Sinus de l'ouraque révélé par une suppuration ombilicale à l'âge adulte

A defect involving partial or total obliteration of the urachal canal after the fifth month of gestation can result in four types of benign abnormalities. Patent urachus (50%) is diagnosed during the neonatal period, while in adults, the most frequent form is a urachal cyst (30%), with sinuses (15%) and the diverticula (5%) being very rare. The urachus and its implantation base on the bladder must be removed surgically. Laparoscopic surgery offers a valuable alternative to open-surgery and probably leads to less morbidity and shorter convalescence in active young subjects.
