We describe a new surgical technique (the vaginal plastron) for the treatment of cystocele by the vaginal route. The technique is based on bladder support by a vaginal strip, isolated from the anterior colpocele, left attached to the bladder, associated with a suspension of this strip by its fixation to the tendinous arch of the pelvic fascia by six lateral sutures (3 on each side of the plastron). Proposed as a curative treatment of cystocele and combined with the Richter fixation, the plastron provides a surgical solution to the problem of cystocele relapse arising after vaginal treatment of prolapse by sacro-spino-fixation alone (10 to 20% according to Richter).
