经尿道前列腺切除术后机器人前列腺癌根治术的临床应用OA

Objective:To summarize the clinical experience of robot-assisted radical prostatectomy(RARP)after transurethral partial prostatectomy.Methods:The clinical data of 30 patients admitted from Sep.2021 to Feb.2025 were collected.All patients were diagnosed with prostate cancer after transurethral partial prostatectomy(transurethral resection of the prostate or transurethral enuclea-tion of the prostate)and then underwent RARP again.Before RARP,10 patients had undergone transurethral resection of the prostate,and 20 patients had undergone transurethral enucleation of the prostate.The interval between transurethral resection/enucleation and RARP ranged from 3 months to 2 years.All operations were performed via the extraperitoneal approach.Results:All 30 patients successfully completed the operation.The pathological reports of 24 patients indicated tumor residue or foamy cell changes,and 6 patients indicated benign prostatic hyperplasia complicated with prostatitis.Pathological examination of one patient indicated positive resection margin.The total prostate-specific antigen of all patients was reexamined 6 weeks after operation,and all decreased to below 0.02 ng/mL.Recovery of urinary control:1 week after urinary catheter removal,5 patients regained urinary control;1 month after opera-tion,10 patients regained urinary control;3 months after operation,25 patients regained urinary control.Urethral stricture occurred in 6 patients after operation,and urination returned to normal after 4 to 6 times of transurethral dilation.Conclusions:RARP after transure-thral partial prostatectomy has particularities.Adequate preoperative evaluation of the periprostatic conditions of patients,meticulous intr-aoperative operation,and strengthened postoperative management are required to ensure the safety and effectiveness of the operation.
