outcome were excluded. When there was no mention about any sparing of the neurovascular bundles
(NVBs), the procedure was taken a non-nerve-sparing procedure and thus also excluded along with the
procedures performed without robotic assistance. A total number of 25 relevant publications were selected
investigating male NS RARC, assessing functional outcomes with respect to potency and urinary continence
along with other surgical standard indicators.
