[Penile venous outflow occlusion: a comparison of erectile function and cavernosometry before and after percutaneous...

After percutaneous transpenile or retrograde venous occlusion for the treatment of a cavernous leak, the clinical results were correlated with cavernosometric flow measurements in 27 patients. In 15 patients, venous occlusion led to a reduction of the maintenance flow: in patients who showed improvement there was an average reduction of 30 ml/min, in those without improvement or deterioration it averaged 0.3 or 13 ml/min respectively. In 7 patients there was increased flow (up to +21 ml/min). One of these patients showed improved erectile function; the remaining 6 showed no change as was also the case in 5 other patients who had no change in cavernosometric measurements. Our findings suggest a multifactorial cause of the venous leaks.
