Abstract
In the period 1982 to 1985, 73 placements of catheter shunts for fetal obstructive uropathy and 44 drainage procedures for obstructive hydrocephalus were reported to a voluntary international registry. The attempts to decompress the obstructed fetal urinary tracts resulted in the survival of 30 fetuses (41 percent), with a procedure-related death rate of 4.6 percent. Pulmonary hypoplasia was the major cause of death in both untreated and treated fetuses. Although the natural history of fetal obstructive uropathy has not been well studied, the outcome of intervention for selected fetuses with posterior urethral valve syndrome was encouraging.
