Umbilical ureteral remnants are umbilical ureteral cysts presenting as cystic masses in the lower abdomen medially, not changing with body position and superficially located in close relationship to the abdominal wall. Large umbilical ureteral cysts resemble intra-abdominal tumors and can compress the intestine, causing abdominal pain and other symptoms. They can also become abscesses due to secondary infection. Both abscesses or cysts can rupture and perforate outside the abdomen, or rupture into the bladder or into the abdominal and pelvic cavities. According to clinical examination, superficial cystic swellings in the subumbilical region vary in size, with the larger ones being palpable and mostly asymptomatic. In the case of secondary infection, a local inflammatory response is seen, and the diagnosis can be clarified by combining ultrasound, CT, cystography and other imaging examinations. Patients with residual umbilical ureter are advised to eat foods that enhance the immunity of the body; foods that are antibacterial and anti-inflammatory; and foods that are easily digested and absorbed. Avoid eating foods that easily nourish bacteria; such as fatty meat, lard, butter; foods that are not easily digested and absorbed; such as rice cakes, rice poop, glutinous rice; spicy and stimulating foods; chili pepper, pepper, raw garlic. The following foods are recommended to eat less or not: 1, fatty meat Fatty meat contains a lot of fat, easy to nourish bacteria, leading to increased inflammatory infection, aggravation of the disease, is not conducive to the recovery of patients. It is advisable to eat low-fat food. 2, rice poop rice poop is a relatively difficult to digest food, easily lead to slow intestinal peristalsis, abdominal distension, affecting the absorption of nutrients, is not conducive to recovery. It is advisable to eat light and easily digestible food. 3. Raw garlic Raw garlic is a stimulating food, which can easily stimulate the gastrointestinal mucosa, leading to edema and congestion, affecting the absorption of nutrients in the intestine, which is not conducive to recovery. It is advisable to eat light food.
