研究目的:

主要目的 比较康多机器人单孔与多孔经腹膜外入路前列腺癌根治术在肿瘤早期控制效果方面的差异,以术后切缘阳性率为主要终点,验证单孔术式的非劣效性。 次要目的 系统评估两种术式在以下方面的优劣: 围手术期安全性:手术时间、术中出血量、术后90天并发症发生率; 术后恢复:引流管留置时间、住院天数、术后出院时疼痛评分; 中期功能预后:术后3、6个月的尿控恢复率、性功能恢复率; 肿瘤学预后:术后6周PSA达标率、术后1年无生化复发率。  

Objectives of Study:

Primary Objective:To compare early oncological control between Kangduo robot-assisted single-port extraperitoneal radical prostatectomy and multi-port extraperitoneal radical prostatectomy, using the positive surgical margin rate as the primary endpoint, and to evaluate the non-inferiority of the single-port approach.Secondary Objectives:To systematically compare the two surgical approaches in the following aspects:Perioperative safety: operative time, intraoperative blood loss, and 90-day postoperative complication rate.Postoperative recovery: duration of drain placement, length of hospital stay, and pain score at discharge.Mid-term functional outcomes: urinary continence recovery rate and sexual function recovery rate at 3 and 6 months postoperatively.Oncological outcomes: rate of achieving PSA ≤ 0.2 ng/mL at 6 weeks postoperatively, and 1-year biochemical recurrence-free rate.

Exclusion criteria:

1. Previous treatment related to prostate cancer, including but not limited to: local prostate ablation therapy, radiotherapy, etc. (except neoadjuvant endocrine therapy, which should be recorded and used as a stratification/analysis factor). 2. Previous history of transperitoneal prostate surgery, major pelvic surgery or radiotherapy is expected to seriously affect the anatomy of extraperitoneal space or increase the difficulty of surgery. 3, Imaging examination (such as MRI, bone scan, CT, etc.) suggested the presence of pelvic lymph node metastasis (N1) or distant metastasis (M1). 4. The presence of severe heart, lung, liver, kidney dysfunction or coagulopathy, which was evaluated by anesthesiology and urology, was contraindicated for robotic surgery and general anesthesia. 5, have any uncontrolled acute or chronic active infection. 6. Patients with a history of other malignant tumors and signs of activity in the past 5 years and stable tumor control could be enrolled. 7. Known or suspected history of psychiatric disorders, cognitive impairment, or alcohol/drug abuse, poor compliance, and inability to cooperate with the treatment and follow-up required by the study protocol. 8. Any other reasons for eligibility in the trial as judged by the investigator
