Comparison of outcomes in laparoscopic radical prostatectomy and open radical prostatectomy / 中华泌尿外科杂志

ABSTRACT

Objective To compare outcomes of laparoscopic radical prostatectomy (LRP) and open radical prostatectomy (ORP) performed in our hospital.Methods A non-randomized,retrospective comparative study was performed to analysis 302 prostate cancer patients from January 2011 to June 2014.One hundred and ten patients underwent LRP and 192 underwent ORP.There were no significant differences between the LRP and ORP groups with respect to patient age,body mass index,PSA level,Gleason Score,clinical T stage and transrectal ultrasonography prostate volume (P ＞ 0.05).The operating time,estimated blood loss,catheter retaining time,hospital stay time,positive surgical margin rate and urinary control rate were compared between the 2 groups.Results The median operative time of the ORP group and the LRP group was 95 min and 120 min,the difference between groups was significant (P ＜ 0.01).The median duration of hospitalization of the 2 groups was 9 d and 6 d,the difference between groups was significant (P＜0.01).ORP group and LRP group's estimated blood loss was 350 ml and 250 ml.Days of tube drainage were 3 d in both groups.Days of urinary catheterization drainage after surgery were 16 d and 15 d,respectively.Positive margin rate was 10.4％ and 12.7％.Urinary continence recovery rates at 3 month were 80.2％ and 70.8％.Urinary continence recovery rates at 6 month were 85.9％ and 87.3％.No significant difference was observed in the above index (P ＞ 0.05).Conclusions Compared with ORP,LRP has shorter hospital stay time and longer operating time.Both LRP and ORP have good outcomes in oncological control and function rehabilitation.Both of them are important procedures to treat localized prostate cancer.
