Clinical experience with the radioisotope varicocele scan as a screening method for the detection of subclinical varicoceles.
The association of varicoceles and subfertility has been well documented. Although varicoceles remain the most common surgically correctable cause of male infertility the diagnosis of small varicoceles remains a challenge. We evaluated 40 men with an isotope blood pooling scan. Seven volunteers served as either positive or negative controls. Complete correlation between physical findings and the isotope scan was found. The 6 patients with obvious clinical varicoceles and a stress pattern on semen analysis all had positive scans. The 18 patients with a stress pattern and who were clinically suspected of having a varicocele all had positive scans. Of 9 patients evaluated for infertility with a stress pattern but no clinical evidence of varicocele 6 had positive scans. We believe that the isotope scan will prove to be a useful procedure in the detection of nonpalpable varicoceles in selected subfertile men.
