Clinical Application Of Robot Assisted Laparoscopy In The Treatment Of Localized Prostate Cancer

Objective:By comparing and analyzing the difference of curative effect between robotic laparoscopic radical prostatic cancer(RALP)and traditional laparoscopic radical prostatic cancer(LRP)in the treatment of localized prostate cancer,the advantages and disadvantages of the two surgical methods were further discussed,so as to provide a new choice for the clinical treatment of prostate cancer.Methods:Collected urology department of China-Japan Union Hospital of Jilin University and Jilin Cancer Hospital from March 2018 to November 2020.Postoperative pathology confirmed prostate cancer.According to the inclusion and exclusion criteria,40 patients were included in this study and were divided into two groups according to different surgical methods: 20 patients in the RALP group and 20 patients in the LRP group.The efficacy and safety of the two treatment methods were analyzed by comparing the differences of operation time,intraoperative blood loss,bladder neck-urethral anastomosis time,drainage tube removal time,indwelling catheter time,postoperative hospital stay and urine leakage rate between the two groups.Results:The mean age of patients in the LRP group was 64±6.58 years old,and the mean age of patients in the RALP group was 66±8.35 years old.The mean prostate volume was 52±10.97cm~3 in the LRP group and58±10.46cm~3 in the RALP group.Mean body weight was 67.35±7.08 kg in the LRP group and 67.30±9.21 kg in the RALP group.There was no statistically significant difference between the two groups(P > 0.05).The operation was completed successfully in both groups,and no serious complications occurred.Compared with intraoperative and postoperative observation indexes in the LRP group,intraoperative blood loss,bladder neck-urethral anastomosis time,drainage tube indwaining days,urinary tube indwaining time,postoperative time out of bed and length of hospital stay in the RALP group were less,with statistical significance(P <0.05).The positive rate of surgical margin between the two groups was P > 0.05,and the difference was not statistically significant.Normal urinary control: the number of urinary pads used daily ≤1;In the LRP group,17 of the 20 patients had normal urine control rate(85%).One case of 20 patients in the RALP group had abnormal urine control,and the urine control rate was 95%(P value 0.605,> 0.05).The difference was not statistically significant.Conclusion:Compared with the two surgical methods,there was no significant difference in the rate of urine leakage and the positive rate of surgical margin between the two methods.RALP technology can shorten the operation time,reduce the amount of intraoperative blood loss,speed up the recovery of patients,shorten the length of hospital stay,and ensure the surgical effect,which has certain advantages and is worth popularizing.
