Living with Early urethral obstruction sequence

A rare condition in boys present from birth that affects the bladder, belly wall, and testicles.

Understanding Early urethral obstruction sequence

Early urethral obstruction sequence is a rare condition present at birth that affects the urinary tract, abdominal wall, and testicles in males.

In its most complete form, it includes a very large bladder (megacystis) with bladder muscle that doesn't work normally. Boys also have undescended testicles. The belly muscles are thin, and the skin over the belly is loose and wrinkled, giving a 'prune-like' look.

Signs & symptoms

GARD doesn't list specific symptoms for this condition separately, but the summary describes these features:

  • Very large bladder (megacystis)
  • Bladder muscle that doesn't work normally
  • Undescended testicles
  • Thin belly muscles
  • Loose, wrinkled belly skin

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.
