Patent urachus and infected urachal cyst in an adult: a case report.

Urachal abnormalities are usually diagnosed early in life, so the finding of a patent urachus associated with an infected urachal cyst in a 21-year-old man as reported by the author is rare and of interest. The condition was managed by excision of the urachus, the cyst, the umbilicus and dome of the bladder, which is the preferred treatment. The author reviews other urachal anomalies and the complications arising from them.
