Researchers recently conducted a prospective randomized study to evaluate the SR2000 robotic surgical system against the industry-standard Da Vinci Xi. The study focused on patients undergoing robot-assisted partial nephrectomy (RAPN). Consequently, the results provide critical insights for urologists considering domestic robotic platforms as viable alternatives to established systems.
The analysis included 90 patients randomized between the two surgical systems. Notably, the researchers found no significant differences in docking time, operative time, length of hospital stay, or intraoperative blood loss. All 90 procedures were completed successfully without converting to open or traditional laparoscopic surgery. Additionally, every patient achieved negative surgical margins, ensuring high standards of oncological safety.
One of the most significant findings involves the transition process for experienced robotic surgeons. While many doctors already use the Da Vinci Xi, switching to a new platform often requires specific technical adjustments. The study suggests that Da Vinci-proficient surgeons need about 18 cases to master the SR2000 robotic surgical system.
Furthermore, the domestic group recorded a 23-minute warm ischemia time versus 24 minutes in the Da Vinci group. Although this difference was not statistically significant, it demonstrates that the domestic robot performs reliably during the most critical phases of nephron-sparing surgery. Therefore, the SR2000 appears both safe and effective for complex renal procedures. Its comparable performance metrics suggest it could play a major role in expanding access to robotic urological care.
For surgeons already experienced with the Da Vinci Xi platform, this study indicates that technical proficiency with the SR2000 system is typically achieved after approximately 18 cases.
Yes, the clinical trial showed that both systems had comparable safety profiles. There were no statistically significant differences in blood loss, complication rates, or the achievement of negative surgical margins.
The SR2000 group had a mean warm ischemia time of 23 minutes, compared to 24 minutes in the Da Vinci Xi group. However, researchers noted that this slight difference was not statistically significant (p > 0.05).

An 11-year Swedish registry study of 618 uterine sarcoma patients found that minimally invasive surgery yielded survival comparable to open surgery in early stages. However, adjuvant chemotherapy conferred no survival benefit in localized or advanced disease, highlighting stage and histology as key outcomes.
