The posterior urethral valve is a congenital anomaly caused by the fold of the posterior urethral mucosa, which forms a thin diaphragm that prevents urine outflow from the bladder. The anterior urethral valve usually has little effect on the urinary system, while the posterior urethral valve is the leading cause of early and severe renal failure in children.
