AB  - Aim: We analyzed pentafecta outcomes [complication-free, continence, potency, negative surgical margins (NSM)], biochemical recurrence (BCR)-free] of 230 patients undergoing robotic-assisted radical prostatectomy (RARP) with bilateral neurovascular (NVB) preservation. Patients and Methods: Patient outcomes (group I, cases 1-115; group II, cases 116-230) were assessed prospectively. Definitions were: continence, using no pads; potency, ability to achieve/maintain erections firm enough for sexual intercourse; positive surgical margin, presence of tumor tissue on inked specimen surface; and BCR, two consecutive PSA levels >0.2 ng/ml after RALP. Results: The mean patient age was 62.5 years, mean PSA=8.62 ng/ml. The complication-free rate was 93.9% (216/230), continence rate 98.3% (226/230), potency 86.1% (198/230), NSM 77.0% (177/230) and BCR-free 92.6% (213/230). The trifecta rate (continence, potency, BCR-free) was 81.7% (188/230). The pentafecta rate was 60.4% (139/230). Conclusion: Pentafecta is the new standard of outcomes for RARP with bilateral NVB, with patient selection and reduced positive surgical margins attaining best outcomes.
