Abstract
A 4-month-old girl presented pus discharge from a tiny midline opening over the pubic symphysis. There were no other symptoms nor evidence of infection. A fistulography revealed a tract that extended from the skin into the neck of the bladder and ascended toward the umbilicus but communicated with neither of them. A surgical procedure was undertaken. The tract went deep toward the symphysis pubis and ascended toward the umbilicus, parallel to the median umbilical ligament. The infraumbilical tract ended blindly 1.5cm caudal to the navel, where it was excised. The histological examination demonstrated transitional epithelium.
