Comparison of Perioperative Outcomes Between da Vinci XI and da Vinci SI/SP Robotic Radical Prostatectomies: A Meta-Analysis of Comparative Studies.

BACKGROUND

This study aimed to compare perioperative outcomes between da Vinci XI and da Vinci SI or SP robotic radical prostatectomies.

METHODS

The study systematically searched four databases: Embase, PubMed, Cochrane Library, and Web of Science. The search time ranged from database creation to July 2025. Statistical analysis was performed using Stata17. Effect denoted a continuous variable, whereas OR/RR denoted a binary variable, and the 95 % confidence interval (CI) was calculated.

RESULTS

The seven included studies involved 2297 patients undergoing robotic radical prostatectomy. Compared with SP, XI had a longer hospital stay (effect, 0.91; 95 % CI 0.04-1.77; P < 0.05). Compared with SI, XI had a lower positive margin rate (odds ratio, 0.74; 95 % CI 0.57-0.97; P < 0.05). Operation time, estimated blood loss, overall complications, and major complications did not differ among XI, SI, and SP.

CONCLUSION

Compared with SP, XI's hospital stay appeared to be longer. Compared with SI, XI seemed to have a lower positive surgical margin. However, more research is needed to determine differences in oncology outcomes and cost-effectiveness among several robotic surgical platforms.
