Pelvic osteotomy in the treatment of ectopia vesicae.

This is a preliminary report on a method of pelvic osteotomy which we have found of value in the treatment of ectopia vesicae. The operation involves complete division of both iliac bones from crest to greater sciatic notch, together with the sacro-tuberous ligaments. A few days later fibrous tissue is removed from the pubic symphysis, the bladder is buried, and the divarication of the recti and the skin defect are repaired. There is only moderate tension on the suture lines because the inward rotation of both sides of the pelvis which is possible after iliac osteotomy enables the pubic rami to be approximated (Figs. 1 and 2).
