[Intracavernous injection of papaverine. Diagnostic value].

The authors use the intracavernous injection of papaverine (ICP) as a diagnostic test in order to differentiate between organic and psychogenic erectile impotence. Comparison of the results of this test with those of nocturnal penile plethysmography and Doppler studies of the penile vessels demonstrated a good correlation. However, the ICP test cannot be used alone to confirm the organic or psychogenic nature of erectile impotence.
