    Abstract:
    Autopsy was performed on 49 male cadavers and the entire course of the left testicular vein (LTV) was studied. The testicular venous pathway was divided into four levels: scrotal, inguinal, pelvic, and lumbar. At the scrotal level, many small testicular veins constituting the pampiniform plexus showed various anastomoses with the cremasteric and vasal veins. At the inguinal and pelvic level, 4-12 and 2-8 LTVs were recognized, respectively. At the pelvic level, absence of valves was seen in 33% of the cases. At the lumbar level, 1-5 LTVs were observed and were mainly anastomosed with the retroperitoneal, ureteral, and kidney capsular veins. Absence of valves at the lumbar level was seen in 37% of the cases. In 11 cases, the valves that were present were incompetent. The presence of more than one LTV at the lumbar level indicates the necessity for attentive identification of all of the testicular veins during surgical treatment of varicocele.
