A patent urachus is an anomaly, and repair is recommended for these defects occurring at birth.
Surgery for patent urachus repair may require several days' hospitalization, during which infants can be fed as normal.
surgery to correct a urachus (a tube that connects the fetal bladder to the umbilical cord) that fails to close after birth.
If the urachus remains completely open, it is known as a patent urachus. This type of abnormality makes up 50% of all urachal anomalies.
The condition occurs three times more often in male infants than in females.
If the urachus remains open all the way to the bladder, there is the danger that bacteria will enter the bladder through the open tube and cause infection.
Risks are the same as for those patients receiving any anesthesia: a reaction to medication and/or breathing problems. There is also the risk of bladder infection or bladder leaks.
Normal anatomyThe urachus is a tube that connects the bladder to the umbilicus during fetal development. After birth, the urachus normally closes and becomes a ligament.IndicationsSurgery is recommended for a patent urachus that does not close after birth. There is some variablity in the degree of the defect. Sometimes, only the umbilical end of the urachus fails to close, generating a urachal sinus, which does not connect with the bladder, but simply eneters the skin for a short distance. These can usually be excised locally. If the entire urachus is patent all the way to the bladder, the urachus must be excised and the bladder closed.IncisionWhile the infant is deep asleep and pain-free (using general anesthesia), an incision is made in the lower abdomen, below the umbilicus.ProcedureThe urachus is located and removed from the umbilicus and the bladder. The bladder opening is repaired, and the incision is closed.AftercareThe outcome is usually excellent. The infant can be fed normally and should recover rapidly. A few days of hospitalization is all that is usually required.Reviewed ByReview Date: 09/03/2010David C.

the urachus, a tube that can measure from 1.2-3.9 in (3-10 cm) long and 0.3-0.4 in (8-10 mm) in diameter
extending from the front dome of the bladder to the umbilicus.
In order to patent a new invention, one has to get a grant of property right from the US Patent and Trademark Office. Depending on the type of patent needed, one will have to fill out an application for either utility, design, or plant patent.
Uracus or urachus is located at the apex of the urinary bladder, connecting it to umbilicus.
