Carbon dioxide creates abdominal working space by gently expanding the operative field around the kidney. This space allows the camera and specialized instruments to function through the multichannel port while giving the surgeon room to visualize and manipulate tissue. Maintaining this working environment is essential for performing the dissection and vessel and ureter management through one access site.
The multichannel port provides a shared entry point for the camera and specialized instruments. Their coordinated use lets surgeons view the operative field while isolating, sealing, and dividing the renal blood vessels and ureter. This arrangement concentrates access through one incision but aims to preserve the visualization and instrument control associated with laparoscopic or robotic surgery.
The operation requires careful isolation followed by sealing and division of the renal blood vessels and ureter before the kidney is removed. Managing these structures in a controlled sequence supports safe separation of the kidney from its connections. This step is central to completing the resection while maintaining the precision expected from minimally invasive visualization and instrument control.
Its principal distinction is the access strategy: the kidney is reached through one small incision rather than an open incision or several laparoscopic access points. The approach may reduce abdominal scarring while retaining camera-based visualization and specialized instrument control. It therefore represents an alternative technique when the surgical indication and operative circumstances are appropriate.
The surgeon first establishes abdominal working space with carbon dioxide and places a multichannel port through the single incision. Using the camera and instruments, the renal blood vessels and ureter are identified, isolated, sealed, and divided. The kidney is then extracted through the access site. These steps combine exposure, controlled separation, and specimen removal within one operative pathway.
The technique can be used for kidney tumors, severely nonfunctioning kidneys, and selected living-donor procedures. These applications reflect different clinical reasons for removing a kidney, but all require the surgeon to complete vascular and ureteral management before extraction. The choice of approach depends on whether the case is suitable for the single-port method described.
Selected living-donor cases are among the reported applications of this minimally invasive approach. In that setting, the operation combines kidney removal with the access and visualization principles of single-port surgery. Its potential to limit abdominal scarring, while preserving laparoscopic or robotic instrument control, provides a surgical rationale for considering the technique in appropriate donor procedures.
