[Complications of the urachus in adults].

The authors observed 7 patients aged from 19 to 74. Five of them were operated upon. One patient died from anaerobic neclostridial phlegmon of the anterior abdominal wall which appeared after an injury of the not noticed urinary duct. Laparotomic accesses passing aside form the area of possible localization of the urinary duct were more justified. When operating on the paraumbilical area it is expedient to make a revision for the detection of the urachus and associated abnormalities on the anterior abdominal wall.
