To summarize surgical experiences with a new modified technique involving extraperitoneal single-incision robot-assisted laparoscopic radical prostatectomy based on Da Vinci SI system by reviewing case data, including follow ups, and to evaluate the safety and clinical efficacy of the surgical procedure. The case data from December 2020 to September 2022 of 321 patients undergoing modified single incision (without dedicated PORT) robotic-assisted laparoscopic radical prostatectomy via an extraperitoneal approach were reviewed. All procedures were performed by the same surgeon at our center. Perioperative data and postoperative urinary control, tumor control, and erectile function recovery were assessed. The immediate, 3-months, 6-months, 12-months, 18-months and 24-months complete urinary control rates were 34.3%, 56.6%, 79.7%, 85.7%, 89.6% and 90.7%, respectively; the 3-months, 6-months, 12-months, 18-months and 24-months biochemical recurrence rates were 3.4%, 5.2%, 9.1%, 21.7% and 30.2%, respectively; and for those with normal preoperative erectile function, the 3-months, 6-months, 12-months, 18-months and 24-months postoperative erectile function recovery rates were 52.2%, 60.0%, 70.7%, 72.2% and 73.9%, respectively. The new modified technique involving extraperitoneal single-incision robotic-assisted laparoscopic radical prostatectomy is safe and feasible. This technique has satisfactory surgical results, and this new method results in satisfactory urinary control, tumor control and recovery of erectile function. In addition, this new method is not limited to specific dedicated access devices, which facilitates its application.
