Clinical effect of internal spermatic vein high ligation with different operation methods on treatment of patients with varicocele

Objective To explore the effect of internal spermatic vein high ligation with different operation methods on treatment of patients with varicocele. Methods A total of 168 patients with primary varicocele were randomly divided into total spermatic cord ligation group( n = 56),testicular artery preservation group( n = 56) and venous ligation group( n = 56). The semen quality,short and long term complications,fertility,recurrence and FSH before operation and 6 months after operation were compared among three groups. Results After operation,the sperm density,sperm motility,sperm deformity and FSH concentrations significantly improved in all the groups( P0. 05),and of the three groups,the degree of improvement was the greatest in the venous ligation group,while was the worst in the total spermatic cord ligation group( P0. 05). The incidence rate of postoperative secondary hydrocele in the venous ligation group was significantly lower than that in the other two groups( P0. 05). The incidence rate of testicular atrophy in the total spermatic cord ligation group was significantly higher than that in the other two groups( P0. 05). The pregnancy rate of the vein ligation group was significantly higher than that of the other two groups( P0. 05). Conclusion Application of surgical method of ligating internal spermatic vein only and preserving testicular artery and spermatic lymph pipeline can effectively improve sperm quality of patients with varicocele,reduce postoperative complications and improve pregnancy rate of spouse.
