Study on the the effect of testicular artery ligation or not in laparoscopic high ligation of spermatic vein on testicular

Objective To discuss the effect of testicular artery ligation or not in laparoscopic high ligation of spermatic vein on testicular.Methods Twenty patients treated by spermatic vein and testicular artery cluster ligation in laparoscopic high ligation of spermatic vein were selected as observation group in this study,20 patients with simple ligation of the inside spermatic vein treated by clinical application of laparoscopic were selected as control group,they were followed up after operation of six months,a year and two years,testicular blood supply (according to the index of measuring the testicular artery blood flow velocity),testicular size and raw spermatogenic function changes of two groups in the preoperative and postoperative were compared and analyzed,and the incidence of complications were observed.Results The postoperative clinical observation for two years,the values of testicular artery blood flow velocity and observation group was similar compared with before operation,there was no significant difference between before and after surgery (P 0.05).Testicular volume of observation group had no narrowing (P 0.05).In addition,the semen quality of two groups were significantly improved after surgical treatment,there was one patient with a small amount of effusion in the tunica vaginalis were found in observation group in the follow-up,and control group had no complications,there was no significant difference between two groups (P 0.05).Conclusion Spermatic vein and testicular artery cluster ligation in laparoscopic high ligation of spermatic vein has no significant impact to the testicular artery ligation cluster arterial blood supply to the testis and the spermatogenic function without testicular atrophy.So the operation is safe and feasible.
