence.
Other Name: Robot assisted zero-ischemia partial nephrectomy with the Da Vinci robot (device)
Active Comparator: Robot assisted partial nephrectomy with renal artery clamping
The partial nephrectomy with robotic assistance is performed using a renal artery. It's the conventional method.
Procedure: Robot assisted partial nephrectomy with renal artery clamping
Partial nephrectomy is performed with the conventional method in wich a renal artery clamping is done.
Other Name: Robot assisted partial nephrectomy with conventional method
- Benefit on postoperative renal function of fluorescence-enhanced super-selective clamping during robot assisted partial nephrectomy compared with robot-assisted partial nephrectomy with renal artery clamping [ Time Frame: 6 months ]The glomerular filtration rate (GFR) of the kidney operated is assessed at 6 months after surgery. This value is compared to that assessed before the surgery to see the variation. This variation is compare between the two groups.
- Number of group conversion in the zero ischemia method. [ Time Frame: 6 months ]The feasibility of the new technique is assessed by counting the number of group conversion towards conventional technique.
- Surgical duration in the two groups [ Time Frame: 6 months ]Duration between the first incision and the skin closure
- Complications [ Time Frame: 1 month ]number of complications per and post-surgery up to 1 month
- Per-surgery blood loss [ Time Frame: 1 month ]per-surgery blood loss in millimeter
- Hemoglobine rate variation [ Time Frame: 1 month ]For patients having no received blood transfusion, the hemoglobine rate variation is assessed in percentage at one month in post-surgery.
- Positive surgical margins [ Time Frame: 1 month ]Number of positive surgical margins
- Variation between global GFR in the two groups [ Time Frame: 6 months ]The variation of the global GFR is assessed after surgery, when patient is discharged. This value is compared to the that collected before the surgery.
- Renal parenchyma preserved [ Time Frame: 6 months ]The percentage of renal parenchyma preserved is evaluated by CT renal volumetry at 6 months after the surgery. The value is compared to that collected before the surgery.
