Infant umbilical ureteric fistula may take about 1 to 2 weeks to gradually return to normal after surgery. The occurrence of umbilical ureteric fistula in infants may have a lot to do with the fact that the urethra does not close completely and is a sign of congenital developmental abnormalities. Surgery for umbilical ureteric fistula can remove the localized fistula and close the top of the bladder in a timely manner, which will cause some damage to the local tissues and may require about 1~2 weeks of recovery time after the surgery. After umbilical ureter surgery in infants, the wound needs to be disinfected regularly, and the intra-abdominal pressure should be avoided by avoiding crying, which will help the recovery after surgery. After umbilical catheter surgery, the local tissues will need to grow and heal slowly. It is important to review the recovery of the surgical site on a regular basis, and if urine leakage occurs again at a later stage, it is important to consult a doctor promptly for examination.
