Robot-assisted laparoendoscopic single-site surgery (LESS) for partial nephrectomy using a homemade port is safe and feasible. This technique allows for precise suturing and good surgical field access.

Area of Science:

  • Urology
  • Minimally Invasive Surgery
  • Robotic Surgery

Background:

  • Partial nephrectomy is a standard treatment for renal cell carcinoma.
  • Robotic-assisted laparoendoscopic single-site surgery (LESS) offers potential advantages in minimally invasive procedures.
  • Novel port systems are being developed to facilitate LESS techniques.

Purpose of the Study:

  • To evaluate the safety and feasibility of robot-assisted LESS for partial nephrectomy.
  • To assess the efficacy of a hybrid homemade port system for LESS partial nephrectomy.
  • To analyze outcomes including operative time, complications, and oncologic results.

Main Methods:

  • A retrospective analysis of 14 patients undergoing robot-assisted LESS partial nephrectomy for renal cell carcinoma.

  • Utilized a hybrid homemade port system for surgical access.
  • Collected data on patient demographics, operative details, complications, and pathological findings.

    • Main Results:

    • The mean tumor size was 3.2 cm, with a mean operative time of 233 minutes and ischemic time of 30 minutes.
    • The hybrid homemade port was used in 10 cases.
    • All patients achieved negative surgical margins; no port-related complications occurred, though two cases required conversion to mini-incisional surgery.

    Conclusions:

    • Robot-assisted LESS partial nephrectomy with a hybrid homemade port is a safe and feasible technique.
    • The articulating robot arms facilitate meticulous suturing of renal parenchyma.
    • This approach provides excellent surgical field access for the assistant surgeon.
