METHOD OF URETER FORMATION (VERSIONS) Russian patent published in 2009 - IPC A61B17/00 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, surgical urology, can be used for restoration of ureter defect. Laparotomy is performed. Tube from peritoneum is used to replace ureter defect. After exposing ureter defect, parietal peritoneum is dissected. Peritoneum edge 4-5 cm wide is mobilised at the level of ureter defect. Catheter is placed on free end of parietal peritoneum. Catheter is introduced into ureter end. Catheter is wrapped up with free edge of parietal peritoneum. Edge of parietal peritoneum is sutured to its fixed edge. Peritoneal tube is formed. Upper end of peritoneal tube is sutured to upper end of ureter. Lower end of peritoneal tube is sutured to lower end of ureter. Catheter is passed through urinary bladder and led out through urethra. Further, "П"-shaped flap is cut out of iliac muscle. Tube from parietal peritoneum is surrounded by the flap. Flap is sutured, forming muscle tube. Upper end of muscle tube is sutured to upper end of ureter. Lower end of muscle tube is sutured to lower end of ureter. In performing second version, after formation of peritoneal tube, created tube from parietal peritoneum if wrapped with lavsan fabric. Free edges of lavsan fabric are sutured. Second layer of new ureter wall is thus formed. Tube ends are sutured in the upper part to first part of ureter, and in the lower part to urinary bladder. Further, synthetic tube is surrounded with "П"-shaped flap, formed from iliac muscle. Muscle tube is formed. Upper end of muscle tube is sutured in the upper part to upper end of ureter, and lower end of muscle tube is sutured to urinary bladder.

EFFECT: claimed method allows to create conditions for urine outflow without intestinal infection, eliminate complications connected with application of small and large intestine for urine diversion, ensure adequate blood supply to formed ureter, replace ureter defect for long period of time.
