Microsurgical treatment of varicocele: selecting most appropriate shunt.

Microsurgical drainage of spermatic veins tailored to the hemodynamic type of varicocele was performed in 20 patients. In 14 cases the procedure was indicated as prophylaxis and in 6 cases as treatment of infertility. Complete regression of varicosities was observed in 75 percent as early as six days postoperatively, in 85 percent at two weeks, and in 90 percent at twelve months. In the remaining 10 percent, a consistent reduction of varicocele was found. No patient experienced progression of the disease. Eighty-three percent of the patients with altered seminal parameters showed an improvement of them at a mean follow-up of 9.1 months.
