An early experience of the robot-assisted laparoscopic nephroureterectomy without re-docking in a single position.

OBJECTIVE

This study aims to evaluate the execution of robot-assisted laparoscopic nephroureterectomy without repositioning the patient.

METHODS

The clinical data of 9 patients who underwent robot-assisted laparoscopic nephroureterectomy between May 2017 and November 2018 were analyzed, proceeding in a single position, without repositioning the patient. This involved 5 men and 4 women, with an average age of 61.67 ± 10.37 years and an average body mass index (BMI) of 24.78 ± 3.84. We considered the duration of the intervention, the blood loss, the duration of the hospital stay, the duration of maintenance of the drainage and the follow-up on all patients, with or without complications and recurrence of the tumor.

RESULTS

The intervention was completed in all 9 cases. The average duration of the intervention was 242.89 ± 13.37 minutes, the average blood loss was 166.67 ± 70.71 ml, the average hospitalization time was 2 ± 0.71 days, the average time drainage maintenance was 5.11 ± 1.05 days and the average follow-up times without complications and tumor recurrence were 12.56 ± 6.19 months.

CONCLUSION

Robot-assisted laparoscopic nephroureterectomy without repositioning the patient during the procedure simplifies the procedure and shortens the duration of the procedure. It is also a safe, effective and feasible minimally invasive treatment method.
