Urachal cyst and urachal fistula (Urology), in embryonic development, the bladder along the abdominal wall from the umbilicus down during descent, because there is a thin tube umbilical connected with the bladder, was born into a fibrous band back. If both ends of the urachus after birth has been blocked, the middle section is not closed, and the formation of congenital urachal cyst, urachal full if no closed, and the formation of urachal fistula. Also called open urachus, bladder outflow of urine from the umbilicus of abdominal wall. Regardless of the kind of disease, due to a secretion urachal are easy to cause infection, bleeding. The rare disease, about 30 million births, 1 case, more common in men. Good treatment of this disease, surgery is the most important method of treatment. Such as the stimulation of long-term chronic infection, the disease has become hateful - urachal cancer.
Symptoms:
1. Anterior abdominal wall muscles under the deep center of mass, such as infection, abscess formation may develop fever, anterior abdominal tenderness. 2. Urachal fistula can be seen out of urine from the umbilicus, throat infection appeared Cullen. 3. There are urinary tract infections and bladder irritation.
Diagnosis based on:
1. Hit a deep midline anterior abdominal mass. 2. Such as the formation of cyst rupture sinus, the sinus radiograph shows contrast agent injected into cyst cavity. 3. Umbilicus with urine flow, the contrast agent injected into the u


mbilicus, or excretion urography may show the fistula.
Treatment:
Treatment principles 1. Use of antibiotics and dressing techniques to control infection. 2. Surgical excision of the cyst or urachal fistula.
The principles of the disease without medication infection, no need for antibiotics before surgery, only patients with common antibiotics can prevent infection. However, if urinary tract infection and urachal abscess, should be the use of antibiotics, and intravenous drug use as well. 1-2 kinds of antibiotics is usually sufficient to use, mainly rely on surgical treatment.
Prevention of common sense:
Urachal cyst and urachal fistula is a major cause of pediatric umbilical infection, such as the navel of water that should be thought of children and the sick go for medical treatment, delay treatment if the infection will spand endanger children with life. During adolescence, and sometimes difficult to diagnose and should be appendicitis abscess, ovarian cysts, intestinal Meike ear diverticulitis, tuberculous peritonitis identification.
During embryonic development, the bladder along the abdominal wall from the umbilicus down during descent, because there is a thin tube umbilical connected with the bladder, was born into a fibrous band back. If both ends of the urachus after birth has been blocked, the middle section is not closed, and the formation of congenital urachal cyst, urachal full if no closed, and the formation of urachal fistula.

Clinical manifestations
1. Anterior abdominal wall muscles under the deep center of mass, such as infection, abscess formation may develop fever, anterior abdominal tenderness. 2. Urachal fistula can be seen out of urine from the umbilicus, throat infection appeared Cullen. 3. There are urinary tract infections and bladder irritation.
Diagnosis is based on
1. Hit a deep midline anterior abdominal mass. 2. Such as the formation of cyst rupture sinus, the sinus radiograph shows contrast agent injected into cyst cavity. 3. Umbilicus with urine flow, the contrast agent injected into the umbilicus, or excretion urography may show the fistula.
Treatment principles
1. The use of antibiotics and dressing techniques to control infection. 2. Surgical excision of the cyst or urachal fistula.
Medicine principles
This disease without infection, no need for antibiotics before surgery, only patients with common antibiotics to prevent infection. However, if urinary tract infection and urachal abscess, should be the use of antibiotics, and intravenous drug use as well. Generally adequate with 12 antibiotics, mainly rely on surgical treatment.
Auxiliary examination
Urachal cyst found mainly by B-ultrasound cystic mass under the abdominal wall center; or have the navel of urine flow phenomenon, fistula angiography should be done can often be confirmed or provide meaningful clues.
Efficacy evaluation
1. Cure: removal of pathogens, the infection disappeared, the wound healed. 2. Improvement: infection control, but the of the disease is not completely excised or recurrence. 3. Healed: of the disease exist, recurrent infection.
