The bicycle seat stool in the treatment of vaginal agenesis and stenosis: a preliminary report.

A new pressure technique for treatment of vaginal agenesis and stenosis, with the use of the bicycle seat stool, specifically designed Lucite dilators, and the patient model, is described. Experience with this method in 24 patients over a 5-year period produced coital function in 10 of 12 patients with vaginal agencies and 10 of 14 patients and various types of stenosis. Favorable experience with this technique, as compared to a previous 5-year period, in which the majority of vaginal agenesis was managed by the Abbe-McIndoe operation, has led to reversal of primary therapy of vaginal agenesis and stenosis from a surgical to a nonsurgical approach.
