What is urachal fistula?
VerifiedRestoring balance, one patient at a time.
Urachal fistula may be related to increased abdominal pressure, abnormal embryonic development, incomplete urachal atresia, etc. The specific analysis is as follows:
1. Increased abdominal pressure
If the child's abdominal pressure is high after birth, resulting in increased bladder pressure, urine in the bladder can pass through the fistula and flow out through the urachal part, resulting in urachal fistula.
2. Abnormal embryonic development
If the child is affected by external factors during embryonic growth and development, resulting in abnormal urachal development, resulting in local closure.
3. Incomplete urachal atresia
If the child's urachal atresia, resulting in urachal duct and bladder communication, urine in the bladder will flow out through the urachal duct, resulting in urachal fistula.
