happens for various reasons. Most common is failure to use the stents aggressively or maybe smaller sizes were unavailable or no Rx was written for lubricating anesthetic jellies or creams. Also perhaps small genitalia to start out with.  Before opting for a colonic graft which may have associated problems, consider creation of another vaginal space and re-epithelialization.  Tincture of time takes care of the latter as opposed to skin grafting with harvesting scars.

Vaginoplasty (Male to Female)
Example #13: 13/1-13/3
Patient presented with vaginal stenosis. Her depth was only 1 1/2″. This was recovered with a suburethral approach restoring the pelvic space, and allowing skin to epithelialize in. Her responsibility: frequent dilations to keep the space open for several weeks until new skin could re-line the vaginal vault.
