Experimental lymphangiography. Experience with direct medium injection into the parenchyma of the rat testis and prostate.

Direct injection of a new hyperemulsified radiopaque medium into the parenchyma of the testes produced rapid and excellent visualization of testicular lymphatic vessels and nodes. The technique is much simpler than previous methods. No ill effects on reproduction were demonstrated. Prostatic injections demonstrated the parenchyma well but no nodes or vessels were demonstrated.
