Ureteric Nerve, Anterior View

Description

Running along the retroperitoneal course of the male ureter, the ureteric nerve is traced as a slender autonomic filament descending from the lumbar sympathetic chain and periarterial plexuses to join the ureteric plexus. Proximally it lies near the psoas major and lumbar vertebral bodies, then tracks inferiorly toward the pelvic brim where the ureter crosses anterior to the bifurcation of the common iliac artery. Medially, fibers blend with the superior hypogastric plexus and continue into the inferior hypogastric (pelvic) plexus, maintaining a close longitudinal relationship to the ureter as it approaches the posterolateral bladder wall. Small, segmental branches appear to wrap toward the ureteral muscularis. Fine anatomy, easily missed. This relationship matters when you teach or operate in the retroperitoneum, because ureteric innervation travels with the same connective tissue planes that surgeons and endoscopists mobilize during ureterolysis, pelvic lymph node dissection, and anterior approaches to the lumbosacral spine. Visceral afferents from the ureter run back through T11 to L2 sympathetic pathways, explaining classic “loin-to-groin” referral in ureterolithiasis and why colic can localize as a stone migrates from the upper ureter to the distal segment near the ureterovesical junction. Pelvic autonomic disruption can also contribute to postoperative dysmotility of the ureter. Use this plate in gross anatomy, neuroanatomy, or urology teaching to connect the lumbar and sacral plexuses to autonomic pelvic networks, and in surgical atlases covering retroperitoneal exposure, ureteral identification, and complication avoidance in male pelvic procedures. It also supports radiology and pain-medicine texts that map ureteral pain referral and autonomic pathways. Anatomical accuracy verified by SciePro's Medical Advisory Board.
