Objective To analyze the impact of the interval time(IT)between prostate biopsy(PB)and radical prostatectomy(RP)on the perioperative safety and prognostic efficacy of prostate cancer patients.Methods A retrospective analysis was performed on 87 patients who underwent extraperitoneal laparoscopic RP at our hospitals during Jun.2022 to Nov.2024.The patients were divided into the IT ≤2 weeks group(n=42)and the IT ≥4 weeks group(n=45)according to the interval between PB and RP.Baseline data,perioperative indicators,postoperative inflammatory factors,postoperative pathological results,urinary continence,and complication rates were compared between the two groups.Results No statistically significant differences were observed between the two groups in baseline information,operation time,intraoperative blood loss,intraoperative transfusion rate,postoperative hospital stay,catheter removal time,inflammatory factors and complications(P＞0.05).Pathological results showed no significant differences in cancer tissue proportion,positive rate of lymph node,positive rate of surgical margins,and postoperative Gleason scores(P＞0.05).However,the IT ≤2 weeks group exhibited significantly fewer cases of perineural invasion(25 vs.36,59.52％vs.80.00％)and vascular invasion(5 vs.12,11.90％vs.26.67％)compared to the IT≥4 weeks group(P＜0.05).There were no significant differences in postoperative urinary control rate and prostate-specific antigen(PSA)level between the two groups(P＞0.05).Conclusion Radical prostatectomy performed ≤2 weeks after prostate biopsy demonstrates better safety and prognosis.

Magnetic anchoring technology provides a new development opportunity for current minimally invasive surgery. The magnetic anchoring abdominal video system based on this technology can effectively improve the operability and minimally invasiveness of single-port laparoscopic surgery. The development history of magnetically anchored abdominal video system was reviewed, and the design features and deficiencies of various types of magnetically anchored video devices were compared and analyzed. The evolution characteristics of the magnetic anchored video system are explained from minimally invasive and intelligent perspectives, and the challenges and opportunities of magnetic anchored video system are summarized and prospected.
