Significance of cavernosography in standardized cavernosometry.

Ninety-five patients with erectile dysfunction underwent standardized cavernosometry and cavernosography. In a first stage, the investigation was performed in each patient without and in a second stage with 60 mg papaverine injected intracavernously. A pathological maintenance flow rate between 20 and 120 ml/min decreased by 55% on average. The induction flow is of considerable variability and of poor diagnostic value. For quantification of venous leakage, the maintenance flow rate is of great importance and in correlation with the time of pressure decrease. Our results with a sensitivity of 59% suggest that cavernosography as the only screening method for venous leakage is not sufficient. In most of the cases, cavernosography is indicated only in consideration of venous leakage surgery.
