Laparoscopic radical prostatectomy compared to open radical prostatectomy: Comparison between surgical time, complications and length of hospital stay

Abstract Introduction There are very few articles comparing open radical prostatectomy (OPR) with laparoscopic radical prostatectomy (LRP). Objetives To compare the surgical time, the postoperative complications and the hospital stay in patients with localized prostate cancer treated with ORP or LRP. Materials and methods Comparison between two patients cohorts (312 with ORP and with 206 LRP) between 2007-2015. Postoperative complications were collected as defined in to the EAU Guidelines recommendations and they were classified according to the Clavien-Dindo classification. To compare the qualitative variables, we employed the chi-squared test and ANOVA for quantitative variables. We performed a multivariate analysis using logistic regression with dependent qualitative variables and a lineal regression with dependent continuous variables. Results The mean duration of ORP was 3:05 h and 4:35 h for LRP (p = 0,0001). The 26.4 % of the patients presented any postoperative complication. 31.2 % of ORP and 19.3 % of LRP (p = 0,003). The mean of hospital stay was 4 days. In ORP group was 4 days in contrast to LRP with 3 days (p = 0,008). The LRP (p = 0,0001), lymphadenectomy (p = 0,02) and nerve-sparing (p = 0,01) were independent predictor factors of extension of surgical time. LRP was a protector independent factor of complications (OR = 0,48 p = 0,007). The type of prostatectomy didn’t influence in the length of hospital stay. Conclusions LRP showed higher surgical time, less complications and it didn’t influence the hospital stay.
