Savannah Grandy, DO, highlights study of single-port vs multiport RPN

In this video, Savannah Grandy, DO, outlines the background and key findings from the study, “Initial comparison of single port (SP) vs. multiport (Xi) robotic partial nephrectomy in MUSIC-KIDNEY,” which she presented at the 2026 Desai Sethi Urology Institute Urology on the Beach meeting in Miami Florida. Grandy is a PGY-5 urology resident at McLaren Macomb in Mount Clemens, Michigan.

Grandy began by discussed the background for a study comparing single-port and multiport surgical approaches, which stemmed from increasing use of single-port surgery within her program at Henry Ford Macomb. Working within a regional consortium, the team sought to collect early, real-world data from multiple surgeons across Michigan. The goal was to assess whether outcomes with the single-port approach were comparable to, better than, or worse than those achieved with traditional multiport techniques.

The study’s findings showed several advantages associated with single-port surgery. Compared with multiport cases, single-port procedures were linked to shorter operative times, lower estimated blood loss, and a higher likelihood of same-day (postoperative day zero) discharge. Single-port cases were also more frequently performed via a retroperitoneal approach and were associated with improved postoperative pain control and fewer opioid prescriptions at discharge.

Looking ahead, Grandy noted the potential for a follow-up study using updated data. Since several years have passed and the participating surgeons have gained substantially more experience with single-port procedures, she believes a repeat analysis could yield even stronger results. Re-examining outcomes within the same cohort of surgeons may help clarify how increasing familiarity with the technique further impacts performance and patient outcomes over time.
