[A case of a urachal fistula].

The authors report a case of urachal fistula diagnosed after repeated omphalitis, this disease was associated with coronal hypospadias. Diagnosis was done thanks to a fistulography; subsequently, during the operation, to evidence the fistula, this was injected with methylene blue, this expedient showed that the fistula was longer than that disclosed from fistulography. To carry out a complete extirpation of the fistula the authors were bound to make a cystotomy. The course after operation was good and the patient discharged after a few days. After 5 years the patient is in perfect health. This case allowed some anatomic, clinical and semeiotic considerations.
