Abstract
Objective To explore the biomechanical effect of ureteral submucosal tunnel during ureteral reimplantation.Methods Different vesicoureteral models were established with ANSYS 2020 R2 software.Fi-nite element analysis(FEA)of biomechanics during storage and urination periods was conducted for evaluating the stress and strain distribution of vesicoureteral junction under different models.Results Simulation results indicated that during urine storage period,maximal equivalent stress of Al/A3 type tunnel sections was 1%and 3%higher than that of A2 type tunnel sections;During urination period,maximal equivalent stress of Al/A3 type tunnel segments was 9%and 12%higher than that of A2 type and the difference was insignificant.When compared with type A2,storage and urination periods of type B decreased by 46%and 53%respectively.Conclusions Ureteral submucosal tunnel is essential for ureteral reimplantation.However,changing its length appropriately has no significant effect on biomechanics.关键词
