Single-port robot-assisted partial nephrectomy (SP-RAPN) shows promise but has longer ischemia times and higher transfusion rates than multiport robot-assisted partial nephrectomy (MP-RAPN). Further research is needed to optimize SP-RAPN

Area of Science:

  • Urology
  • Minimally Invasive Surgery
  • Robotic Surgery

Background:

  • Single-port robot-assisted partial nephrectomy (SP-RAPN) is an emerging technique.
  • Its comparative outcomes against multiport robot-assisted partial nephrectomy (MP-RAPN) require evaluation.

Approach:

  • A meta-analysis was conducted comparing SP-RAPN and MP-RAPN outcomes.
  • Literature search of PubMed, Scopus, and Web of Science up to January 2023.
  • Included 8 studies with 1007 partial nephrectomy cases.

Key Points:

  • SP-RAPN demonstrated longer ischemia time (4.6 min) and higher transfusion rates (OR 2.97) versus MP-RAPN.
  • SP-RAPN showed less estimated blood loss (-12.4 mL) and higher 6-month eGFR (4.9 mL/min).
  • No significant differences in complications, positive margins, or hospital stay were observed.

Conclusions:

  • SP-RAPN is a safe and feasible approach for partial nephrectomy.
  • Current data suggest inferior ischemia time and transfusion rates compared to MP-RAPN.
  • Further studies are needed to establish optimal use of SP-RAPN.
