Plastic surgery of the ureteropelvic junction with a pedicle stomach flap

Experiments were carried out on dogs on the application of a pedicle flap cut from the stomach in plastic surgery of the ureteropelvic junction. The experiments showed that the flap healed well without any stenosis at the site where it was sewn in. An analysis of microscopic patterns showed that there was primary repair of the ureter wound which was the result of an adequate supply of blood to the flap.
