[Evaluation of preoperative cavernosometry and cavernosography in erectile dysfunction of presumed venous origin].

During the period November 1988 to September 1992, 42 patients with erectile dysfunction underwent preoperative dynamic cavernosometry and cavernosography. Radiologically visible venous leakage was demonstrated in all cases but one. At a maintenance flow of more than 20 ml/min, venous leakage was always demonstrable and the types of veins opacified were stereotype. Therefore, clinically relevant leakage can be documented on the basis of cavernosometry. A surgical approach to penile venous leakage with resection of the deep dorsal vein and ligation of all superficial anastomoses including the superficial dorsal vein will eliminate the most common types of radiologically visible veins.
