a urachus that unites the bladder of a child with amniotic fluid during its intrauterine development. 4-5 months pregnant, during fetal development, urahusa typically grows and forms an umbilical midline ligament. Newborn children and adults on the ground can be seen urahusa obliterated bespolostnoy strand, advancing from the apex of the bladder to the navel, but, in some cases, complete fusion body does not occur, which leads to certain pathologies. These include:
- Umbilical fistula (with cleft near the navel of the urahusa). This variant is characterized by the regular discharge anomalies in the navel leading to his irritation;
- Vesicoumbilical fistula (occurs when the full cleft urahusa). In this case there is a constant flow of urine in the navel;
- Cyst urahusa. This cleft urinary duct is formed in the middle part of cystic formation filled with mucous secretion. Urahusa cyst can reach a man's fist.
According to statistics, the cyst urahusa men diagnosed 3 times more likely than female patients.
The symptoms of cysts urahusa
This urologic disease is detected with difficulty: a clinically urahusa cyst may not manifest itself for a long time, while maintaining the small size. When infected cyst contents urahusa (meconium, serous fluid, mucus) may be its festering, accompanied by a rise in temperature, painful sensations in the lower abdomen. When the inflammatory process may be symptoms of intoxication, abdominal pain, flushing of the skin below the navel.
A large cyst urahusa can manifest as tumor formation at palpation of the abdominal wall in the navel. Festering cyst may break into the abdominal cavity (and the cause of peritonitis), bladder (fistula forming the bladder) or through the abdominal wall (umbilical forming a fistula). Umbilical fistula manifests periodic release of pus from the umbilical hole, increasing straining or pressing on the area of the umbilical ring, irritation, weeping skin, as well as over omphalitis.
Diagnosis of cysts urahusa
diagnosis is important to distinguish the disease from umbilical cord cyst, bladder diverticulum, anterior abdominal wall hernias in the presence of similar symptoms with a cyst urahusa. For this purpose, patients received cystoscopy, cystography, MRI, ultrasound of the bladder and fistulography - research allows us to determine whether the urinary stream nezarosshy message to the bladder - produced only after decrease of inflammatory manifestations.
When festering cysts urahusa patients are often admitted to hospital with symptoms of "acute abdomen" - in this case to establish the correct diagnosis can only be in the process of laparotomy or laparoscopy.
Treatment of cysts urahusa
Treatment of the disease - cleft symptomatic urinary flow - operative, is to remove the cyst urahusa. The operation is characterized by extraperitoneal dissection education. In the case of abscess formation are promptly opened and cleaned abscess cavity, then, in the "cold" period carried the standard operation urahusa cysts.
With the development of omphalitis umbilical fistula formation or experts appointed by the course of conservative therapy (bandages, UFO, antibiotics), and only after decrease inflammation symptoms carried out surgery.
