High-resolution real-time sonography of scrotal varicocele.

Real-time sonography of the scrotal veins was performed in 13 subjects with clinically obvious or small varicocele and in 10 normal controls. In normals, the vessels were 0.5-1.

Comparison of computed tomography with high-resolution real-time ultrasound in the localization of the impalpable undescended testis.

Localization of an undescended testis was attempted in 23 instances in 20 patients using both computed tomography (CT) and high-resolution real-time ultrasonography. The testis was identified and correctly localized 16 times by CT and 15 times by ultrasound. There was one false-negative diagnosis by CT and two by ultrasound.

The diagnosis and surgical management of vasculogenic impotence.

Thirty-two patients have been treated for organic impotence at our institution during a 16-month period. Of these patients 5 were found to have penile vascular insufficiency and underwent a femorocavernosal bypass with an autogenous saphenous vein graft. Initial results were excellent but late failures occurred.
