Background:

Kidney cancer accounts for 2% of cancer deaths in Mexico. Partial nephrectomy has become the treatment of choice for renal tumors <4cm and can be carried out utilizing minimally invasive techniques.

Aim:

To describe the perioperative, oncologic, and follow-up characteristics of patients that underwent partial laparoscopy with the robotic-assisted or laparoscopic approach at our hospital center.

Methods:

A descriptive, retrospective cases series was conducted on patients that underwent minimally invasive partial nephrectomy at the Centro Médico Naval, within the time frame of February 2016 to February 2019.

Results:

Sixteen patients had a BMI >25 kg/m2, initial creatinine was 0.97mg/dl, surgery duration was 202 minutes, blood loss was 300 ml, and 13 patients underwent warm ischemia, for a median of 24 minutes. Hospital stay was 3 days, 2 patients presented with complications, and serum creatinine at day 30 was 1.05 mg/dl. The 17 patients that presented with cancer all had clear cell renal cell carcinoma. Thirteen of those patients had nuclear grade 2 and 3 had positive margins.

Conclusions:

Our good short-term oncologic and functional results were similar to those reported in the international literature. Comparison with the national literature is difficult, given the lack of studies employing the robotic approach.
