Introduction: The retroperitoneoscopic approach is advantageous from the point of view of its minimal invasiveness, on the other hand, its disadvantage is the limited space, which can make the actual surgical preparation and treatment of the resection area technically more difficult.
Material and methods: In the video presentation, we show the case of a 57-year-old man with abdominal obesity (120 kg, BMI 40), who was diagnosed with a 6 cm tumor on the dorsal side of the convexity of the upper pole of the right kidney based on ultrasonography and subsequent CT examination (RENAL score 9p). The tumor was successfully removed by robotically assisted retroperitoneal resection with minimal blood loss and without intraoperative and postoperative complications.
Conclusion: The retroperitoneoscopic approach is advantageous in the case of a kidney-sparing procedure in the presence of dorsally placed kidney tumors, especially in obese patients and patients after previous operations in the peritoneal cavity.
