Abstract:Lower urinary tract obstruction (LUTO) refers to a kind of congenital malformation caused by fetal insufficiency or lack of urination due to mechanical or functional obstruction below the bladder, of which the incidence is 2-3/10 000. LUTO can cause fetal pulmonary hypoplasia and renal dysfunction, which seriously affects fetal survival during perinatal period. The main current clinical measures as the treatment of LUTO are fetal cystoscopy and vesico-amniotic shunting. By comparing fetal cystoscopy and vesico-amniotic shunting in the long-term renal function, the implementation of technology and the complications, this article will highlight the pros and cons of fetal cystoscopy in the current diagnosis and treatment of LUTO.
