The following: Posterior urethral valves form a cusp-like obstruction just below the bladder neck. Anterior urethral valves are due to a urethral out-pouching, this fills with urine and distal end becomes a "flap valve" which obstructs. Urethral atresia or congenital stricture. Ureterocele, ectopic or orthotopic can block bladder neck or prolapse causing obstruction. Vaginal atresia + urogenital sinus.

This happens in boys and has a spectrum of presentation and treatments depending on the severity of the blockage and there may be issues with the bladder and kidneys because of the blockage.
