NCT02315521

Brief Summary

The investigators propose a standardized prenatal management, based on the scientific evidence published in the literature, to manage prenatally fetuses with lower urinary tract obstruction (LUTO). The present study is a prospective registry that will evaluate and validate this standardized prenatal management for LUTO.

Outcome Measures

Primary Outcomes (1)

  • Survival rate

    The survival rate from the prenatal period up to 24 months of life will be evaluated

    Survival rate since prenatal period to 24 months of life

Secondary Outcomes (3)

  • Postnatal renal function at 6 months of life

    During neonatal period and at 6 months of life

  • Postnatal renal function at 12 months of life

    During neonatal period and at 12 months of life

  • Postnatal renal function at 24 months of life

    During neonatal period and at 24 months of life

Study Arms (4)

Group 1

Fetuses with LUTO before 18 weeks

Procedure: Fetal Intervention for LUTO

Group 2

Fetuses with LUTO between 18 and 30 weeks

Procedure: Fetal Intervention for LUTO

Group 3

Fetuses with LUTO between 30 and 34 weeks

Procedure: Fetal Intervention for LUTO

Group 4

Fetuses with LUTO after 34 weeks

Interventions

Fetal vesico-amniotic shunting placement consists in placing a shunt (stent) percutaneously from fetal bladder to the amniotic cavity under ultrasound guidance. Fetal cystoscopy will be performed using a thin scope that will be introduced to the fetal bladder for evaluation of the cause of the obstruction and ablation of the posterior urethral valves.

Also known as: Fetal vesico-amniotic shunting, Fetal cystoscopy

Sexall
Healthy VolunteersNo
Age GroupsChild (0-17)
Sampling MethodProbability Sample
Study Population

All pregnant women referred to our Fetal Center with confirmed diagnosis of fetal LUTO. The diagnosis of fetal LUTO is based on the presence of enlarged bladder and bilateral hydronephrosis.

You may qualify if:

  • \- Pregnant women whose fetuses have diagnosis of LUTO independently from the gestational age at diagnosis.

You may not qualify if:

  • Presence of abnormal chromosomal/genetic disease
  • Presence of other associated structural anomaly that is not part of LUTO.
