Flap ureteroplasty for segmental structure of middle third of ureter.

ABSTRACT

A technique is described for repair of segmental stricture of the middle third of the ureter utilizing spiral or vertical flap from the proximal dilated ureter. In all cases a 10 F polyethylene ureteric stent with a ureterotomy exit 5 cm. distal to the repair site was used. Twenty-eight ureters in 27 patients were repaired by this technique, with good results in all except 3 cases which showed postoperative residual dilatation three months after surgery.
