We dissected 10 cadavers after bilateral SNM lead implantation (<jats:italic>n<\/jats:italic>\u2009=\u200920), using two different standardized implantation techniques. The cadavers were categorized as group A (<jats:italic>n<\/jats:italic>\u2009=\u200910), representing the conventional guided implantation group and group B (<jats:italic>n<\/jats:italic>\u2009=\u200910), where SNM implantation was conducted with the novel fluoroscopy-guided \u201cH\u201d-technique.
