This paper presents a description of the technique, the indications, and the results of a new ileosigmoid substitute for the human bladder. Like most "new" operations, it is largely a combination of techniques separately described by other surgeons.
The fundamental principle of substituting a closed sleeve of sigmoid for the excised bladder was reported by McLean et al.,1 and to them I owe the basic plan for the modifications I have devised.

He anastomosed the prostatic urethra to the side of the sigmoid sleeve and brought out the distal limb of the sleeve as a temporary colostomy. This colostomy was closed in a secondary operation.
