“…The aim of this is to preserve bilateral lumbar splanchnic nerves and the superior hypogastric plexus. In these patients, ejaculatory function has been reported to be preserved in more than 90%, and tumor recurrence occurred in up to 12% 8,9 …”

“…Stimulation of the pelvic nerve causes no detectable motor response in the seminal tract in many mammals. On the pathway proximal to the HGN, stimulation of the superior hypogastric plexus or the LSN causes emission and bladder neck contraction in humans, 7 whereas removal of the intermesenteric plexus has no effect on ejaculation 8,9 …”

“…On the pathway proximal to the HGN, stimulation of the superior hypogastric plexus or the LSN causes emission and bladder neck contraction in humans, 7 whereas removal of the intermesenteric plexus has no effect on ejaculation. 8,9 In animals, the levels of the LSNs demonstrating motor activity of the vas deferens is second to fifth, mostly the second and third. 2 The same levels of the LSNs also provide excitatory input to the prostate and bladder neck.…”

“…In these patients, ejaculatory function has been reported to be preserved in more than 90%, and tumor recurrence occurred in up to 12%. 8,9 The modified RPLND technique aims to preserve unilateral LSNs and the superior hypogastric plexus, without identifying the nerves. The dissection is performed bilaterally or ipsilaterally 5 above the inferior mesenteric artery and ipsilaterally below the artery.…”

“…However, results of operations and animal experiments contradicted this theory. Section of the intermesenteric plexus, which interrupts communication between the major splanchnic nerve and the hypogastric nerve, caused no disturbance of ejaculatory function in humans (Kihara et al, 1988;Sherlag et al, 1989). Further, stimulation of the intermesenteric plexus elicited no observable vasal responses in animals (Kihara et al, 1992a;Kihara and deGroat, 1997a).…”

Background: The laterality of the signals passing through the splanchnic nerves to the vas deferens has not been well studied. Methods: The present study was designed to determine the bilateral distribution of sympathetic nerves to the rat vasa deferentia by measuring intravasal pressure (VP) responses to electrical stimulation of left lumbar splanchnic nerves (LSN) following consecutive transections of more distal nerves. Results: L2‐L6 LSN stimulation increased VP bilaterally. Left VP responses decreased slightly (<20%) after section of the right hypogastric nerve (HGN) and then were abolished by subsequent section of branches (B‐M‐APG) between the left major pelvic (MPG) and accessory pelvic ganglia (APG). Left VP responses were decreased by >80% after section of left HGN, not changed further by subsequent section of commissural branches (CB‐MPG) between the MPG, and completely eliminated by section of commissural branches between the APG (CB‐APG). Right VP responses were decreased slightly (<20%) by section of the left HGN and then abolished by section of the right B‐M‐APG. These responses were also decreased by >70% by section of right HGN, not changed by section of CB‐MPG, but then completely eliminated by section of CB‐APG. Conclusions: These results indicate that the left lumbar sympathetic pathway to the vas deferens is distributed bilaterally and exhibits two crossing points at the level of the inferior mesenteric ganglion and APG.
