Abstract

Background: To comprehensively evaluate the efficacy and safety of Retzius sparing (RS) for men undergoing robot-assisted laparoscopic prostatectomy (RARP). Methods: We searched four electronic databases and reference lists of relevant studies for eligible research published before March 11, 2019. After quality assessment, eligible studies were synthesized for relevant outcomes, including positive surgical margin (PSM), continence, incontinence, complication, console time, and hospital stay. Results: Two randomized clinical trials and four observational studies were included in this study. Quantitative syntheses revealed significantly higher PSM rates in RS-RARP compared with conventional RARP (c-RARP) (odds ratio [OR] 1.68, p = 0.02). Furthermore, we found significantly higher PSM rates at the anterior site in RS-RARP compared with c-RARP (OR 4.34, p = 0.03) and significantly lower incontinence rates in RS-RARP in the first month (OR 0.30, p < 0.001) and 12th month (OR 0.25, p < 0.001). Conclusions: Our syntheses revealed higher PSM rates in the RS-RARP group, especially in the anterior aspect. However, RS-RARP had superior functional outcome of urinary continence and lower console time than did c-RARP with equivalent complication rates. Thus, we suggest that operators pay more attention to making clear surgical margins if the lesion is in anterior prostate when performing RS-RARP.
