Abstract

Abstract:

Objective

To explore the safety and efficacy of domestic Jinfeng single-port robot-assisted radical prostatectomy (SP-RARP) in the treatment of patients with intermediate-high risk prostate cancer (PCa).

Methods

The clinical data of patients who underwent Jinfeng SP-RARP in the First Affiliated Hospital of Anhui Medical University from March 2025 to September 2025 were collected, and the intraoperative and postoperative conditions of patients were analyzed.

Results

A total of 53 patients were included in this study. The median age was 68.4 (55.0, 82.0) years, the median body mass index (BMI) was 23.48 (16.76, 32.14) kg/m², the median prostate-specific antigen (PSA) level was 11.82 (2.00, 52.70) ng/mL, and the median prostate volume was 32.83 (12.38, 96.59) mL, among them, there were 42 patients with intermediate-risk prostate cancer and 11 patients with high-risk prostate cancer. All surgeries were performed successfully without changing the surgical approach during the operation. The median operation time was 135 ( 82, 230) min, and the median blood loss was 48 (10, 530) mL. No intraoperative blood transfusion was required for any patient. The median postoperative hospital stay was 4.1 (3.0, 9.0) days. No severe complications (Clavien grade ≥Ⅲ) occurred during or after the operation. Positive surgical margins were observed in 15 patients (28.30%). The urinary continence rate was 77.35% (41/53) at the 1-month postoperative follow-up and 81.13% (43/53) at the 3-month postoperative follow-up.

Conclusion

The domestic Jinfeng single-port robot can be safely used for the treatment of intermediate-high risk PCa with good efficacy, and this surgical method has advantages such as minimal trauma and rapid recovery.
