The purpose of this study is to determine whether or not there are more complications in the extraperitoneal compared with the transperitoneal approach for laparoscopic aortic lymphadenectomy for the surgical staging of endometrial or ovarian cancer

STELLA 2 Trial: Staging of Endometrial and Ovarian Cancer Comparing the Transperitoneal vs. Extraperitoneal Approach for Laparoscopic Lymphadenectomy of Aortic Nodes, Evaluating Complications

Composite outcome defined by including at least one of the following:

* Total estimated blood loss \> 500 mL during surgery
* Blood transfusion
* Intraoperative complication classified as Dindo grade III or worse, related to the aortic lymphadenectomy
* Early postoperative complication (within 30 days after surgery) classified as Dindo grade III or worse, related to the aortic lymphadenectomy
* Late postoperative complication (past 30 days after surgery) classified as Dindo grade III or worse, related to the aortic lymphadenectomy
* Conversion to laparotomy during the aortic lymphadenectomy
* Inability to complete the aortic lymphadenectomy

The number of lymph nodes (absolute number) is specified by the pathologist on histopathological analysis of the sample sent by the surgeon after surgical staging is realized (laparoscopic aortic lymphadenectomy). This variable is subdivided into: supra-mesenteric and infra-mesenteric.

Total duration of surgery (from initial skin incision to end of skin suture), and total aortic lymphadenectomy time (time spent since the beginning of aortic lymphadenectomy to its completion). Metric: minutes.

The number of days that patients stay in the hospital after surgery, measured in days from the day of the surgery to the day the patient is discharged from the hospital.

Period of time in which there is no appearance of the symptoms or effects of the disease.

Both laparoscopic partial nephrectomy (LPN) and robotic partial nephrectomy (RPN) can be performed through transperitoneal (TP) or retroperitoneal (RP) approach. RP approach is less utilized than TP approach because of technical difficulties when using rigid laparoscopic instruments in the small space of retroperitoneum cavity. However, with advanced surgical skills and thoughtful patient selection, RP approach may be associated with shorter operative time (OT), less estimated blood loss (EBL), shorter length of hospital stay (LOS) compared with TP approach.

Therefore, the investigators performed randomized control trial to compare the outcomes of the two approaches (TP-LPN or RPN vs RP-LPN or RPN).

Partial nephrectomy is the standard treatment for small renal masses. The evolution of minimally invasive partial nephrectomy led to widespread utilization of laparoscopic (LPN) and robotic partial nephrectomy (RPN). Both LPN and RPN can be performed through transperitoneal (TP) or retroperitoneal (RP) approach. RP approach is less utilized than TP approach because of technical difficulties when using rigid laparoscopic instruments in the small space of retroperitoneum cavity. However, with advanced surgical skills and thoughtful patient selection, RP approach may be associated with shorter OT, less EBL, shorter LOS compared with TP approach.

Therefore, the investigators performed randomized control trial to compare the outcomes of the two approaches (TP-LPN or RPN vs RP-LPN or RPN).

The purpose of this study To compare the treatment outcomes of the transperitoneal and retroperitoneal approach during LPN or RPN in treatment of small renal masses.

Inclusion criteria During the study period, a small renal mass (less than 4cm, T1a stage) patients are going to underwent LPN or RPN.

Exclusion criteria

1. Patients who underwent radical nephrectomy
2. Patients with bilateral renal masses
3. Patients with a solitary kidney
4. Patients reject a written informed consent
5. Pregnancy

The number of target subjects More than 106 patients who meet the inclusion criteria
