Methods A total of 372 consecutive patients underwent RARAP using the da Vinci Si® robotic surgical system .Group I (n = 210) included patients undergoing pf-ssRARP and Group II (n = 162) included patients undergoing MPRARP.Demographics and perioperative data including postoperative recovery outcomes were recorded and compared between the two groups. Results Overall mean operative time was significantly shorter with the pf-ssRARP compared to the MPRARP ( p < 0.05).The length of hospitalization after the pf-ssRARP was shorter( p < 0.05).In Group I, the positive surgical margin rate was 15.2%, while in Group II, the positive margin rate was 33.3% ( p < 0.05).The rate of instant urinary continence was significantly higher in Group I than in Group II( p < 0.05).The percentage of urinary continence was higher in the pf-ssRARP than in the MPRARP,at 6 months post-surgery ( p < 0.05) and 9 months post-surgery ( p 0.05).The two groups were comparable in terms of total hospitalization costs( p < 0.05). Conclusion The Improved (port-free) single-site robot-assisted laparoscopic radical prostatectomy is a practical and easy technique to implement in clinical practice. robot-assisted radical prostatectomy improved technology prostate cancer extraperitoneal implementation Full Text Additional Declarations No competing interests reported.
