Single-port robot-assisted retroperitoneal partial nephrectomy: First European case series.

Abstract

Introduction: Single port robotic assisted retroperitoneal partial nephrectomy (SPRA-PN) represents a novel minimally invasive approach in urology. This study aims to present the first European case series of SPRA-PN, describing the initial experience, patient outcomes and potential benefits of this technique.

Patients and methods: This prospective study included patients scheduled for retroperitoneoscopic surgery between 22nd February 2022 and 6th June 2023. All procedures were performed using the da Vinci Xi® surgical system with a single-port access technique. Patient demographics, operative details, complications and post-operative outcomes were recorded. Cosmetic satisfaction was assessed using the Patient Scar Assessment Questionnaire.

Results: Ten patients underwent SPRA-PN. Technical success was achieved in all cases, with no conversions to open surgery or additional ports required. The mean console time was 84.2 min, and the mean ischaemia time was 19.5 min. Post-operative pain remained low, with a mean visual analogue scale (VAS) of 2.5 at 48 h post-surgery. Positive margins were found in one case. Cosmetic satisfaction was reported to be high among patients.

Conclusion: This initial case series demonstrates the feasibility and potential benefits of SPRA-PN using the da Vinci Xi platform in Europe. Further research is warranted to evaluate long-term outcomes and the widespread applicability of SPRA-PN.
