Patient selection criteria in the surgical treatment of veno-occlusive dysfunction.

Abstract

We evaluated short and long-term results of simple and complex venous surgery in patients with veno-occlusive dysfunction unresponsive to maximum recommended doses of intracavernous alprostadil, who were selected with newly developed diagnostic indicators. A total of 23 impotent men with a mean age of 41 years (range 20 to 50) underwent complex penile venous surgery. Only patients fulfilling at least 3 criteria were included in study. The criteria were mild cavernous leak assessed by cavernosometry (grades 1 and 2), more than 30% cavernous smooth muscle tissue (histomorphometric analysis), normal analogical corpus cavernosum electromyography recordings according to international standards, cavernosal oxygen tension greater than 65 mm. Hg at erection and age younger than 50 years. Of 23 patients 17 (74%) had normal erections within a year after surgery, and 5 of them (29%) complained of recurrent erectile dysfunction. At long-term followup 6 of 12 patients had spontaneous erections. Careful selection with advanced diagnostic techniques should be mandatory before performing venous surgery in patients with high degree veno-occlusive dysfunction as the only alternatives are major therapeutical solutions.
