MP62-07 PREDICTORS OF READMISSION FOLLOWING OPEN AND MINIMALLY INVASIVE RADICAL PROSTATECTOMY USING THE NATIONAL SURGICAL QUALITY IMPROVEMENT PROGRAM (NSQIP) DATABASE

methods are not equivalent (with a pre-specified tolerance limit margin of 0.5 cm for equivalencewith a common SD of 0.8 cm). TheMann-Whitney and Chi square tests were used for statistical analysis RESULTS: 121 patients have been randomized. 1 patient from the LS group and 1 from AS group were lost to f-up, 1 patient in the LS group was converted so finally we evaluated 58 pts in the LS arm and 60 in the AS arm. The median follow-up was 32,53 months (range 16e56 months). Operating time was longer for LS (mean 121 min for AS vs 219 min for LS, p<0.001). Intra-operative blood loss was higher in AS (mean 245 ml for AS vs 99,13 ml for LS, p<0.001) and hospital stays were longer (mean 5.8 days for AS vs 4.4 days for LS, p<0.001). The complications according to the Clavien-Dindo classification were 14 in the AS arm and 13 in the LS arm for the grade I (p1⁄4 0,15), 11 in the AS group Vs 1 in the LS group for the grade II (p1⁄40,02) and 1 in the AS group Vs 4 in the LS group for the grade III (p1⁄40,017). Tab I shows the mean postoperative point C/D evaluation for both techniques. No apical prolapse in both groups recurred, asymptomatic stage IeII recurrence was reported in 10% in AS vs 24.1% in LS (p1⁄40.051) CONCLUSIONS: These data show LS provide outcomes as good as AS with decreased morbidity, less blood loss and shorter recovery times. Recurrency in anterior and posterior compartment POP showed a difference in the two groups which, although not statistically significant, need to be evaluated in the long-term
