[Replacement of the lower third of the ureter via the bladder (author's transl)].

The author suggests a special incision in the bladder permitting the formation of a tube using a strip of bladder long enough to permit an anti-reflux vesico ureteral reimplantation. The method is a combination of the Boari and the transverse bipartition described by Turner Warwick. Extraperitonealization of the hemi-bladder opposite to the diseased ureter and section of the umbilical artery. Transverse anterior cystostomy at mid height of the bladder. The mobilized dome of the bladder is stitched up to the psoas muscle above the iliac vessels. Creation of a rectangular flat, the anterior limit of which is the superior margin of the transverse cystostomy, of which the upper part is a split which cuts the dome of the bladder from front to back, of which the posterior limit is a split on the posterior wall of the bladder, parallel to the anterior incision. The length must not be larger than one and one half the width of the flap. Reimplantation of the ureter, creation of the tube and closure of the bladder is done without difficulty. Drawings illustrate the technic. Four cases are reported with three successes.
