The invention relates to a method for repairing urethral polyglycollide (PGA) braiding urethral scaffold support system, weaving method of the bracket by three dimensional axial preparation, including: (1) 48tex polyglycollide (PGA) filament, PGA woven on a mandrel, the gear ratio is 132 / 28, the machine speed is set to 6 to 7; (2) at 90 to 105 DEG C type 5min; (3) PGA woven layer on the mandrel from the back, in the 2.5wt% 3wt% chitosan slurry soaking for 30 minutes, naturally dried, frozen in dry environment under 50 DEG C for 4 hours, that is. The preparation method of the invention is simple and the cost is low; the knitted type urinary catheter bracket has the apparent appearance of the bionic urinary catheter, and the stent is degraded completely.
