Transperitoneal Versus Retroperitoneal Single-port Robotic-assisted Partial Nephrectomy: An Analysis from the Single...

Area of Science:

• Urology
• Minimally Invasive Surgery
• Robotic Surgery

Background:

• Single-port (SP) robotic-assisted partial nephrectomy (RAPN) is an emerging technique for kidney tumor management.
• The transperitoneal (TP) and retroperitoneal (RP) approaches are utilized for SP RAPN, but comparative outcome data are limited.

Purpose of the Study:

• To compare the perioperative and postoperative outcomes of the TP versus RP approaches in SP RAPN.

Main Methods:

• A retrospective cohort study analyzed data from the Single Port Advanced Research Consortium (SPARC) database (2019-2022).
• 219 patients undergoing SP RAPN for renal masses were compared between TP and RP groups.
• Statistical analyses included chi-squared test, Fisher exact test, Mann-Whitney U test, and Student t test.

Main Results:

• No significant differences were observed in ischemia time, operative time, estimated blood loss, length of stay, or overall/major complication rates between TP and RP groups.
• Posterior tumors were more common in the RP group (p < 0.001), but other baseline characteristics were comparable.
• Positive surgical margin rates and estimated glomerular filtration rate (eGFR) changes at 6 months were similar for both approaches.

Conclusions:

• Both the TP and RP approaches are viable options for SP RAPN.
• Patient and tumor characteristics should guide the selection of the TP or RP approach to ensure satisfactory surgical outcomes.
