Introduction. Principle of the combined analysis of the operation outcomes is more informative than discrete analysis of the single components. For radical prostatectomy three parameters (trifecta) could be under considerations – oncological outcome, continence and sexual function «trifecta», as well as more complex «pentafecta» with addition of postoperative complications and surgical margin status.

Results. Two groups of sexually active men with confirmed localized prostate cancer (PCа) were stratified according to the operation type – radical retropubic prostataectomy (RRPE) in 33 patients and robot-assistet radical prostataectomy (RARP) in 62 patients. Trifecta and pentafecta statuses were assessed at 12 months after operation. In RRPE group trifecta was achieved in 21.2% of patients, in RARP group – in 66.1%. Pentafecta was achieved in 6.1% of open operation and in 43.5% of robotic-assisted surgeries.

Conclusions.The number of patients, which were corresponding to the criteria of achievement of trifecta and pentafecta, was more in the group with RARP, than in the RRPE group, which could be considered as the ground for recommendation of RARP as new treatment standard for clinically localized PCа.
