FIELD: medicine.
SUBSTANCE: method involves substituting ureter defect with vermiform appendix with neurovascular its mesentery structure being retained. The vermiform appendix is excised together with blind gut segment having diameter of 10-15 mm. Opening is made in urinary bladder wall at least 10 mm as large in diameter. The produced blind gut segment with vermiform appendix is end-to-side implanted into the opening. The ureter is transected 4 cm or more far from the stricture boundary. After excising the tip, end-to-end anastomosis is created between the distal vermiform appendix end and ureter.
EFFECT: reduced stenosis risk in anastomosis zone; improved antireflux action.
