Urachal sinus: An atypical case and review of the literature.

Urachal sinus is a rare type of urachal abnormality. It happens because of blind focal dilation at the umbilical end and has increased risk of infection. We report the case of a 23-year-old female with abdominal pain and umbilical discharge. Ultrasound detected a possible infected urachal sinus which was initially treated with antibiotic therapy. Urachal sinus excision and laparoscopic bladder raffia was later performed with no recurrence at present. Diagnosis of this pathology is essential given that surgery is curative and avoids complications such as neoplastic transformation.
