Retroperitoneal surgeries are often associated with post-operative ejaculatory dysfunctions. For successful nerve sparing surgery detailed knowledge of anatomy of lumbar splanchnic nerves (LSN) is mandatory. The present study was aimed to record number and positional variability of infrarenal lumbar splanchnic nerves so that iatrogenic injuries of lumbar splanchnic nerves could be avoided.

The study was conducted on 15 embalmed adult human cadavers. Lumbar part of sympathetic chain, corresponding splanchnic nerves were dissected from the level of left renal vein to pelvic inlet. Number and origin of the lumbar splanchnic nerves from the sympathetic trunk were noted.

Total 71 LSNs (nRIGHT= 35, nLEFT=36) were identified joining the cords of aortic plexus. Number of LSN joining the cord below the level of left renal vein varied from 2-4 cm. Second LSN was most consistently present and the 4th LSN was present in 4 cadavers only. Position of each LSN varied greatly. Centre of the superior hypogastric plexuses was shifted to the left of aortic bifurcation in 33 % cadavers and the average width of the plexus was 1.21cm.

Collective knowledge about LSN gathered from this study would help the surgeon in minimizing post operative complication related to ejaculatory dysfunction.The findings of the respected study will help the surgeons to improve and prevent certain retroperitoneal nerve sparing surgical procedures, which may help to preserve the lumbar splanchnic nerves during retroperitoneal surgeries and it may help to prevent iatrogenic injury which may lead to male ejaculatory dysfunction postoperatively in patients undergoing surgery. .
