Fetal diagnostic cystoscopy was performed to determine prenatally the cause of LUTO and to ablate the posterior urethral valves (PUV).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 50 fetal cystoscopies were performed, revealing PUV in 31 (62%) fetuses, urethral atresia (UA) in 14 (28%) fetuses, and urethral stenosis (US) in 5 (10%) fetuses. Two fetuses had trisomy 18 diagnosed after fetal cystoscopy and were excluded from the present analysis. Fetal cystoscopy was accurate in the diagnosis of the etiology of LUTO in 32\/35 (91.4%). There were no survivors in the UA group. One fetus with US underwent urethral stenting and survived with normal renal function at 2\u2009years of life. Among the infants with PUV, 17\/30 (56.7%) infants survived, and 13\/17 (76.5%) had normal renal function at 1\u2009year of life; 15\/28 (53.6%) infants survived, and 11\/15 (73.3%) had normal renal function at 2\u2009years.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Fetal cystoscopy is accurate in the diagnosis of the etiology of LUTO and serves as a guide to the specific prenatal treatment. This procedure is associated with modest long\u2010term survival (54%) but with adequate preserved normal renal function in two thirds of the infants among fetuses with PUV. \u00a9 2016 John Wiley
