Outcomes of retropubic, laparoscopic, and robotic-assisted prostatectomy
Abstract
OBJECTIVES: To compare outcomes of radical retropubic, laparoscopic, and robotic-assisted prostatectomy using evidence-based analysis.
METHODS: We performed meta-analysis of observational studies directly comparing radical retropubic, laparoscopic, and robotic-assisted prostatectomy for the treatment of localized prostate cancer. The primary outcomes were operative blood loss, perioperative transfusion, surgical margin status, postoperative urinary incontinence, and postoperative erectile dysfunction. Based on established similarities in surgical principles, we combined laparoscopic and robotic-assisted data into a single group. We estimated standardized mean differences (SMD), risk ratios (RR), and risk differences (RD) using random effects models.
RESULTS: Nineteen studies (n = 3893 patients) met inclusion criteria for this analysis. Compared with those undergoing retropubic prostatectomy, patients undergoing laparoscopic or robotic-assisted prostatectomy experienced less operative blood loss (SMD -1.74, 95% confidence interval [CI] -1.74 to -1.49, P <0.001) and were 77% less likely to receive a perioperative transfusion (RR 0.23, 95% CI 0.11 to 0.49, P <0.001). There was no significant difference in overall risk of positive surgical margin (RR 0.88, 95% CI 0.74 to 1.06, P = 0.17). There were also no significant differences in 1-year urinary continence (P = 0.49) and 1-year erectile function (P = 0.09); however, these outcomes were measured using nonvalidated instruments.…
