What is the cause of vesicoureteral reflux

Bladder ureteral reflux generally refers to vesicoureteral reflux, vesicoureteral reflux is not congenital defects, neurogenic bladder and posterior urethral valve factors.

1, congenital defects

due to embryonic bladder ureteral wall muscle development is not complete, bladder triangle muscle dysplasia, resulting in abnormal anti-reflux mechanism, resulting in vesicoureteral reflux.

2, neurogenic bladder

if suffering from neurogenic bladder, due to urodynamic changes, urinary tract infection can occur, and thus damage the normal anti-reflux mechanism, resulting in vesicoureteral reflux.

3, posterior urethral valve when

the presence of posterior urethral valve, can affect the discharge of urine in the bladder, with the increase of urine, bladder pressure gradually increased, urine can flow back into the ureter.
