Urinary Continence Function After Robot-Assisted Vs. Pure Laparoscopic Radical Prostatectomy: A Systematic Review

Objective To systematically review the urinary continence function after Robot-Assisted vs. Pure Laparoscopic Radical Prostatectomy.Methods Databases as PubMed, The Cochrane Library, Web of Science, CNKI, VIP, and WanFang Data were searched for controlled studies comparing robotic-assisted laparoscopic prostatectomy (RALP) with pure laparoscopic radical prostatectomy (LRP) for local prostate cancer. Inclusion and exclusion criteria, extracted data and assessed the methodological quality according to the Gochrane methods handbook. Then, data was performed by RevMan 5.2 software.Results Two randomized controlled trials and seven non-randomized controlled trials were included in this analysis. A total of 1950 patients were involved:1095 cases of RALP and852 cases of LRP. The outcomes showed that, the urinary continence rate after operation, there was significant differences between RALP and LRP at one month (OR=2.28), three months (OR=1.21), six months (OR=1.97) and twelve months (OR=1.53, P<0.05).Conclusion For the treatment of localized prostate cancer, RALP has better recurrence of urinal function after operation.
