Vesicoamniotic shunting is typically reserved for treatment of fetal obstructive uropathy. We report a case of congenital megacystis without anatomic urinary obstruction in whom a vesicoamniotic shunt was used to improve fetal hemodynamics as measured by Doppler velocimetry.

Objective: We estimated the potential outcomes, costs, and cost-effectiveness of the Vortex shunt, a novel fetal vesicoamniotic shunt (VAS), compared to standard shunts for treating fetal lower urinary tract obstruction (LUTO).
Method: We designed a decision-analytic model comparing the Vortex shunt to current shunts using a theoretical cohort of 1000 pregnancies equivalent to the annual U.S.

Fetal lower urinary tract obstruction (LUTO) encompasses a spectrum of rare congenital anomalies affecting the fetal urinary system, leading to significant morbidity and mortality. This condition, arising from various anatomical anomalies such as posterior urethral valves (PUV), urethral atresia, and cloacal malformations, disrupts normal urine flow, resulting in secondary complications such as pulmonary hypoplasia and renal impairment. Current management strategies, including fetal vesicoamniotic shunting (VAS) and fetal cystoscopy, aim to alleviate obstruction and mitigate associated risks.

Purpose: Intrauterine vesicoamniotic shunting (VAS) was shown to affect survival of male fetuses with megacystis in suspected lower urinary tract obstruction (LUTO). Data on postnatal management are largely lacking. We aim to describe the pathologies diagnosed in children born after vesicoamniotic shunt placement in early pregnancy for megacystis.

Background: Fetal lower urinary tract obstruction (LUTO) is a rare congenital anomaly in which the bladder cannot empty properly. The clinical presentation is variable. On the severe end of the spectrum, the amniotic fluid index can be sufficiently low, resulting in fetal lung development that is incompatible with life outside the womb.

Introduction: Prenatal lower urinary tract obstruction (LUTO) is a rare and challenging condition with potential severe morbidity and mortality. Prenatal shunting methods, specifically vesicoamniotic shunting (VAS) and fetal cystoscopy, aim to manage this condition. However, comprehensive education and training are hindered by the rarity of LUTO.
