Abstract: 【Abstract】〓Objective〓To investigate the totally extraperitoneal laparoscopic tension-free inguinal hernia repair (TEP) and its influence on testicular hemodynamics. Methods〓Sixty-six cases with unilateral inguinal hernia were enrolled in a prospective internally controlled cohort study, and were performed totally laparoscopic extraperitoneal tension-free inguinal hernia repair (TEP). Pre- and post-operative blood flow parameters of bilateral testicular arteries, including peak systolic velocity (PSV), end diastolic velocity (EDV), testicular volume and plasma testosterone level were studied and compared. Results〓In pre-operation of 48 hours, there were no statistical differences in PSV, EDV and testicular volume between the both side (all P values >0.05). In post-operation of 48 hours and two weeks after operation,PSV、EDV and testicular volume of the affected side were significantly lower than that of the other side (all P values <0.05). PSV, EDV and testicular volume were not significantly different in one month after operation. There were no statistically significant differences in plasma testosterone level in pre-operation of 48 hours, post-operation of 48 hours, 2 weeks after operation and one month after operation. Conclusion〓Testicular hypotension occurred in two weeks after TEP procedure on the affected side, and improved in 1 month later. Plasma testosterone level were not influenced.
