Intraoperative spermatic venography during varicocele surgery in adolescents.
Intraoperative internal spermatic venography performed immediately following varicocele ligation in the adolescent has been touted as reducing varicocele persistence rates. Previously published data corroborate this statement with low persistence rates. Other series in which venography was not performed report a failure rate of 9 to 30%. During a 5-year period a total of 64 varicocele ligations was performed in 62 male adolescents at our institution. Followup postoperatively revealed an overall varicocele persistence rate of 9%. All patients had intraoperative internal spermatic venography on the affected side. Of 64 venograms 16% had shown collateral drainage that, if not ligated, may have resulted in varicocele persistence. These cases accounted for only 1 of the persistent varicoceles. Additionally, venograms had demonstrated filling of the ipsilateral external iliac vein in 8% of the cases. Despite the fact that no attempt was made to ligate these collaterals, none of these patients had a persistent varicocele. After varicocele ligation 30 of 62 patients were followed long enough to evaluate for testicular catch up growth. Of these 30 patients 24 demonstrated an average relative increase in left testicular volume of 17%. These data support routine intraoperative internal spermatic venography while performing varicocele ligation in the adolescent.
