Incision and catheterization of ureteropelvic transition stenosis

As early as 1943, Davis was based on the theory of regenerative repair of mucous membrane smooth muscle of the renal pelvis, ureter and bladder. The large segmental stenosis of the ureteropelvic junction was not deformed after incision, and only the stent tube was placed to allow the defect to be opened. Regeneration ability repairs healing and gains initial success, and is then used by others in the clinic. Treatment of diseases: ureteropelvic junction obstruction Indication Renal ureteral ureteral stenosis and incision catheterization is applicable to: If the ureteral stricture is more than 1cm, if the renal pelvic wall flap is used, it is often impossible to repair and enlarge the lumen. If the ureter is too short after resection of the stenosis, and the ureteropelvic anastomosis can not be performed, the incision can be considered. One side wall, under the guidance of the stent tube, is expected to be fully regenerated and repaired to obtain the normal diameter. Contraindications Renal ureteral ureteral stenosis can be applied to any ureteral stenosis, but because of the long time after placement of the stent tube, the surgical effect is not very stable, rarely used by modern urologists. Anyone who can use other surgery to relieve obstruction should not use this procedure. Surgical procedure 1. Expose the renal pelvis and free the full length of the ureteral stenosis segment, make a longitudinal incision of the stenotic full-length ureteral segment, and cut the entire layer to the normal part of both ends. 2. Insert a thicker stent tube through the pelvic incision and pass through the stenosis to the normal ureteral segment. F5 or F4 can be used in children, and F7~8 stent tubes can be used in adults. The incision is not sutured, the surface is covered with loose fibrous tissue or fat, or slightly fixed with a thin wire. The tail end of the stent tube is led out of the body. The ureteral incision is placed on the cigarette. The incision was sutured in layers and the stent tube was fixed to the skin to prevent slipping off.
