Brief summary
This study is a two-arm, multicenter, randomized controlled clinical trial on whether single-port extraperitoneal VIP RARP is non-inferior to multi-port transperitoneal RARP in terms of functional recovery rate and other key metrics.
Detailed description
Multicenter enrollment of 480 patients with localized prostate cancer meeting enrollment criteria are randomized to undergo either single-port robotic extraperitoneal VIP radical prostatectomy or multi-port robotic transperitoneal bilateral intrafascial radical prostatectomy for perioperative data recording, treatment, and monitoring with 1 year follow up.
Interventions
Patients with localized prostate cancer are randomized into this group in a 1:1 ratio and receive single-port extraperitoneal robotic-assisted radical prostatectomy with Vattikuti Institute Prostatectomy(VIP) techniques. The investigators will monitor patients for perioperative data recording, treatment and 1-year follow-up.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Potency recovery rate | 3 months after surgery | Potency recovery rate 3 months postoperatively, based on the patient's description of whether the erection is firm enough for sexual activity or intercourse. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Continence recovery rate | Up to 1 year, at a frequency of 1, 3, 6, and 12 months postoperatively | The rate of recovery of continence postoperatively, measured in the number of pads used per day. |
| PSA | Up to 1 year, at a frequency of 1, 3, 6, and 12 months postoperatively | PSA status postoperatively,measured in ng/mL |
| Potency recovery rate | Up to 1 year, at a frequency of 1, 6, and 12 months postoperatively | Potency recovery rate will be assessed by patient's self-reported erectile firmness for sexual activity or intercourse, International Index of Erectile Dysfunction(IIEF-5) score(from 0-25 score, a higher score means a worse outcome), and phosphodiesterase5 (PDE-5)inhibitor intake frequency according to patients' despciption (a higher intake means a worse outcome). |
| Clavien-Dindo complication score | Every day during period of hospitalization (up to 7 days) | Clavien-Dindo complication score measured in the following grades(a higher grade means a worse outcome) : First grade:complications that do not require medication, surgery or endoscopic treatment. Second grade: complications require to be treated with drugs, including blood transfusion and parenteral nutrition. Third grade: complications that require surgery, endoscopy, or radiation therapy. Fourth grade: the emergence of life-threatening complications, including cerebral hemorrhage, etc., which is also divided into 4a and 4b, 4a is single-organ dysfunction, 4b is mainly multi-organ dysfunction and injury. Fifth grade: death. |
| Operative time | During operation(on an average of 90-120minutes ) | Time elapsed from skin incision to placement of the final skin suture, measured in minutes |
| Estimated blood loss | During operation(on an average of 90-120minutes ) | Estimated blood loss, measured in volume (mL) |
| Number of additional ports | During operation(on an average of 90-120minutes ) | Number of additional ports needed in surgery |
| Period of hospitalization | During period of hospitalization (up to 7 days) | Hospital stay, counted in days from the first day of hospitalization to discharge |
| Period of hospitalization post surgery | Post surgery, during period of hospitalization (up to 7 days) | Hospital stay, counted in days from the time of transfer to the post anesthesia care unit (PACU) to discharge |
