Which characteristic is NOT associated with Eagle-Barrett syndrome?

Eagle-Barrett syndrome, also known as prune belly syndrome, is primarily characterized by a triad of features: a large, flaccid abdominal wall, undescended testes, and urinary tract anomalies, which often include hydronephrosis. The large, flaccid abdominal wall occurs due to a deficiency in the abdominal muscles, while undescended testes are common because of the associated developmental anomalies. Hydronephrosis results from obstruction of urinary flow due to abnormalities in the urinary tract, which is a frequent issue in this condition.

Chronic fetal hypoxia is not a defining characteristic of Eagle-Barrett syndrome. While any congenital condition can be associated with various degrees of fetal distress or hypoxia due to complications during pregnancy or delivery, it is not directly linked to the developmental abnormalities that constitute Eagle-Barrett syndrome. The focus of the condition is primarily on the specifics of abdominal wall musculature, undescended testes, and urologic complications rather than respiratory or hypoxic issues. Therefore, chronic fetal hypoxia is not an associated characteristic of this syndrome.
