Percutaneous sclerotherapy of varicocele.

The results of selective phlebography of the spermatic vein are reported in 580 infertile men with abnormal sperm morphology and suspected varicoceles. Percutaneous transvenous retrograde sclerotherapy of the internal spermatic vein was performed in 260 of the patients. Follow-up phlebography in 109 patients 3 to 6 months after treatment revealed a persistent varicocele in only 3% of them.
